# Generic Appveyor build script for boostorg repositories
|
||||
# See: https://github.com/boostorg/boost-ci/
|
||||
#
|
||||
# Instructions for customizing this script for your library:
|
||||
#
|
||||
# 1. Customize the compilers and language levels you want.
|
||||
# 2. If you have more than include/, src/, test/, example/, examples/,
|
||||
# benchmark/ or tools/ directories, set the environment variable DEPINST.
|
||||
# For example if your build uses code in "bench/" and "fog/" directories:
|
||||
# - DEPINST: --include bench --include fog
|
||||
# 3. Enable pull request builds in your boostorg/<library> account.
|
||||
#
|
||||
# That's it - the script will do everything else for you.

The csv file containing the zone_specs used by the
|
||||
boost::local_time::tz_database is intended to be customized by the
|
||||
library user. When customizing this file (or creating your own) the
|
||||
file must follow a specific format.
|
||||
|
||||
This first line is expected to contain column headings and is therefore
|
||||
not processed by the tz_database.
|
||||
|
||||
Each record (line) must have eleven fields. Some of those fields can
|
||||
be empty. Every field (even empty ones) must be enclosed in double-quotes.
|
||||
Ex:
|
||||
"America/Phoenix" <- string enclosed in quotes
|
||||
"" <- empty field
|
||||
|
||||
Some fields represent a length of time. The format of these fields must be:
|
||||
"{+|-}hh:mm[:ss]" <- length-of-time format
|
||||
Where the plus or minus is mandatory and the seconds are optional.
|
||||
|
||||
Since some time zones do not use daylight savings it is not always necessary
|
||||
for every field in a zone_spec to contain a value. All zone_specs must have
|
||||
at least ID and GMT offset. Zones that use daylight savings must have all
|
||||
fields filled except: STD ABBR, STD NAME, DST NAME. You should take note
|
||||
that DST ABBR is mandatory for zones that use daylight savings (see field
|
||||
descriptions for further details).
|
||||
|
||||
|
||||
********* Fields and their description/details *********
|
||||
|
||||
* ID
|
||||
Contains the identifying string for the zone_spec. Any string will
|
||||
do as long as it's unique. No two ID's can be the same.
|
||||
|
||||
* STD ABBR
|
||||
* STD NAME
|
||||
* DST ABBR
|
||||
* DST NAME
|
||||
These four are all the names and abbreviations used by the time
|
||||
zone being described. While any string will do in these fields,
|
||||
care should be taken. These fields hold the strings that will be
|
||||
used in the output of many of the local_time classes.
|
||||
Ex:
|
||||
time_zone nyc = tz_db.time_zone_from_region("America/New_York");
|
||||
local_time ny_time(date(2004, Aug, 30), IS_DST, nyc);
|
||||
cout << ny_time.to_long_string() << endl;
|
||||
// 2004-Aug-30 00:00:00 Eastern Daylight Time
|
||||
cout << ny_time.to_short_string() << endl;
|
||||
// 2004-Aug-30 00:00:00 EDT
|
||||
|
||||
NOTE: The exact format/function names may vary - see local_time
|
||||
documentation for further details.
|
||||
|
||||
* GMT offset
|
||||
This is the number of hours added to utc to get the local time
|
||||
before any daylight savings adjustments are made. Some examples
|
||||
are: America/New_York offset -5 hours, & Africa/Cairo offset +2 hours.
|
||||
The format must follow the length-of-time format described above.
|
||||
|
||||
* DST adjustment
|
||||
The amount of time added to gmt_offset when daylight savings is in
|
||||
effect. The format must follow the length-of-time format described
|
||||
above.

* DST Start Date rule
|
||||
This is a specially formatted string that describes the day of year
|
||||
in which the transition take place. It holds three fields of it's own,
|
||||
separated by semicolons.
|
||||
* The first field indicates the "nth" weekday of the month. The
|
||||
possible values are: 1 (first), 2 (second), 3 (third),
|
||||
4 (fourth), 5 (fifth), and -1 (last).
|
||||
* The second field indicates the day-of-week from 0-6 (Sun=0).
|
||||
* The third field indicates the month from 1-12 (Jan=1).
|
||||
|
||||
Examples are: "-1;5;9"="Last Friday of September",
|
||||
"2;1;3"="Second Monday of March"
|
||||
|
||||
* Start time
|
||||
Start time is the number of hours past midnight, on the day of the
|
||||
start transition, the transition takes place. More simply put, the
|
||||
time of day the transition is made (in 24 hours format). The format
|
||||
must follow the length-of-time format described above with the
|
||||
exception that it must always be positive.
|
||||
|
||||
* DST End date rule
|
||||
See DST Start date rule. The difference here is this is the day
|
||||
daylight savings ends (transition to STD).
|
||||
* End time
|
||||
Same as Start time.

|
||||
The library has several functions that require the creation of a library file.
|
||||
The Jamfile in the build directory (BOOST_ROOT/libs/date_time/build) will
|
||||
produce the <font class="bold">libboost_date_time</font> library
|
||||
that contains these functions. The library is compiled into both
|
||||
static and dynamic (dll) forms. Note that the static library is the
|
||||
prefered form as some compilers have spurious regression test
|
||||
errors using the dynamic library. See the
|
||||
<a href="http://boost.sourceforge.net/regression-logs/">regression test logs at sourceforge </a> for more details.
|
||||
|
||||
<p>
|
||||
<H2><a name="options">Compilation Options</a></H2>
|
||||
<p>
|
||||
By default the posix_time system uses a 64 bit integer and a 32 bit
|
||||
integer internally to provide nano-second level resolutions -- 96
|
||||
bits for each time value. As an alternative, a single 64 bit integer
|
||||
can be used to provide a microsecond level resolution. This alternative
|
||||
implementation may provide better performance and more compact memory usage
|
||||
for many applications that do not require nano-second resolutions.
|
||||
<p>
|
||||
The variable <b>BOOST_DATE_TIME_POSIX_TIME_STD_CONFIG</b>, as defined in
|
||||
build/Jamfile, selects between these options. To select the 64 bit
|
||||
integer implementation simply remove this define from the Jamfile.
|
||||
<p>
|
||||
<H2><a name="portability">Compiler/Portability Notes</a></H2>
|
||||
<p>
|
||||
The Boost Date-Time library has been built and tested with many compilers
|
||||
on many platforms. In general, the more standard compliant the compiler
|
||||
and library combination the more likely the library will be fully supported.
|
||||
However, some compilers and standard libraries have issues. While some
|
||||
of these issues can be worked around, others are difficult to work
|
||||
around. The following compilers <b>fully support</b> all aspects of the library:
|
||||
<ul>
|
||||
<li>GCC 3.x on Linux
|
||||
<li>GCC 3.1 (cygwin) for Windows
|
||||
<li>GCC 3.3 on Mac
|
||||
<li>Borland 5.6.4 for Windows
|
||||
<li>MSVC 7.1 on Windows
|
||||
<li>MIPSpro 7.4 on SGI
|
||||
<li>VisualAge 6.0 on IBM AIX
|
||||
</ul>
|
||||
<p>
|
||||
In particular, a lack of support for standard locales limits the ability
|
||||
of the library to support iostream based input and output. For these
|
||||
compilers a set of more limited string based input-output is provided.
|
||||
In addition, some compilers have regression test failures with the dll form
|
||||
of the library or other issues that may prevent using some aspects of the
|
||||
library.
|
||||
|
||||
Some compilers/standard libraries with known <b>limitations</b> include:
|
||||
<p>
|
||||
<ul>
|
||||
<li>GCC 2.9x on Linux
|
||||
<li>Borland 5.1.1 on Windows
|
||||
<li>Intel 8.00 on Windows
|
||||
<li>Metrowerks 8.3 on Windows
|
||||
<li>MSVC 6 SP5 on Windows
|
||||
<li>MSVC 7 on Windows
|
||||
</ul>

The date_time directory structure has been changed for boost submission.
|
||||
<p>
|
||||
The directory tree has the following structure:
|
||||
<pre>
|
||||
/boost/date_time -- common headers and template code
|

/boost/date_time/gregoran -- gregorian calendar system header files
|

/libs/date_time/test -- test battery for generic code
|

/libs/date_time/test/gregorian -- test battery for the gregorian system
|

/libs/date_time/test/posix_time -- test battery for the posix_time system
|

/libs/date_time/src/gregorian -- cpp files for libboost_date_time
|

<h2><a name="timepoints">Timepoints</a></h2>
|
||||
|
||||
<p>
|
||||
This section describes some of basic arithmetic rules that can be performed with timepoints. In general, Timepoints support basic arithmetic in conjunction with Durations as follows:
|
||||
|
||||
<PRE>
|
||||
Timepoint + Duration --> Timepoint
|
||||
Timepoint - Duration --> Timepoint
|
||||
Timepoint - Timepoint --> Duration
|
||||
</PRE>
|
||||
|
||||
Unlike regular numeric types, the following operations are undefined:
|
||||
<PRE>
|
||||
Duration + Timepoint --> Undefined
|
||||
Duration - Timepoint --> Undefined
|
||||
Timepoint + Timepoint --> Undefined
|
||||
</PRE>
|
||||
<p>
|
||||
<h2><a name="durations">Durations</a></h2>
|
||||
<p>
|
||||
Durations represent a length of time and can have positive and negative values. It is frequently useful to be able to perform calculations with other durations and with simple integral values. The following describes these calculations:
|
||||
<PRE>
|
||||
Duration + Duration --> Duration
|
||||
Duration - Duration --> Duration
|
||||
|
||||
Duration * Integer --> Duration
|
||||
Integer * Duration --> Duration
|
||||
Duration / Integer --> Duration (Integer Division rules)
|
||||
|
||||
</PRE>
|
||||
|
||||
|
||||
<p>
|
||||
<h2><a name="intervals">Intervals (Periods)</a></h2>
|
||||
<p>
|
||||
Interval logic is extremely useful for simplifying many 'calculations' for dates and times. The following describes the operations provided by periods which are based on half-open range. The following operations calculate new time periods based on two input time periods:
|
||||
|
||||
<PRE>
|
||||
Timeperiod intersection Timeperiod --> Timeperiod (null interval if no intersection)
|
||||
Timeperiod merge Timeperiod --> Timeperiod (null interval if no intersection)
|
||||
Timeperiod shift Duration --> Timeperiod (shift start and end by duration amount)
|
||||
</PRE>
|
||||
|
||||
In addition, periods support various queries that calculate boolean results. The first set is caluculations with other time periods:
|
||||
<PRE>
|
||||
Timeperiod == Timeperiod --> bool
|
||||
Timeperiod < Timeperiod --> bool (true if lhs.last <= rhs.begin)
|
||||
Timeperiod intersects Timeperiod --> bool
|
||||
Timeperiod contains Timeperiod --> bool
|
||||
Timeperiod is_adjacent Timeperiod --> bool
|
||||
</PRE>
|
||||
|
||||
The following calculations are performed versus the Timepoint.
|
||||
<PRE>
|
||||
Timeperiod contains Timepoint --> bool
|
||||
Timeperiod is_before Timepoint --> bool
|
||||
Timeperiod is_after Timepoint --> bool
|
||||
</PRE>
|
||||
|
||||
<p>
|
||||
<h2><a name="special">Special Value Handling</a></h2>
|
||||
|
||||
<p> For many temporal problems it is useful for Duration and Timepoint types to support special values such as Not A Date Time (NADT) and infinity.
|
||||
|
||||
In general special values such as Not A Date Time (NADT) and infinity should follow rules like floating point values. Note that it should be possible to
|
||||
configure NADT based systems to throw an exception instead of result in NADT.
|
||||
<PRE>
|
||||
Timepoint(NADT) + Duration --> Timepoint(NADT)
|
||||
Timepoint(∞) + Duration --> Timepoint(∞)
|
||||
Timepoint + Duration(∞) --> Timepoint(∞)
|
||||
Timepoint - Duration(∞) --> Timepoint(-∞)
|
||||
</PRE>
|
||||
<p>When performing operations on both positive and negative infinities, the library will produce results consistent with the following.
|
||||
<PRE>
|
||||
Timepoint(+∞) + Duration(-∞) --> NADT
|
||||
Duration(+∞) + Duration(-∞) --> NADT
|
||||
Duration(±∞) * Zero --> NADT
|
||||
|
||||
Duration(∞) * Integer(Not Zero) --> Duration(∞)
|
||||
Duration(+∞) * -Integer --> Duration(-∞)
|
||||
Duration(∞) / Integer --> Duration(∞)
|
||||
|
||||
</PRE>

<a href="class_date.html#constructfromstring">(reference)</a>

|

<a href="date_algorithms.html">(see date_algorithms)</a>
|

was changed. The order of construction parameters was changed

made to facilitate more generic local time adjustment code.

||||
The library does its best to provide everything a user could want, but there are certain inherent constraints that limit what <i>any</i> temporal library can do. Specifically, a user must choose which two of the following three capabilities are desired in any particular application:
|
||||
<UL>
|
||||
<li>exact agreement with wall-clock time
|
||||
<li>accurate math, e.g. duration calculations
|
||||
<li>ability to handle timepoints in the future
|
||||
</UL>
|
||||
Some libraries may implicitly promise to deliver all three, but if you actually put them to the test, only two can be true at once. This limitation is not a deficiency in the design or implementation of any particular library; rather it is a consequence of the way different time systems are defined by international standards. Let's look at each of the three cases:
|
||||
<p>
|
||||
If you want exact agreement with wall-clock time, you must use either UTC or local time. If you compute a duration by subtracting one UTC time from another and you want an answer accurate to the second, the two times must not be too far in the future because leap seconds affect the count but are only determined about 6 months in advance. With local times a future duration calculation could be off by an entire hour, since legislatures can and do change DST rules at will.
|
||||
<p>
|
||||
If you want to handle wall-clock times in the future, you won't be able (in the general case) to calculate exact durations, for the same reasons described above.
|
||||
<p>
|
||||
If you want accurate calculations with future times, you will have to use TAI or an equivalent, but the mapping from TAI to UTC or local time depends on leap seconds, so you will not have exact agreement with wall-clock time.
|
||||
<p>
|
||||
<H2>Stability, Predictability, and Approximations</H2>
|
||||
|
||||
<p>
|
||||
Here is some underlying theory that helps to explain what's going on.
|
||||
Remember that a temporal type, like any abstract data type (ADT),
|
||||
is a set of values together with operations on those values.
|
||||
<p>
|
||||
<H3>Stability</H3>
|
||||
|
||||
<p>
|
||||
The representation of a type is <i>stable</i> if the bit pattern associated with a given value does not change over time.
|
||||
A type with an unstable representation is unlikely to be of much
|
||||
use to anyone, so we will insist that any temporal library use
|
||||
only stable representations.
|
||||
<p>
|
||||
An operation on a type is stable if the result of applying the operation to a particular operand(s) does not change over time.
|
||||
<p>
|
||||
<H3>Predictability</H3>
|
||||
|
||||
<p>
|
||||
|
||||
Sets are most often classified into two categories: well-defined
|
||||
and ill-defined. Since a type is a set, we can extend these definitions
|
||||
to cover types. For any type T, there must be a predicate
|
||||
<i>is_member( x )</i>
|
||||
which determines whether a value x is a member of type T.
|
||||
This predicate must return <i>true</i>, <i>false</i>, or <i>dont_know</i>.
|
||||
<p>
|
||||
If for all x, is_member( x ) returns either true or false, we
|
||||
say the set T is <i>well-defined</i>.
|
||||
<p>
|
||||
If for any x, is_member( x ) returns dont_know, we say the
|
||||
set T is <i>ill-defined</i>.
|
||||
<p>
|
||||
Those are the rules normally used in math. However,
|
||||
because of the special characteristics of temporal
|
||||
types, it is useful to refine this view and create a third category
|
||||
as follows:
|
||||
<p>
|
||||
For any temporal type T, there must be a predicate <i>is_member( x, t )</i>
|
||||
which determines whether a value x is a member of T.
|
||||
The parameter t represents the time when the predicate is evaluated.
|
||||
For each x<sub>i</sub>, there must be a time t<sub>i</sub> and a value v
|
||||
such that:
|
||||
<ul>
|
||||
<li>v = true or v = false, and
|
||||
<li>for all t < t<sub>i</sub>, is_member( x<sub>i</sub>, t ) returns dont_know, and
|
||||
<li>for all t >= t<sub>i</sub>, is_member( x<sub>i</sub>, t ) returns v.
|
||||
</ul>
|
||||
t<sub>i</sub> is thus the time when we "find out" whether x<sub>i</sub> is a
|
||||
member of T.
|
||||
Now we can define three categories of temporal types:
|
||||
<p>
|
||||
If for all x<sub>i</sub>, t<sub>i</sub> = negative infinity,
|
||||
we say the type T is <i>predictable</i>.
|
||||
<p>
|
||||
If for some x<sub>i</sub>, t<sub>i</sub> = positive infinity,
|
||||
we say the type T is <i>ill-formed</i>.
|
||||
<p>
|
||||
Otherwise we say the type T is <i>unpredictable</i> (this
|
||||
implies that for some x<sub>i</sub>, t<sub>i</sub> is finite).
|
||||
<p>
|
||||
Ill-formed sets are not of much practical use, so we will
|
||||
not discuss them further. In plain english the above
|
||||
simply says that all the values of a predictable type are
|
||||
known ahead of time, but some values of an unpredictable
|
||||
type are not known until some particular time.
|
||||
|
||||
<p>
|
||||
<H3>Stability of Operations</H3>
|
||||
|
||||
<p>
|
||||
Predictable types have a couple of important properties:
|
||||
<UL>
|
||||
<li> there is an order-preserving mapping from their elements onto a set of consecutive integers, and
|
||||
<li> duration operations on their values are stable
|
||||
</UL>
|
||||
The practical effect of this is that duration calculations
|
||||
can be implemented with simple integer subtraction.
|
||||
Examples of predictable types are TAI timepoints and
|
||||
Gregorian dates.
|
||||
<p>
|
||||
Unpredictable types have exactly the opposite properties:
|
||||
<UL>
|
||||
<li> there is no order-preserving mapping from their elements onto a set of consecutive integers, and
|
||||
<li> duration operations on their values are not stable.
|
||||
</UL>
|
||||
Examples of unpredictable types are UTC timepoints and
|
||||
Local Time timepoints.
|
||||
<p>
|
||||
We can refine this a little by saying that a range within
|
||||
an unpredicatable type can be predictable, and operations performed
|
||||
entirely on values within that range will be stable.
|
||||
For example, the range of UTC timepoints from 1970-01-01
|
||||
through the present is predictable, so calculations of durations within that range will be stable.
|
||||
<p>
|
||||
<H3>Approximations</H3>
|
||||
|
||||
<p>
|
||||
These limitations are problematical, because important temporal
|
||||
types like UTC and Local Time are in fact unpredictable, and
|
||||
therefore operations on them are sometimes unstable. Yet as a practical matter we often want to perform this kind of operation, such as computing the duration between two timepoints in the future that are specified in Local Time.
|
||||
<p>
|
||||
The best the library can do is to provide an approximation,
|
||||
which is generally possible and for most purposes will be
|
||||
good enough. Of course the documentation must specify when
|
||||
an answer will be approximate (and thus unstable) and how
|
||||
big the error may be. In many respects calculating with unpredictable sets is analogous to the use of floating point numbers, for which results are expected to only be approximately correct. Calculating with predictable sets would then be
|
||||
analogous to the user of integers, where results are expected
|
||||
to be exact.
|
||||
<p>
|
||||
For situations where exact answers are required or instability cannot be tolerated, the user must
|
||||
be able to specify this, and then the library should throw an
|
||||
exception if the user requests a computation for which an
|
||||
exact, stable answer is not possible.

such as '-', '/', or spaces. In addition, the delimited parsers accept months as either

a numeric value or as a short or long case-insensitive string. For example, the

The class boost::gregorian::date_duration is a simple day count used for arithmetic
|
||||
with <a href="class_date.html">gregorian::date</a>. A duration can be either
|
||||
positive or negative. In addition, date_durations can take on special values such
|
||||
as not_a_date_time. More information on how these special values impact calculation
|
||||
can be found in <a href="Calculations.html">Calculations</a>.

The class boost::gregorian::date_period provides direct representation
|
||||
for ranges between two dates. Periods provide the ability to simplify
|
||||
some types of calculations by simplifying the conditional logic of the
|
||||
program. For example, testing if a date is within an irregular
|
||||
schedule such as a weekend or holiday can be accomplished using
|
||||
collections of date periods. This is facilitated by several methods
|
||||
that allow evaluation if a date_period intersects with another date
|
||||
period, and to generate the period resulting from the intersection.
|
||||
The <a href="exp-period_calc.html">period calculation
|
||||
example</a> provides an example of this.
|
||||
|
||||
|
||||
<p>
|
||||
Date periods used in combination with infinity values have the ability
|
||||
to represent complex concepts such as 'until further notice'.

The library provides for localized stream-based I/O of dates and times.
|
||||
Note that this support is not supported for all compilers. See the
|
||||
<a href="BuildInfo.html">build information</a> page for details.
|
||||
|
||||
<p>
|
||||
To provide for date output (and eventually input) the library uses a specialized
|
||||
facet class that provides the month name strings (both short and long -- eg: Jan, January),
|
||||
order of the date output (year-month-day, day-month-year, etc), and the delimeters
|
||||
between various parts of the date. To localize the date the process entails constructing
|
||||
the facet with the desired parameters, calling imbue on the stream, and then streaming
|
||||
the date.
|
||||
<p>
|
||||
By default, the date operator << uses the following default strings:
|
||||
<div class="fragment"><pre>
|
||||
us_short_month_names={"Jan","Feb","Mar","Apr","May","Jun","Jul",
|
||||
"Aug","Sep","Oct","Nov","Dec", "NAD"};
|
||||
us_long_month_names={"January","February","March","April","May","June","July",
|
||||
"August","September","October","November","December","Not-A-Date"};
|
||||
us_special_value_names={"Not-A-Date","-infinity", "+infinity"};
|
||||
us_long_weekday_names={"Sunday", "Monday", "Tuesday","Wenesday", "Thursday", "Friday", "Saturday"};
|
||||
us_short_weekday_names={"Sun", "Mon", "Tue","Wed", "Thu", "Fri", "Sat"};
|
||||
</pre></div>
|
||||
|
||||
<p>
|
||||
The following example shows how to output dates using German names first with short month names
|
||||
and then with long month names.

The class boost::gregorian::gregorian_calendar implements the functions
|
||||
necessary to create the gregorian date system. It converts to
|
||||
the year-month-day form of a date to a day number representation
|
||||
and back.
|
||||
|
||||
<p>
|
||||
For most purposes this class is simply accessed by
|
||||
<a href="class_date.html">gregorian::date</a> and is not used directly
|
||||
by the user. However, there are useful functions that
|
||||
might be of use such as the <font class="func">end_of_month_day</font>
|
||||
function.
|
||||
<p>
|
||||
The <a href="exp-print_month.html">print month</a> example demonstrates this.

The class boost::posix_time::ptime is the primary interface for time
|
||||
point manipulation. In general, the ptime class is immutable once
|
||||
constructed although it does allow assignment.
|
||||
|
||||
<p>
|
||||
Class ptime is dependent on <a href="class_date.html">gregorian::date</a>
|
||||
for the interface to the date portion of a time point.
|
||||
<p>
|
||||
Other techniques for creating times include <a href="time_iterators.html">time iterators</a>.

<h2><a name="intro">Introduction</a></h2>
|

|

<p>
|
||||
The class boost::posix_time::time_duration the base type responsible for
|
||||
representing a length of time. A duration can be either positive or
|
||||
negative. The general time_duration class provides a constructor that
|
||||
takes a count of the number of hours, minutes, seconds, and fractional
|
||||
seconds count as shown in the code fragment below. The resolution
|
||||
of the time_duration is configureable at compile time. See
|
||||
<a href="BuildInfo.html">Build-Compiler Information</a> for more
|
||||
information.
|
||||
|
||||
|
||||
<div class="fragment"><pre>
|
||||
|
||||
<font class="keyword">using namespace</font> boost::posix_time;
|
||||
|
||||
time_duration td(1,2,3,4); <font class="comment">//01:02:03.000000004 when resolution is nano seconds</font>
|
||||
time_duration td(1,2,3,4); <font class="comment">//01:02:03.000004 when resolution is micro seconds</font>
|
||||
</pre></div>
|
||||
|
||||
<p>
|
||||
Several small helper classes that derive from a base time_duration, as
|
||||
shown below, to adjust for different resolutions. These classes can
|
||||
shorten code and make the intent clearer.
|
||||
|
||||
<p>
|
||||
<img align="middle" src="time_duration_inherit.png" alt="inherit">
|
||||
<p>
|
||||
As an example:
|
||||
<div class="fragment"><pre>
|
||||
|
||||
<font class="keyword">using namespace</font> boost::posix_time;
|
||||
|
||||
time_duration td = hours(1) + seconds(10); <font class="comment">//01:00:01</font>
|
||||
td = hours(1) + nanosec(5); <font class="comment">//01:00:00.000000005</font>
|
||||
</pre></div>
|
||||
<p>
|
||||
Note that the existence of the higher resolution classes (eg: nanosec)
|
||||
depends on the installation of the library. See
|
||||
<a href="BuildInfo.html">Build-Compiler Information</a> for more
|
||||
information.

Date algorithms or generators are tools for generating other dates or schedules of dates. A generator function starts with some part of a date such as a month and day and is supplied another part to then generate a concrete date. This allows the programmer to represent concepts such as "The first Sunday in February" and then create a concrete set of dates when provided with one or more years.

Date iterators provide a standard mechanism for iteration through dates.
|
||||
Date iterators are are similar to <a href="http://www.sgi.com/tech/stl/BidirectionalIterator.html">Bidirectional Iterators</a>
|
||||
and can be used to populate collections with dates and other date generation
|
||||
tasks. For example, the <a href="exp-print_month.html">print month</a> example iterates through all the days in a month and prints them.
|
||||
<p>
|
||||
All of the iterators here derive from boost::gregorian::date_iterator and provide a
|
||||
various comparison operations against dates including equal, not equal, less, lees equal,
|
||||
greater, and greater equal.

<h2><a name="intro">Introduction</a></h2>
|
||||
|
||||
<p>
|
||||
The gregorian date system provides a date programming system based the
|
||||
Gregorian Calendar. The first introduction of the Gregorian calendar was
|
||||
in 1582 to fix an error in the Julian Calendar. However, many local
|
||||
jurisdictions did not adopt this change until much later. Thus there
|
||||
is potential confusion with historical dates.
|
||||
<p>
|
||||
The implemented calendar is a "propleptic Gregorian calendar" which extends
|
||||
dates back prior to the Gregorian Calendar's first adoption in 1582.
|
||||
The current implementation supports dates in the range
|
||||
1400-Jan-01 to 10000-Jan-01. Many references will represent dates
|
||||
prior to 1582 using the Julian Calendar, so caution is in order if
|
||||
accurate calculations are required on historic
|
||||
dates.
|
||||
See <A href="http://emr.cs.iit.edu/home/reingold/calendar-book/second-edition/">Calendrical Calculations</A> by Reingold & Dershowitz for more details.
|
||||
Date information from Calendrical Calculations has been used to cross-test
|
||||
the correctness of the Gregorian calendar implementation.
|
||||
<p>
|
||||
All types for the gregorian system are found in namespace boost::gregorian.
|
||||
The library supports a convenience header <font class="el">boost/date_time/gregorian/gregorian_types.hpp</font> that will include all the classes of the
|
||||
library with no input/output dependency.
|
||||
Another header <font class="el">boost/date_time/gregorian/gregorian.hpp</font> will include the types and the input/output code.
|
||||
<p>
|
||||
The class <a href="class_date.html">boost::gregorian::date</a> is the primary
|
||||
temporal type for users. If you are interested in learning about writing
|
||||
programs do specialized date calculations such as finding the
|
||||
"first sunday in april" see the
|
||||
<a href="date_algorithms.html">date generators and algorithms page</a>.

<h2><a name="intro">Introduction</a></h2>
|
||||
|
||||
<p>
|
||||
A set of date-time libraries based on generic programming concepts.
|
||||
<p>
|
||||
<h2><a name="motivation">Motivation</a></h2>
|
||||
|
||||
<p>
|
||||
The motivation for this library comes from working with and helping build several date-time libraries on several projects. Date-time libraries provide fundamental infrastructure for most development projects. However, most of them have limitations in their ability to calculate, format, convert, or perform some other functionality. For example, most libraries do not correctly handle leap seconds, provide concepts such as infinity, or provide the ability to use high resolution or network time sources. These libraries also tend to be rigid in their representation of dates and times. Thus customized policies for a project or subproject are not possible.
|
||||
<p>
|
||||
Programming with dates and times should be almost as simple and natural as programming with strings and integers. Applications with lots of temporal logic can be radically simplified by having a robust set of operators and calculation capabilities. Classes should provide the ability to compare dates and times, add lengths or time durations, retrieve dates and times from clocks, and work naturally with date and time intervals.
|
||||
<p>
|
||||
<h2><a name="usage">Usage Examples</a></h2>
|
||||
|
||||
<p>
|
||||
The following shows examples of the sorts of code that can be written using the gregorian date system. See <a href="gregorian.html">Date Programming</a> for more details.
|
||||
<p>
|
||||
<div class="fragment"><pre> <font class="keyword">using</font> <font class="keyword">namespace </font>boost::gregorian;
|
||||
date weekstart(2002,Feb,1);
|
||||
date weekend (2002,Feb,7);
|
||||
date_duration fiveDays(5);
|
||||
date d3 = d1 + fiveDays;
|
||||
date today = day_clock::local_day();
|
||||
<font class="keywordflow">if</font> (d3 >= today) {} <font class="comment">//date comparison operators</font>
|
||||

|
||||
<h2><a name="domain">Domain Concepts</a></h2>
|
||||
<p>
|
||||
The date time domain is rich in terminology and problems. The following is a brief introduction to the concepts you will find reflected in the library.
|
||||
<p>
|
||||
|
||||
The library supports 3 basic temporal types:
|
||||
<UL>
|
||||
<li> <font class="bold">Time Point</font> -- Specifier for a location in the time continuum.
|
||||
<li> <font class="bold">Time Duration</font> -- A length of time unattached to any point on the time continuum.
|
||||
<li> <font class="bold">Time Interval</font> -- A duration of time attached to a specific point in the time continuum. Also known as a time period.
|
||||
</UL>
|
||||
|
||||
Each of these temporal types has a <font class="bold">Resolution</font> which is defined by the smallest representable duration. A <font class="bold">Time system</font> provides all these categories of temporal types as well as the rules for labeling and calculating with time points. <font class="bold">Calendar Systems</font> are simply time systems with a maximum resolution of one day. The <font class="bold">Gregorian</font> system is the most widely used calendar system today (the ISO system is basically a derivative of this). However, there are many other calendar systems as well. <font class="bold">UTC (Coordinated Universal Time)</font> is a widely used civil time system. UTC is adjusted for earth rotation at longitude 0 by the use of leap seconds (This is not predictable, only as necessary). Most <font class="bold">local time</font> systems are based on UTC but are also adjusted for earth rotation so that daylight hours are similar everywhere. In addition, some local times include <font class="bold">daylight savings time (DST)</font> adjustments to shift the daylight hours during the summer.
|
||||
|
||||
<p>
|
||||
A <font class="bold">Clock Device</font> is software component (tied to some hardware) that provides the current date or time with respect to a time system. A clock can measure the current time to a known resolution which may be higher or lower than a particular time representation.
|
||||
|
||||
<p>
|
||||
The library provides support for calculating with dates and times. However, time calculations are not quite the same as calculating with integers. If you are serious about the accuracy of your time calculations need to read about <a href="Tradeoffs.html">Stability, Predictability, and Approximations</a>.

||||

||||

<p>
|
||||
|
||||
<p>
|
||||
<h2><a name="test">Tests</a></h2>
|
||||
|
||||
<p>
|
||||
The library provides a large number of tests in the
|
||||
<pre>
|
||||
libs/date_time/test
|
||||
libs/date_time/test/gregorian
|
||||
libs/date_time/test/posix_time
|
||||
</pre>
|
||||
<p>
|
||||
directories. Building and executing these tests assures that the installation is correct and that the library is functioning correctly. In addition, these tests facilitate the porting to new compilers. Finally, the tests provide examples of many functions not explicitly described in the usage examples.
|
||||
<p>
|
||||
|
||||
<h2><a name="design">Design and Extensions</a></h2>
|
||||
<p>
|
||||
A large part of the genesis of this library has been the observation that
|
||||
few date-time libraries are built in a fashion that allows customization
|
||||
and extension. A typical example, the calendar logic is built directly
|
||||
into the date class. Or the clock retrieval functions are built directly
|
||||
into the time class. These design decisions usually make it impossible to
|
||||
extend or change the library behavior. At a more fundamental level,
|
||||
there are usually assumptions about the resolution of time representation
|
||||
or the gregorian calendar.
|
||||
<p>
|
||||
Often times, the result is that a project must settle for a less
|
||||
than complete library because of a requirement for high resolution
|
||||
time representation or other assumptions that do not match the
|
||||
implementation of the library. This is extremely unfortunate because
|
||||
development of a library of this sort is far from a trivial task.
|
||||
<p>
|
||||
While the design is far from perfect the current design is far
|
||||
more flexible than any date-time library the author is aware of. It
|
||||
is expected that the various aspects of extensibility will be better
|
||||
documented in future versions. Information about the design goals
|
||||
of the library is <a href="DesignGoals.html">summarized here.</a>
|
||||

||||

<h2><a name="intro">Introduction</a></h2>
|
||||
<p>
|
||||
A frequent problem in time representation is the conversion between
|
||||
various local time systems. In general this is accomplished by
|
||||
using a reference time system. The reference time system is typically
|
||||
UTC.
|
||||
<p>
|
||||
Since the posix_time system does no internal time adjustment it
|
||||
can be used to represent both local times and UTC times. However,
|
||||
the user is currently left to handle conversions and time zone
|
||||
knowledge explicitly.
|
||||
<p>
|
||||
The library offers two different ways to perform UTC to local conversions.
|
||||
The first is using the time zone settings of the computer. This is
|
||||
a useful solution for converting a UTC time for a user machine. This
|
||||
approach depends on the ctime API and will provide incorrect results
|
||||
if the environment is set incorrectly.
|
||||
The other approach allows conversion from any zone to UTC and back
|
||||
independent of the settings of the time zone settings of the
|
||||
computer. The <a href="exp-local_utc_conversion.html">local utc conversion example</a>
|
||||
demonstrates both of these techniques.

Time iterators provide a mechanism for iteration through times. Time iterators are similar to <a href="http://www.sgi.com/tech/stl/BidirectionalIterator.html">Bidirectional Iterators</a>.
|
||||
However, time_iterators are different than standard iterators in that there is no underlying sequence, just a calculation function. In addition, time_iterators are directly comparable against instances of <a href="class_ptime.html">class ptime</a>. Thus a second iterator for the end point of the iteration is not required, but rather a point in time can be used directly. For example, the following code iterates using a 15 minute iteration interval. The <a href="exp-print_hours.html">print hours</a> example also illustrates the use of the time_iterator.
