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 6.61 (planned 2017-12-01)

VERSION 6.60 (planned 2017-09-01)

       Bug fixes
           Fixed  a bug where if a recurrence had no interval, start and end dates passed in to the dates method
           would not work.  PJ-DSI-DevOps (GitHub #12).

       Documentation fixes
           Clarified Date::Manip::TZ::all_periods.  Based on discussion with Peter Pfannenschmid.

VERSION 6.59 (2017-06-01)

       Time zone fixes
           Newest zoneinfo data (tzdata 2017b)

       Documentation fixes
           Improved some of the documentation.

VERSION 6.58 (2017-03-01)

       Better support for $mode in DateCalc.
           DateCalc (in DM6) did not support all values for $mode.  Now it does.

       Bug fixes
           Parsing a date like 01/02/2016 and calling printf with %e gave '02' instead of ' 2'.  RT 119787.

           Fixed a problem where the tzdata method of determining the timezone  was  producing  an  error  which
           wasn't correct.  John (GitHub #8)

       Time zone fixes
           Newest zoneinfo data (tzdata 2017a)

VERSION 6.57 (2016-12-01)

       Time zone fixes
           Newest zoneinfo data (tzdata 2016j)

       Test fixes
           A faulty test was failing in a few places.  RT 118705

           Another  test was failing due to a perl bug that popped up in 5.25.7.  Tweaked the test to bypass the
           bug.  RT 118862

VERSION 6.56 (2016-09-09)

       Test fixes
           A faulty test was failing most places.  New release to correct that problem.  RT 117404

VERSION 6.55 (2016-09-01)

       Fixed bug where $::TZ wasn't used
           The $::TZ variable was not getting interpreted correctly when searching for a timezone.  RT 114949.

       Fixed bug where recurrences were not parsed correctly
           Passing in incorrect values for a field was not trapped in all cases and it  led  to  problems.   All
           values passed in to a recurrence are now correctly checked.  Albert Hilazo (GitHub #7).

       Fixed a bug in some methods of creating new objects
           Some  methods  of  creating  new objects based on existing objects did not correctly use the existing
           object.  Bug has never been reported, but was discovered when adding tests to get 100% coverage.

       Time zone fixes
           Newest zoneinfo data (tzdata 2016f)

       Test fixes
           Added a number of new tests based on Devel::Cover.

VERSION 6.54 (2016-05-31)

       Deprecation of Date::Manip 5.xx tests
           By default, the Date::Manip 5.xx tests will no longer run.  Changes to the timezone  data  can  cause
           failures.   Since  Date::Manip 5.xx is no longer supported in any way, these tests will no longer run
           on a system where 6.xx can be run.  Richard Jelinek.

       Deprecation of TZ postponed
           The deprecation of the TZ variable has been postponed to March 2017.  I decided that 1 year  was  not
           enough  notice (especially since not everyone will have updated Date::Manip since March 2015 when the
           warning was added.

       Bug fixes
           Changed requirement for ExtUtils::MakeMaker to 6.67_01.  RT 112286

           Fixed a bug where a timezone abbreviation was not parsed correctly when passed in as a value  to  the
           SetDate, ForceDate, or TZ config variables.  Based on a report in perlmonks.org.

       Time zone fixes
           Newest zoneinfo data (tzdata 2016d)

           Made  some  improvements  to  how  I handled the timezone data which resulted in a few of the default
           timezones being changed.

       Documentation fixes
           Fixed one more typo.  RT 114095

           Clarified the Config document.  Based on a report in perlmonks.org.

VERSION 6.53 (2016-03-02)

       Bug fixes
           Date::Manip::Delta::cmp had a bug in it's comparison.  Ian Gibbs.

           The secs_since_1970_GMT method was missing a test to see if it was a valid object.  RT 111915

       Time zone fixes
           Newest zoneinfo data (tzdata 2016a)

       Documentation fixes
           Lots of typos fixed.  I was using podspell to do spell checking, but it was discarding too much  real
           text  (which  wasn't getting checked as a result).  Switched to pod2text which does a better job.  RT
           110025

VERSION 6.52 (2015-12-01)

       Added date ranges on unmodified dates in Recur
           The date range can now be specified for either the fully modified dates,  or  the  unmodified  dates.
           This   will   make   it   easier   to   work   with   holidays   in   some   instances.    Based   on
           <http://perlmonks.org/?node_id=1148735>.

       Added IWn and NWn recurrence modifiers
           Based on <http://perlmonks.org/?node_id=1148735>.

       (!) Reworked holidays slightly
           Previously, every line in the Holidays section defined a unique holiday.  Now,  the  names  determine
           the list of holidays.

           It  is  not  allowed  to  have  two  separate holidays named exactly the same.  It IS allowed to have
           complex holidays that require two (or more) lines in the Holidays section to define them completely.

           Based on <http://perlmonks.org/?node_id=1148735>.

       Bug fixes
           Fixed a bug where the RecurRange config variable wasn't getting used.

           Fixed a bug where some deltas were not parsed correctly as dates.  RT 109600

       Time zone fixes
           Newest zoneinfo data (tzdata 2015g)

       Test fixes
           Added a number of new tests based on Devel::Cover.

VERSION 6.51 (2015-09-01)

       Changes suggested by perlcritic
           Played with perlcritic and made a few minor changes based on it's suggestions.  I doubt  I  will  use
           perlcritic significantly.

       (!) Date::Manip::Delta::value now returns an empty string
           If a delta has an error, or no valid delta in it, the value method returns an empty string instead of
           undef.   This  is  to  be  consistent with the Date::Manip::Date::value method which returns an empty
           string.

       Bug fixes
           Fixed a bug where date/delta calculations with deltas that are too large was not  working  correctly.
           They now set an error condition and fail.  RT 105737

           Fixed a bug introduced by the previous patch and luckily discovered pre-release by Tom Wyant.

           Fixed code that produced a warning in 5.22.0.  Tom Wyant

       Improved DM6 ParseDate and ParseDateString
           Added @opts argument.  Based on RT 105622.

       Time zone fixes
           Newest zoneinfo data (tzdata 2015f)

           Now  uses  /etc/localtime  as  a method to determine the local timezone.  Patch supplied in RT 105159
           (modified by me).  The patch uses some code derived from DateTime::TimeZone .

           Clearer message when the date is not valid in the timezone.

       Test fixes
           Added a number of new tests based on Devel::Cover.  Over the  next  several  releases,  I  intend  to
           continue to add tests until coverage is 100%.

       Documentation fixes
           Fixed a typo.  RT 105546

VERSION 6.50 (2015-06-01)

       Bug fixes
           Not  really  a  bug,  but  6.49  got  a  bunch of NYTprof data bundled with it by mistake.  It's been
           removed.  RT 103252

           Fixed a bug where information about whether a date was complete  or  truncated  was  discarded.   Jim
           Avera

           Fixed a bug where SetDate with a zone alias failed.

           Added  the  Format_MMMYYYY config variable to allow the truncated format mmmYYYY to be parsed instead
           of mmmDDYY.  David W. Morganwalp and RT 103142

           Fixed Makefile.PL/Build.PL to correct for a change on perl on windows which changes a  module  prereq
           requirement.  Alexandr Ciornii

       Time zone fixes
           Newest zoneinfo data (tzdata 2015d)

           Added aliases for older HP-UX time zones.  RT 104141

           Fixed URL for tzdata.  Mohammad S Anwar (GitHub #3).

           Better POD formats.

           Fixed a documentation error.  RT 103966

VERSION 6.49 (2015-03-01)

       Added a deprecation warning
           The TZ config variable is going away.  Added a deprecation warning.

       Some speedups for timezone handling
           Based on RT 102284, I have done some optimization of the timezone handling code.

       Bug fixes
           Added the missing is_date base method to Date::Manip::Base.  Mario Domgoergen.

       Time zone fixes

       parse_time now parses ISO 8601 times
           The parse_time routine wouldn't correctly parse ISO 8601 times.  This is now fixed.

       Parsing special dates with timezones now works
           Parsing special date formats with timezones is now supported such as:

              Christmas at noon PST
              in 3 days at noon PST
              now PST
              epoch 3000000 PST

       dm_zdump modified
           To match the newest version of zdump, the gmtoff is now added at the end of each line.

       Bug fixes
           Fixed  a  bug in the printf method that would not handle embedded newlines correctly (and resulted in
           an infinite loop if it were preceded by a '%').  Henrique Martins

           Fixed a bug where '24:00' was not parsed correctly (though '24:00:00' was).

VERSION 6.38 (2013-01-08)

       (*) Tar file format corrected
           Problems  were  reported on several OSes by people unable to install Date::Manip (and other modules).
           It turns out that the version of tar distributed by my  linux  distro  (OpenSuSE)  uses  the  'posix'
           format instead of the traditional 'gnu' format by default.  This causes problems for some versions of
           tar.   I  have  had  reports  from  OSX,  Windows, and SunOS.  Future versions of Date::Manip will be
           explicitly distributed in the 'gnu' tar archive format.

           Reported by Jay Allen and RT 80594.

       (*) Date::Manip 5.xx end-of-life
           Date::Manip 5.xx is now officially out of support.  I will not be doing any further work on it.   The
           only exception is that I will consider adding user supplied patches on a case-by-case basis.

           If at all possible, please use Date::Manip 6.xx instead.

       (!) Removed some deprecated config variables
           The following config variables have been removed.

              IntCharSet
              RecurNumFudgeDays

VERSION 6.36 (2012-10-31)

       This was an interim release to fix the version numbers (6.35 was released with all of the version numbers
       6.34).

VERSION 6.35 (2012-10-31)

       This was an interim release to fix the problem with the PATH being replaced.

       Removed dependency on YAML
           I've reverted the language data files to perl literals instead of YAML.  Though not quite as easy  to
           maintain, it solves a few problems.  Patch provided by Christopher Madsen.

       Bug fixes
           Last  versions  fix for RT 78566 overrode the PATH even when that wasn't appropriate.  This is fixed.
           Report and patch supplied by RT 80435.

VERSION 6.34 (2012-09-04)

       This is a bug fix so that the PATH won't break non-unix installs.

       Bug fixes
           Put the PATH inside the Unix section so it doesn't affect non-unix environments.  Geoff Rowell

VERSION 6.33 (2012-09-01)

       Improvements to Date::Manip::Delta
            Added convert method.  This had been planned since 6.30, but based on  a  discussion  with  Henrique
            Martins, I moved it up in priority.

            Cleaned up handling of delta field lengths (they are now only calculated once.

            Added cmp method.  Henrique Martins

       Bug fixes
            The  language  modules read from the DATA section, but I never closed the filehandle.  This is fixed
            now.  Patch by Doru Theodor Petrescu

            Added better loading of DM5/DM6 modules.  RT 78512

            Added a secure PATH to TZ.pm for taint reasons.  In response to RT 78566

       Time zone fixes

            desktop.  RT 78566

            Newest zoneinfo data (tzdata 2012e)

       Documentation fixes
            Minor fix.  Henrique Martins

VERSION 6.32 (2012-06-01)

       Modified Build.PL
           Build.PL  now  has better support for building (or not building) HTML files.  Apparently this is slow
           on Windows.  Patch provide in RT 75118.

       Bug fixes
           Fixed a bug in business day calculations.  RT 76336

           Fixed a bug where Delta/Recur objects weren't correctly created.  Zsban Ambrus

           Fixed a bug where SetDate/ForceDate config variables could not be included in a file.  Jerry Wilcox

       Time zone fixes
           Newest zoneinfo data (tzdata 2012c).

       Documentation fixes
           Better support for UTF-8 in autogenerated language module pod files.

VERSION 6.31 (2012-03-01)

       Added extended formats to printf method.
           These include the %<A=NUM>, %<a=NUM>, %<v=NUM>, %<B=NUM>, %<b=NUM>, %<p=NUM>, and  %<E=NUM>  formats.
           Chris Jackson

       Can now parse formats where the time and zone are not adjacent
           A  string  like  'Jan  21  17:13:27  2010  -0400'  can  now  be parsed.  Requested on perlmonks ('Can
           Date::Manip parse a unix timestamp' thread).

       Added PeriodTimeSep config variable.
           This allows you to use a period as a time separator.  Ed Avis

       Holidays can be used as date strings
           You  can  now  parse  a  holiday  name  in  the  Date::Manip::Date::parse   method.    For   example,
           parse('Christmas').  Requested by Abigail.

       Added new recur modifiers
           Added WDn, IBD, and NBD modifiers.

       Added a new date format
           You can now parse '2nd day in May' formats. Randy Harmon

       More flexibility in parsing timezones with both offset and abbrev
           If  you  include  both the offset and abbreviation in the timezone portion of a date, the parenthesis
           around the abbreviation are now optional, so you can parse both:

              -04:00 (EDT)

       Deltas now support fractional values.
           You can now use a delta of 1.5 days.  RT 42699

       Multiple holidays supported
           A date may now have multiple holidays.  Keith Minkler

       Bug fixes
           Fixed a bug where abbreviations were not being examined case insensitively.  Jurgen Muck

           The Holidays section may be safely split across multiple config files.  A  bug  prevented  this  from
           working before.

       Language fixes
           The Norwegian translation was broken due to a typo in the language module.

           Included complete documentation for each language.

           Fixed a couple problems with Danish.  Nicholas Oxhaj

           Added Finnish (from a VERY old mail that I overlooked somehow).  Iikka Virkkunen

           Cleaned up the values used by printf directives to give the expected result.

       Documentation fixes
           Fixed a typo.  Nicholas Bamber

VERSION 6.30 (2012-01-11)

       (*) (!) Reworked deltas
           Much of the delta code was reworked.

           The  constraint  that  a  day is treated as 24 hours was removed (by adding the concept of semi-exact
           deltas) to better handle daylight saving time calculations.

           Made cosmetic changes to which signs will be included in a delta to make the  deltas  more  readable.
           Signs which are the same as the next higher field will be omitted, even if they cross set boundaries.

           Added support for non-normalized deltas.  See the $no_normalize option for the parse and set methods.

           Removed limitations on subtract=2 not working with business calculations.

           Thanks  to discussion on perlmonks, and RT 65774 that prompted me to do this.  I'd been wanting to do
           it for some time, but the discussion on perlmonks made me realize that this needed to be much  higher
           priority.

       (!) Modified Delta_Format
           In conjunction with the above work, added the 'semi' mode to Delta_Format.

       (!) Removed some deprecated config variables
           The following config variables have been removed.

              GlobalCnf
              IgnoreGlobalCnf
              PersonalCnf
              PersonalCnfPath
              PathSep

              Internal
              DeltaSigns
              UpdateCurrTZ
              ConvTZ
              OldConfigFiles
              ResetWorkDay

       Time zone fixes
           Newest zoneinfo data (tzdata 2011n).  RT 71595

           Corrects a bug where +0000 and -0000 offsets were not parsed correctly.  Aaron Hall

           The zoneinfo data includes rules more than 20 years in the future, so we now store 30 years of future
           dates instead of 20 to catch these rules.

           When parsing the timezone portion of the date, timezone abbreviations now take higher precedence than
           zone  names (since that is how timezone information is typically specified).  That only impacts dates
           where the a timezone name is the same as an abbreviation, such as 'CET'.

           Previously, a date with CET in it was interpreted as in the CET timezone.  Now it is  interpreted  as
           in a timezone with the CET abbreviation.

       Better handling of undef in DM6
           The  date/delta  parsing routines in DM6 will now handle an undef argument without issuing a warning.
           Earl C. Ruby III

       Bug fixes
           Fixed a bug with the parse_format %f and %i formats.  Tommi Rintala

           Fixed a bug where the Date::Manip::Delta::set function didn't work to set the month value.

           Fixed a bug where parsing some dates near during a DST change failed.

           Minor bug fix when using Delta_Format.  Prompted while investigating RT 41095.

VERSION 6.25 (2011-08-31)

       Relaxed one constraint in ISO 8601 dates
           A time separated by whitespace from the date can use a single digit hour.  Yuming Philip Xiang

       (*) Set official removal dates for old config variables
           Config variables will be removed 2 years after they are deprecated (except for the TZ variable which,
           due to it's wide use, will be kept for 4 years).

       Time zone fixes
           Newest zoneinfo data (tzdata 2011i)

VERSION 6.24 (2011-06-13)

       New features
           Spaces are ignored in the SetDate/ForceDate config values.  Zsban Ambrus

       Bug fixes
           Fixed a bug where 'in one week' wasn't correctly parsed.  E. M. Shtern

           Fixed a bug where options passed in to the 'new' as a listref weren't handled properly.  Zsban Ambrus

       Time zone fixes
           Newest zoneinfo data (tzdata 2011g)

VERSION 6.23 (2011-04-15)

       (!) Renamed one Date::Manip::Recur method
           The Date::Manip::Recur::base method has been renamed  to  basedate  .   The  Date::Manip::Recur::base
           method should return the Date::Manip::Base object like all the other Date::Manip modules.

       (*) Reworked holidays defined as recurrences
           Improved  dealing  with  the  bootstrap  problem  of defining holidays, especially those that contain
           business day flags.  Mike Tonks

       New features
           The printf function will now take multiple format strings and return a list of values.  Zsban Ambrus

       Bug fixes
           Fixed a bug where GlobalCnf wasn't working.  Peter Edwards

           Improved error messages in a few cases.

           Fixed a bug where one invalid date/timezone check was ignored.  Morten Bjornsvik

           Fixed a bug where '$base2 = new Date::Manip::Base $base1' wasn't working.  RT 67143

           Fixed a bug where passing dates in to the Recur->dates method failed.  RT 67144

           Fixed a bug where the mode wasn't being preserved correctly for a delta.  RT 67150

           Fixed a bug in recurrences where a base date outside of a date range with a very uncommon  recurrence
           format would not work correctly.

           Fixed a problem where the '%s' printf option didn't work in GMT.  Jean-Michel Hiver

       Time zone fixes
           Newest zoneinfo data (tzdata 2011f)

       Documentation fixes
           Fixed two bad recurrence examples in the documentation.  Peter Edwards and Mike Tonks

VERSION 6.22 (2011-03-07)

       Time zone fixes
           Newest zoneinfo data (tzdata 2011b)

           Fixed a bug where the gmtoff method of getting the local timezone was broken.  Martin Zinser.

           Fixed  the  'env'  method  of  determining  the local time zone to allow the value to be an offset of
           seconds since UTC.  This allows the VMS SYS$TIMEZONE_DIFFERENTIAL variable to work correctly.  Martin
           Zinser.

           Removed the SYS$TIMEZONE_RULE method from VMS since the value stored there  is  not  the  name  of  a
           timezone (it's a rule in a non-standard format).  Based on discussion with Martin Zinser.

           Improved  the  order  in  which aliases, abbreviations, etc., are tested to test current usage before
           non-current usage (there were a few cases where old usages were getting tested before current usage.

       Language fixes
           The module will now die if a language module cannot be  loaded  (most  likely  due  to  a  YAML::Syck
           issue).  Based on discussion with Martin Zinser.

       Documentation fixes
           Added a sample config file document.  Based on discussion with Rich Duzenbury.

VERSION 6.21 (2011-01-10)

       New features
           Deltas  may  now  contain  spelled  out  numbers,  so 'in 2 weeks' and 'in two weeks' will both work.
           Daniel Shahaf

       Bug fixes
           Fixed a bug where week_of_year didn't work in some cases.  Chris Eveland.

           Fixed a minor potential bug.  Geraint Edwards.

       Time zone fixes
           Updated windows time zone aliases.  Daniel Harding

       Language fixes
           Added Norwegian.  Glenn Sogn

VERSION 6.20 (2010-12-01)

       (*) (!) Reworked recurrences
           Recurrences were reworked in a (slightly) backward incompatible way to improve their usefulness  (and
           to make them conform to the expected results). Most recurrences will work the same as previously, but
           a few will differ. Most of this was suggested by Jay Jacobs.

           A  recurring event is now calculated relative to the base date, NOT relative to a previous event. For
           example, if a recurrence occurs every month, and the base date was Jan 31, then previously, recurring
           events would have been (in a non-leap year):

              D(0)                   = Jan 31
              D(1)  = D(0) + 1 month = Feb 28
              D(2)  = D(1) + 1 month = Mar 28
              ...

           The new behavior is:

              D(0)                       = Jan 31
              D(1)  = D(0) + 1*(1 month) = Feb 28
              D(2)  = D(0) + 2*(1 month) = Mar 31
              ...

           Previously, if a base date were not specified, it was not determined from the date  range.  Now,  the
           start date of the date range acts as the base date.

           The meaning of the base date has changed slightly. It is much more meaningful and useful now.

           Added iterator functions.  Daniel LaLiberte

           The RecurNumFudgeDays variable is no longer used and is deprecated.

       Time zone fixes

VERSION 6.14 (2010-10-20)

       (*) Date::Manip 5.xx fully integrated with 6.xx
           Date::Manip 5.xx and 6.xx are both installed automatically, and the correct one will be chosen.

       Bug fixes
           Fixed a bug where recurrence handling was broken.  RT 62128

       Documentation fixes
           A lot of documentation was cleaned up to be easier to read, and better organized.

VERSION 6.13 (2010-10-13)

       New features
           Added the input methods to Date::Manip::Date and Date::Manip::Delta.  Ed Avis.

           The 'date +%z' command will also be used to determine the timezone.  Oliver Schulze

       Bug fixes
           Several  changes  to try to get rid of a memory leaks reported in RT 54937.  Huge thanks to BrowserUK
           on perlmonks for help.  Unfortunately, it ended up being a bug in perl, and  will  only  be  resolved
           when that bug is fixed. See the Date::Manip::Problems document for more information.

              Reorganized Base/TZ to get rid of circular references.
              Added end blocks to clean some global variables.
              Got rid of switch/given structures.

           Fixed a bug where an incomplete date with 'last' in it was causing an error.  RT 60138

           Fixed a bug where 'Sunday, 9th Jan 1972' wasn't parsed correctly.  RT 57832

       Time zone fixes
           Fixed a bug where Zones.pm was generated with the abbreviations in the wrong order.  Amish Chana.

       Language fixes
           French month abbreviations now support periods.  Bernard Haerri

       Test fixes
           Added tests from RT 29655 to make sure that the problem never recurs.

       Documentation fixes
           Fixed documentation problem with the new_* methods in Date::Manip::Obj.  Options must be passed in as
           \@opts rather than @opts.

           Cleaned up some of the documentation.

VERSION 6.12 (2010-09-27)

       (!) 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.

           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 (correcting 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 Jerry Wilcox.

       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.

           Working with fractional days  was  suggested  by  Peter  van  Hardenberg.   This  is  implemented  in
           Date::Manip::Base::day_of_year method.
