0.10 2003-04-19 (the "I'm sure the new regime will be spiffy" release)
[IMPROVEMENTS]
- Added Tigre language module. Contributed by Daniel Yacob.
- DateTime::Duration objects now overload multiplication. Implemented
by Flavio Glock.
- Added support for nanoseconds in DateTime.pm and DateTime::Duration.
Implemented by Flavio Glock.
- Added complete support for leap seconds (through use of
DateTime::LeapSecond). Mostly implemented by Flavio Glock.
[ BACKWARDS INCOMPATIBILTIES ]
- Because of the addition of leap seconds to the mix, we are now
forced to handle seconds separately from minutes when doing date math.
This means that several aspects of the DateTime::Duration API have
changed. Specifically:
-- There is now an additional delta_minutes() method.
-- The hash returned by the deltas() method now includes a "minutes" key.
-- The seconds delta may be greater than 59.
-- The seconds() method may return a number greater than 59.
0.09 2003-04-05 (the "liberation through violence" release)
[IMPROVEMENTS]
- As requested by numerous people, there is now a pure Perl
implementation of DateTime.pm included with this distribution. If you
don't have a C compiler it will be used instead of the XS
implementation.
- Document how floating time zones are handling in comparisons, and
add the compare_ignore_floating method. Based on a patch from Eugene
van der Pijll.
- Allow from_epoch(), now(), and today() to accept a time_zone
parameter. Based on suggestions from Tim Bunce and Joshua Hoblitt.
- Allow extraction of AM/PM string list from DateTime::Language classes.
- Added quarter() and day_of_quarter() methods. Based on a patch from
Tim Allwine.
[BUG FIXES]
- If a datetime had the floating timezone and then set_time_zone was
used to set it to something else, the internal UTC time of the object
was not changed, meaning that its offset could be calculated
incorrectly. Patch by Eugene van der Pijll.
- If datetime math was done with hours, minutes, or seconds, the
return value of ->epoch would be wrong after this. Based on report
and patch from Iain Truskett.
0.08 2003-03-21 (the "anti-war" release)
[IMPROVEMENTS]
- All set/modify methods now return the datetime object, in order to
make method chaining possible. Patch by Iain Truskett.
- The _greg2rd and _rd2greg methods have been renamed _ymd2rd and
_rd2ymd, so as to make them look more normal when used in subclasses.
- Added a truncate() method. Suggested by Flavio Glock.
- Added Swedish language module. Contributed by Christian Hansen.
- Added language modules for Afar, Amharic, Gedeo, Oromo, Sidama,
Somali, and Tigrinya (Eritrean and Ethiopian), all courtesy of Daniel
Yacob.
- Various doc improvements, including a section on invalid local times.
[BUG FIXES]
- The week() method was wrong for many dates. Reported by Christian
Hansen.
- The last_day_of_month() method had the DateTime class hard-coded in
it. Reported by Eugene van der Pijll.
- Fixed a bug when comparing a datetime object to infinity (or
negative infinity). Fixed by Flavio Glock.
- Date math has been fixed so that it affects the _local_ times. This
means that sometimes 1 day is not equal to 24 hours when the
addition/subtraction crosses over a Daylight Saving Time change. See
the "How Date Math is Done" section of the docs for more details.
[BACKWARDS INCOMPATIBILITIES]
- Objects constructed via the new() method now have a "floating" time
zone by default, instead of using the "local" time zone. This is just
simpler to deal with, and for code where time zones are unimportant,
this is the most appropriate default.
0.07 2003-02-26
[IMPROVEMENTS]
- Added a small hack to the compare() method so that this module can
be used with Set::Infinite.
- Changed compare so that it can be used to compare two objects from
different calendars that conform to the DateTime::Calendar interface.
- Added explanation of exactly what calendar this module represents
("proleptic Gregorian calendar") to docs.
- Added a Spanish language DateTime::Language subclass. Implemented
by Flavio S. Glock.
- Added support for specifying a language by ISO code ("en" or
"pt-br") as well as the subclass name. Based on a patch from Eric
Cholet.
- Revamped the externally visible DateTime::Language API.
- Objects created via the from_object() method are set to the time
zone of the object from which they were created, if it has one, or UTC
otherwise.
[BUG FIXES]
- The from_object() method was broken because it retrieved a UTC
datetime from the object passed in, and then created a new DateTime
object using that UTC time as a _local_ time.
[BACKWARDS INCOMPATIBILITIES]
- Removed stringification overloading. Having this in place made it
impossible to create a strack trace in much of the time zone code.
- Renamed the DateTime::Language->subclasses method as languages.
- It is no longer possible to directly instantiate a
DateTime::Language subclass, instead use:
my $en = DateTime::Language->new( language => 'English' );
- The from_object() method no longer accepts a "time_zone" parameter.
0.06 2003-02-16
- The docs said that there was no year 0 in the Gregorian calendar,
but that was wrong. The year() method can now return 0. The year_0()
method has been removed.
- Added jd() and mjd() methods.
- Re-implemented some of the core code in XS for speed.
0.05 2003-02-13
- Fix handling and reporting of epoch times. Epoch times are, by
definition, UTC times, so any time created from an epoch should always
have its time zone set to "UTC". This can be changed after the object
is created. Similarly, value returned by the epoch() method needs to
be based on the object's UTC time, not it's local time. Bug reported
by Kellan Elliott-McCrea.
- Change year_0 so that -1 BCE is 0, not 1 CE. This corresponds to
astronomical years.
- Change ymd, dmy, mdy, and iso8601 to use Gregorian years (..., -2,
-1, 1, 2, ... ) as opposed to astronomical years. Also make sure all
negative years are formatted as 4 digits.
0.04 2003-02-10
- Explicitly set time zone for objects created during tests.
0.03 2003-02-09
- Giving a language parameter to a constructor method didn't load the
language class.
- Test that all language classes are at least loadable.
- Added Brazilian (not quite a language ;) and Danish, again stolen
from Graham Barr's TimeDate suite.
- Added is_dst method. Requested by Matt Sergeant.
0.02 2003-02-09
- Fixed a bug in calculating day of year in leap years (it was +1 off
starting in February). Reported by Matt Sergeant.
- Subtracting one datetime from another was broken in most cases.
Improved the tests for this quite a bit. Reported by Eric Cholet.
- Made the version number a non-dev-release so it's visible when
CPAN.pm tries to install it as a prereq for something else.
0.01_00 2003-02-04
- The first alpha release. This module draws on Date::ICal for much
of its internals, so it has more history than a normal alpha release.
