1.2000 2011-01-02

• Release 1.1902 as a stable version without any further chances.

1.1902 2010-12-16 TRIAL RELEASE

• Merge all changes from blead perl.
• Try to restore compatibility with older perls, which don't have a 64bit capable localtime/gmtime.

1.1901 2008-11-01

• Test fixes only. The tests planned the wrong number of tests on 32-bit platforms, causing failures.

1.19 2008-11-01

• The calculation of the maximum integer size was using $Config{intsize} when it should use $Config{ivsize}. Apparently on a 64-bit platform intsize can be 4 when ivsize is 8. Based on a patch from Jan Dubois.

1.18 2007-10-31

• Added pod and pod coverage tests.
• Doing a new release to provide a conformant META.yml file.
• This release contains no code changes from 1.17.

1.17 2007-01-25

• I made the same test count mistake as was in 1.14 again. This release fixes the test count (again) when running on a system that doesn't support negative epochs (like Win32). Patched by Kenichi Ishigaki (again).

1.16 2007-01-23

• The leap year fix in 1.14 was pretty broken, as it checked after converting the year to Perl's internal (year - 1900) format.

1.15 2007-01-22

• Fix Local.t test count when running on a system that doesn't support negative epochs (like Win32). Patched by Kenichi Ishigaki.

1.14 2007-01-21

• Fixed leap year check to produce the right answer for years outside of the 32-bit epoch range (such as 1900 and 2100). See rt.perl.org #31241. Reported by Nathan Zook.

1.13 2006-08-09

• Switched to using Test::More for the tests.
• Fixed a bug that occurred around the DST change for Europe/London (and probably other time zones with a positive UTC offset). If given, the hour immediately after the change (2:00 AM for Europe/London), then the returned epoch was 3600 seconds too large. Reported by Roger Picton. See RT #11662.

1.12_01 2006-03-31

• Reverted changes from 1.07_90 that attempted to extend range of allowable epoch values around edge cases. It turns out that this was causing integer overflows
• In one error case, the module could warn and then croak. I changed it to simply croak with the whole message. Based on a patch by Michael Schwern from rt.perl.org #36268.
• Removed the code from the docs that implied that the *_nocheck variants were created for doing date math. They're just for speeding things up when you have known valid data. If you pass them invalid data, you'll probably get an incorrect answer. See #31421 on rt.perl.org for discussion.

1.12 2005-12-18

• Explicitly turn off negative epoch testing on VMS. Change #24310 from bleadperl, Craig Berry.
• In the test suite when checking on whether negative epochs are allowed, use 3 days before the epoch as a test, because just one hour before may give false positives (for example on Win32 with the Borland compiler).
• Reverted an earlier change that slightly extended the range of values for which timelocal worked (by about a day in either direction) because it could cause an incorrect answer for certain epoch values on the date of a DST change. Reported by Gisle Aas.

1.11 2005-02-09

• Try to make detection of supported epoch range a little smarter. The detection was allowing negative epochs on Win32 but apparently this doesn't work, and trying to pass a pre-epoch date in just causes a lot of warnings. This silences warnings during the tests on windows.

1.10 2004-04-20

• Fix compilation failure with older Test.pm (including the versions shipped with 5.6.1 and earlier perls). Ticket #6079 on rt.cpan.org. Patch by somebody who didn't give their name on rt.cpan.org ;)

1.09 2004-04-07

• Fixed a bug in the test suite that led to timegm not getting tested properly, and timelocal getting tested twice for the same values.

1.08 2004-04-07

• Changed occurences of "UTC" to "GMT" in order to agree with POSIX, which defines the epoch in terms of GMT.
• Documented the behavior of timelocal() when given a local time that does not exist (due to a DST change). Suggested by Nick Ing-Simmons.
• Don't expect edge case tests to pass on AIX 4.3, since the OS is obselete. Patch from core passed on my H. Merijn Brand.

1.07_94 2003-12-11

• More changes from Henrik Gulbrandsen to make sure that very large negative epoch values are handled properly on platforms that can handle negative epoch values at all.
• Make sure that we really do always return the earliest of two local times when DST makes conversion from GMT to local time ambiguous. Again by Henrik.
• Fix a bug that could have occurred if the maximum or minimum integer size on a platform was divisible by 86,400. Also by Henrik.

1.07_93 2003-07-23

• Henrik's code explicitly didn't work with negative epoch values, which is not good. Now we assume that they are allowed, except on MacOS, which is known to use an unsigned int for time_t.
• Document that dates before the epoch should work on systems which support negative epoch values, but that we can't test them because we don't know which systems support this.

1.07_92 2003-07-23

• Removed tests which relied on the zoneinfo database to be up to date and accurate in order to pass, since we have absolutely no control over this whatsoever. I hate external dependencies.

1.07_91 2003-07-22

• Henrik refined his edge case fix to work on Win32, which apparently dislikes large negative signed ints. Tests now pass on Win32. More testing on other platforms is appreciated.
• Documented Time::Local's behavior when timelocal is called with an ambiguous local time. Some local times occur twice on the same day because a DST change causes the clock to move backwards one hour earlier. See "Ambiguous Local Times" in the docs for more details. Closes perlbug 7822.
• Removed the statement under "BUGS" that the proclivity to croak() is probably a bug. It's not a bug, and it sure isn't going to change at this point in time, anyway!

1.07_90 2003-07-15

• Fixed behavior for edge cases like timegm(gmtime(0x7FFF_FFFF)), which should work even on platforms where time_t is signed. Patch from Henrik Gulbrandsen.

1.07 2003-06-10

• Set INSTALLDIRS=perl in Makefile.PL, as suggested by Michael Schwern, who heard it from Sergio Brandano.

1.06 2003-06-04

• A bug in the handling of negative offsets from UTC could lead to the return of invalid times during a DST transition. This is from a patch by Dave Mitchell currently in bleadperl. See http://bugs6.perl.org/rt2/Ticket/Display.html?id=19393 for details. Thanks to Rafael Garcia-Suarez for pointing this out to me.
• Updated the AUTHORS section to include the actual authors. Thanks to Graham Barr for telling me who there are.
• Added SUPPORT section which tells people to use bugs.perl.org or perlbug, since I read p5p and I want to make sure that the core and this code stay in sync.
• Clarified docs to say that dates before the system's epoch may or may not work, because POSIX only requires support for positive time_t values.

1.05 2003-06-03

This version is nearly identical to version 1.04, which is included in the Perl core, but it removes the use of "our" in order to make the code backwards compatible with Perl 5.00503. It probably works with earlier versions of Perl as well, but I don't have anything earlier than 5.00503 installed.

Changes made from the core version include:

• Packaged for distribution on CPAN.
• Added an AUTHOR section to the docs.
• Clarified some points in the docs, particularly the fact that this module uses the local system's epoch, not the Unix epoch, contrary to what the documentation suggests.
• Disabled tests for timelocal.pl Perl4 library since it's not included in standalone distribution.
