NAME

Date::Manip::Changes6 - changes in Date::Manip 6.xx

SYNOPSIS

This describes the changes made to the Date::Manip module in the 6.xx series of releases. Major changes are marked with asterisks (*).

For the most part, Date::Manip has remained backward compatible at every release, but occasionally, a change is made which is backward incompatible. These are marked with an exclamation mark (!).

Version 6.12

(!) IntCharSet config variable deprecated

With better support for international character sets, the old IntCharSet config variable (which was a bandaid at best) is deprecated. Currently, the functionality still exists, but it will be removed at some point.

New features

Added the Encoding config variable.

Now supports parsing the EXIF date format. Rhesa Rozendaal

Bug fixes

Fixed Build.PL to not require perl 5.010 since the distribution as a whole does not require that (and I want that fact to be in META.yml).

Fixed a bug where the Date::Manip::Date::set method was broken when setting individual fields. Helmut A. Bender

Fixed a bug where set didn't work in Date::Manip::Delta. Patch provided in RT 59096.

Time zone fixes

Newest zoneinfo data (tzdata 2010m)

Language fixes

(*) Converted all language files to UTF-8 and added rudimentary support for character encodings. Some assistance by Stephen Ostermiller.

Fixed problem in Polish, Dutch. Stephen Ostermiller

Extended support for 'nth' up to 53rd. Paco Regodon

Added some corrections to German. Dieter Lange

Documentation fixes

Clarified Date::Manip::Recur documentation based on RT 59132.

Version 6.11 (2010-04-30)

Bug fixes

Fixed a problem in Build.PL that had an incorrect module requirement.

Version 6.10 (2010-04-29)

(*) Combined 5.xx and 6.xx releases into one distribution

Because the automatic module management tools cpan/cpanp would try to upgrade Date::Manip to the most recent version, and the most recent version will only work if perl 5.10.0 or higher is installed, both the 5.xx and 6.xx releases are now combined into a single distribution.

This is described more fully in the Date::Manip::Problems document.

(!) Zones specified by offset

In all operations involving time zones, the time zone must be determined. By default, it would take all of the information available (date, ISDST, etc.) and determine the most likely time zone. It would take every time zone that matched each piece of information, starting with those that matched in a standard time followed by those that matched in a daylight saving time.

When zones are specified by an offset, a standard time would always match since there are standard time zones that match all year long (the military time zones A-Z and the standard time zones of the form Etc/GMT+01). As a result, a daylight saving time match would never occur.

Since (if the date falls during a daylight saving time period) you usually want to use a time zone that has that offset in daylight saving time, the default is now to check daylight saving time zones first, followed by standard times.

See the Date::Manip::TZ manual (under the zone method) for more information.

Bug fixes

Fixed a bug where Date_ConvTZ not working correctly with time zones specified by offset. Chris Butler

Fixed a bug where business mode calculations involving minutes was not handled correctly. Damien Moore

Fixed a bug where business mode calculations failed in some cases. RT 56638

Time zone fixes

Newest zoneinfo data (tzdata 2010i)

Changed Date::Manip::TZ::zone so "dst" is sometimes the default $dstflag. Based on the bug report by Chris Butler.

OpenUNIX puts a colon at the start of some time zones. It's removed. Jean Hassler

Test fixes

Converted tests to Test::Inter

Documentation fixes

Fixed a documentation bug in Date::Manip::TZ where "stdonly" was listed as the default value for $dstflag, but in actuality, "std" is the default.

Version 6.07 (2010-02-05)

Bug fixes

Fixed bug in Date_TimeZone where it wasn't returning the time zone. Robert Eden

Version 6.06 (2010-02-05)

Bug fixes

Minor bug where %Z printf format didn't always work.

Added support for 5pm back in (it was omitted accidentally). Mark Kennedy

Fixed a minor warning. Morten Bjoernsvik

Some additional speedups.

Time zone fixes

Newest zoneinfo data (tzdata 2010b)

Added dm_zdump example script.

Improved TZ::periods functionality

Fixed bug in Date_ConvTZ where empty values weren't defaulting to local time zone. Robert Eden

Fixed a couple of problems in the generated time zones for some odd cases (America/Resolute and Asia/Tehran).

Version 6.05 (2009-12-09)

(!) %z format

In Date::Manip 5.xx, the %z format in UnixDate printed the offset in the form -0500. In 6.00, I changed that to -05:00:00, but this broke RFC 822 compliance.

I've changed %z back to -0500, and introduced a new format (%N) which returns -05:00:00.

Incidentally, this is the LAST unused letter, so I am now going to have to either stop adding formats, or add some extended format syntax. Not sure yet which, but this may involve a backwards incompatible change in the future.

(*) Significant speedups.

Thanks to Moritz Lenz and BrowserUK on perlmonks for suggestions (and a number of other people on perlmonks for suggestions that I did not end up using, but which provided a great discussion).

Bug fixes

Fixed a bug in parse_date where the current time was getting used instead of the documented 00:00:00

Bug fix where DateCalc didn't work with $mode in some cases.

Fixed Makefile.PL/Build.PL to handle Win32::TieRegistry requirement.

Changed %z printf behavior back to 5.xx and added %N format. Gilles Lamiral

Added dm_date example script.

Time zone fixes

Fixed bug where non-English Windows versions didn't get the time zone. Thanks to Rene Schickbauer for testing.

Test fixes

Reduced the precision of 1 test to avoid a rounding difference when using a perl compiled with uselongdouble. Andreas Koenig

Version 6.04 (2009-11-25)

Bug fixes

Fixed a bug where events were not interpreted in the correct time zone if SetDate/ForceDate used.

Version 6.03 (2009-11-24)

Bug fixes

Corrects a backward incompatibility with UnixDate. Rene Schickbauer

Test fixes

A couple more corrections to the tests.

Version 6.02 (2009-11-24)

Bug fixes

Disabled curr_zone_methods when taint checking on. I believe that Date::Manip is completely taint friendly at this point.

Test fixes

A quick fix to make sure that the tests run correctly in other time zones.

Version 6.01 (2009-11-23)

Bug fixes

(*) Fixed a bug where dates were sometimes getting the wrong time zone when SetDate/ForceDate in effect.

Version 6.00 (2009-11-23)

Date::Manip 6.00 is a total rethink of the module, and a nearly complete rewrite. Please refer to the Date::Manip::Changes5to6 document for a list of incompatible changes.

Reorganization

(*) Massive reorganization and near total rewrite.

(*) Broke into several smaller modules

New Features

(*) Full time zone support (using tzdata 2009s)

Added some functionality (suggested by James Elson to improve setting the "current time". Done with the ForceDate config variable.

(*) Converted languages to YAML for much easier maintenance. Patch and suggestion provided by Evan Carroll

Added much better formats for deltas. Suggested by Jim Hranicky.

Borrowed the _FindWindowsTZName function from the DateTime-TimeZone module.

Added SetDate config variable (based on a suggestion by Christian Campbell).

Added parse_format which was first suggested by Kim Ryan.

Other changes

Several config variables deprecated

Thanks to Jonathan Hogue for helping test Windows additions.

Bug fixes (correctly problems in the 5.xx releases)

Fixed a bug where "YYtoYYYY=c" wouldn't work.

VMS bugfix to not call `date` command. Lane

New Year's Day defined using a recurrence which might push the observed day to the previous year was broken. Reported by Alan Burlison

Language fixes

Fixed typo in Turkish translation.

Spelling fix in Dutch. Bart Van Loon

Additional credits

I have received many suggestions over time which were automatically handled during the 6.00 rewrite. Although the changes weren't made because of the suggestions specifically, I wanted to acknowledge them since I appreciate the suggestions.

I believe the first person to suggest writing Date::Manip as an OO module was Eduard Derksen.

Delta_Format initialization done outside of the function. Eric Boehm

Added $subtract to calculation routines. First suggested by Steve Berlage.

Added ability to set individual parts of the date (Date::Manip::Date::set). First suggested by Martin Thurn.

UnixDate (i.e. Date::Manip::Date::printf) only calculates formats when they are needed. Eduard Derksen

Parsing will skip some date/time formats if requested. This was first suggested by Eduard Derksen.

It has been suggested several times to support multiple languages, multiple config files, or multiple sets of Date_Init options. These suggestions (by Meng Fang, Ed Avis, Christian Campbell, and perhaps others) were at the back of my mind as I developed the Date::Manip::Base class.

The regular expressions are all i18n friendly in anticipation of much better support for localization. First suggested by Alex Kapranoff.

Parsing a date ('today', 'Monday') gives a time of '00:00:00'. Suggested by Mark Aitchison.
