NAME

       Date::Manip::Changes5 - changes in Date::Manip 5.xx

SYNOPSIS

       This describes the changes made to the Date::Manip module in the 5.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 5.xx

       As of December 2012, Version 5 of Date::Manip will no longer be modified.  It is expected
       that version 5.64 will be the final release.

       The one exception is that if someone submits a patch that applies cleanly and causes zero
       failures in the test suite, I will consider adding it on a case-by-cast bases.

       Please use Date::Manip 6.xx instead.

VERSION 5.64 (Released with 6.32)

       Better handling of '0000' timezone
           Applied a patch supplied by Ed Avis that improves handling of the '0000' timezone..

VERSION 5.63 (Released with 6.26)

       Fixed business mode calculation
           Applied a patch that I received some time ago to fix a business mode calculation.
           Steve Tempest

VERSION 5.62 (Released with 6.21)

       No changes

VERSION 5.61 (Released with 6.20)

       No changes

VERSION 5.60 (Released with 6.14)

       Fully integrated with 6.xx
           As of Date::Manip 6.14, the 5.xx release is fully integrated into the distribution.
           Both will be installed automatically and you can switch between them (if you have a
           recent version of perl). This simplifies the package management process considerably.
           The downside is that Date::Manip 6.xx will be installed, even if you do not have a
           recent version of perl and cannot use it.

VERSION 5.59 (Released with 6.12)

       Test fixes
           Fix tests to work better on windows.

VERSION 5.58 (Released with 6.11)

       Test fixes
           Fixed a bug in some of the tests that were causing two tests to fail.  JD

           Explicitly set TZ in all tests to avoid some failures (it got left out of a few when
           it was bundled with 6.10).

VERSION 5.57 (Released with 6.10)

       (*) Combined 5.xx and 6.xx
           As of 6.10, Date-Manip-6.xx will contain both the Date::Manip 5.xx and 6.xx modules.
           If perl 5.10 or higher is available, the 6.xx version will be installed. For older
           versions of perl, the 5.xx version will be installed.

           This will allow all of the automatic module tools to work correctly.

       Bug fixes

       (*) Added time zone abbreviations
           Date::Manip 5.xx now includes all of the time zone abbreviations from version 6.xx

VERSION 5.44 (2005-06-02)

       Released

VERSION 5.43 (DEVELOPMENT)

       (!) (*) Recurrences revisited
           The behavior of some elements of recurrences changed. These included making the week
           element (N) refer to the Nth occurrence of a day of the week in the week, month, or
           year. It is now possible to look at the 3rd Friday of every month for example.

           Y-0-WOY-DOW now refers to the WOY'th occurence of DOW instead of the ISO 8601 date
           Y-W(WOY)-DOY. Also, changed Y-0-WOY-0 to refer to the WOY'th occurence of FirstDay,
           and got rid of the MW and MD flags. Many other similar changes.

       (!) Changed %x format in UnixDate
           The %x format used to be equivalent to %D (%m/%d/%y), but it has been modified to use
           the DateFormat config variable, so it may return %d/%m/%y if a non-US DateFormat is
           specified.

       New features
           Added TodayIsMidnight.  Reuben Thomas

           Added "approx" mode to Delta_Format and reversed change to default Delta_Format

           Fix for a potential problem in the "0000" time zone.  Ed Avis

           Modified %x UnixDate format to use DateFormat config variable.  Matt Lyons

       Time zone fixes

           ISO 8601 T and W dates.  Hugo Cornelis

           Small correction to Brazil time zones.  John McDonald

           Added time zones.  Michael Wood-Vasey, Don Robertson, Michael D. Setzer II, Andres
           Tarallo

           release.

VERSION 5.41 (DEVELOPMENT)

       As of 5.41, odd numbered releases are development (and appear only on my page). Even
       number releases are official releases submitted to CPAN.

       (!) Changed path separator for VMS
           Since ":" is used in some VMS paths, it should not have been used as the path
           separator.  It has been changed to a newline ("\n") character.

       (!) Delta_Format behavior changed
           The entire delta is exact if no month component is present (previously, no year or
           month component could be present).  Due to discussion with Tim Turner.

           Fixed a bug where spaces in a date caused problems in German (due to the number 1st,
           2nd, etc. being 1., 2., etc.).  Erik Roderwald

           Added Danish.  Jesper Dalberg
              A patch for Danish was send by Jorgen Norgaard previously, and
              I somehow overlooked it. I apologize for that.

       Test fixes
           Added runtests.bat contributed by Lon Amick

           The Date_DaysSince999 function (deprecated in 5.35) has been removed.

       New features
           Added support for ISO8601 dates of the format dateTtime.  Jason Pierce

           Got rid of the "use Cwd" and ENV{PATH} lines which means no more taint problems.

       Bug fixes

VERSION 5.35 (1999-07-06)

       (!) Deprecated Date_DaysSince999
           In fixing support for the years 0001-0999, I rewrote Date_DaysSince999 to be
           Date_DaysSince1BC.  The Date_DaysSince999 function will be removed.

       (*) (!) Added PathSep variable
           In order to better support Win32 platforms, I added the PathSep config variable.  This
           will allow the use of paths such as "c:\date" on Win32 platforms.  Old config files on
           Win32 platforms (which were not working correctly in many cases) may not work if they
           contain path information to the personal config file.

       (*) Recurrences now support flags
           Flags for modifying recurrence dates are now supported.

       (*) Improved holiday support considerably
           Added support for recurrences and one-year-only holidays (the latter requested first
           by Vishal Bhatia.

       (*) Date_Init improved
           Date_Init can now return a list of config variables if called in array context.  Based
           on a suggestion by Matt Tuttle.

       New features
           Modified Date_GetPrev/Date_GetNext to take $curr=2.

           Now parses the Apache log file format "dd/mmm/yyyy:hh:mm:ss (time zone)".  Mark
           Ferguson

           Added OS/2 support.  Michael B. Babakov

           Added Date_IsHoliday routine.  Joe Pepin

           Added recurrence support for Easter (first suggested by Abigail).

       Bug fixes
           Made "epoch" not case sensitive and fixed a bug where it would fail in some languages.
           Caught because of Iosif's thorough Romanian test file.

           Fixed a problem where "in 5 days/weeks/months" sometimes wouldn't get correctly parsed
           in other languages.  Caught because of Iosif's thorough Romanian test file.

           Fixed a weakness in ParseDateDelta brought out by the Romanian delta test file.

           Fixed a bug causing warnings in the beta version of perl.  Patch by Paul Johnson.

           Several recurrence bug fixes.

           Put all the my'ed global variables in a couple hashes to clean up the namespace and to
           make a few future enhancements easier to do.

           Fixed a bug where business weeks weren't being used correctly.  Qian Miao

           Fixed a serious typo in the DaysSince1BC routine.  Qian Miao

           Fixed Veteran's day, added Good Friday (off by default).  Peter Chen

           Cleaned up holiday variables and re-did holiday routines.

           Corrected Swedish translations.  Danne Solli

           Some fixes to German translations.  Peter Ehrenberg

           Added Italian.  Nicola Pedrozzi

       Test fixes
           Added recurrence test suite

       Documentation fixes
           Several documentation updates.

           New recurrence documentation.

VERSION 5.34 (1999-04-13)

       (!) (*) All Date::Manip variables are no longer accessible
           Previously, Date::Manip variables were declared using a full package name.  Now, they
           are declared with the my() function.  This means that internal variables are no longer
           accessible outside of the module.  Based on suggestion by Tom Christiansen

       (!) Week interpretation in business mode deltas
           A business mode delta containing a week value used to be treated as 7 days.  A much
           more likely interpretation of a week is Monday to Monday, regardless of holidays, so
           this is now the behavior.

       (!) %z UnixDate format
           The %z UnixDate format used to return the time zone abbreviation.  It now returns it
           as a GMT offset (i.e. -0500).  %Z still returns the time zone abbreviation.  Suggested
           by Tuc.

       (!) Formats "22nd Sunday" returns the intuitive value
           The date "22nd Sunday" used to return the Sunday of the 22nd week of the year (which
           could be the 21st, 22nd, or 23rd Sunday of the year depending on how weeks were
           defined).  Now, it returns the 22nd Sunday of the year regardless.

       (!) Separator in DD/YYmmm and mmmDD/YY formats no longer optional
           Previously, the date "Dec1065" would return Dec 10, 1965.  After adding the YYYYmmm
           and mmmYYYY formats, this was no longer possible.  The separator between DD and YY is
           no longer optional, so

              Dec1065     returns December 1, 1065
              Dec10/65    returns December 10, 1965

       (*) Date_Cmp added
           In one of the next versions of Date::Manip, the internal format of the date will
           change to include time zone information.  All date comparisons should be made using
           Date_Cmp (which currently does nothing more than call the Perl "cmp" command, but
           which will important when comparing dates that include the time zone).

           Added now in response to a question by Al Sorrell (I should have added it earlier).

       New features
           Added exact business mode.  Ian Duplisse

           Added "mmmYYYY" and "YYYYmmm" formats.  As a result, "DDYYmmm" and "mmmDDYY" formats
           changed to "DD/YYmmm" and "mmmDD/YY" as described above.  David Twomey

       Bug fixes
           Fixed a bug where a date passed in as an array wasn't getting the date removed from
           the array.  Rick Wise

           Added tests for MPE/iX OS.  John Testa

           Fixed a bug where WorkDayBeg=8:00 went into an infinite loop.  Mark Martinec

           Changed a business week to be the same as an exact week.  Abigail

           Fixed a bug where "Sunday week 0" didn't work (only affected week 0) Gerald Rinske

           Minor bug (my variable declared twice).  Paul J. Schinder

           Fixed a bug where "epoch SECONDS" was getting parsed wrong (for SECONDS which could be
           interpreted as an ISO-8601 date).  N. Thomas

           Fixed a problem where init files were not being read.  Mike Reetz

       Time zone fixes
           At the request of the UN, I added the SAT time zone.  :-) Howard Hendler

           Fixed a bug where time zones were converted multiple times if ConvTZ was set and
           DateCalc called.  Steven Hartland

       Language fixes
           Added Portuguese.  Rui Pedro da Silva Leite Pereira

       Documentation fixes
           A number of typos fixed.  Ron Pero

VERSION 5.33 (1998-08-20)

       Bug fixes
           Fixed a bug where "1 month ago" was no longer working (and added it to the test
           cases).  This broke when I fixed the "-1second" bug in the previous version.  A result
           of this is that a number of "deltas" can be parsed as dates (i.e. &ParseDate("1 hour
           20 minutes ago") is equivalent to &DateCalc("now","1 hour 20 minutes ago")).  Only
           text deltas can be used in this way (i.e. &ParseDate("-0:0:0:0:1:20:0") will not
           work).

       Language fixes
           Added Spanish support.  Bautista Jasso Javier

VERSION 5.32 (1998-08-17)

       (!) Date_Init arguments
           The old style Date_Init arguments that were deprecated in version 5.07 have been
           removed.

       (!) (*) DateManip.cnf change
           Changed .DateManip.cnf to Manip.cnf (to get rid of problems on OS's that insist on 8.3
           filenames) for all non-Unix platforms (Windows, VMS, Mac).  For all Unix platforms,
           it's still .DateManip.cnf .  It will only look in the user's home directory on VMS and
           Unix.

       New features
           Added "in N days" and "N days ago" formats.  Tony Bowden.

           Added cYYYY format to YYtoYYYY variable.  Mark Rejhon.

           Added 2 days/weeks/months later in both ParseDate and ParseDelta (for Dutch support).
           Abigail.

           Added "Y:M:0*-DOM:0:0:0" to ParseRecur.  Jeff Yoak.

           Fixed a bug where the deltas could be off by up to a couple minutes in some rare
           cases.  Herman Horsten.

           Fixed an "uninitialized symbol" warning.  Mark D. Anderson.

           Fixed a bug where holidays weren't erased.  Jonathan Wright.

           Applied a bug fix from Joe Chapman where the %W/%U UnixDate formats were frequently
           wrong.

           Several minor fixes and improvements.  Abigail.

           Added some VMS support.  Charles Lane.

           Fixed a bug which caused a test to fail on some systems.  Charles Lane.

           Fixed a bug where "-1second" was treated as a date rather than a delta in DateCalc.
           Kenneth Ingham

           Added a bit to the Makefile.PL (as it was distributed in the Win32 Perl Resource Kit).
           Murray Nesbitt

       Time zone fixes
           Allowed time zones of the format STD-#DST-#.  Peter Gordon.

           Added time zone support for "+0500 (EST)".  Tom Christiansen.

           Restricted time zones parsing to 0000-2359 instead of 0000-9999.  Frank Cusack

           Added time zones.  W. Phillip Moore, Michael Smith, Samuli Karkkainen

       Language fixes
           Added Polish support.  Ian Wojtowicz.

           Added Dutch support.  Abigail.

           Added A.M. and P.M. parsing (not just AM and PM).  William W. Arnold.

           Fixed a German initialization problem.  Thomas Horster-Moller and Christian Reithmaier

       Documentation fixes
           Documentation fix.  Peter Gordon.

           Minor documentation changes.  Yamamoto Hiroshi.

           Added info about the RCS problem.  Supplied by Kipp E. Howard.

VERSION 5.31 (1998-04-08)

       New features
           Added "epoch SECS" format to ParseDateString.  Thanks to: Joshua M. Burgin.

           Added a patch by Blair Zajac to make Date_NthDayOfYear work with decimal days.

       Bug fixes
           Fixed a bug in ParseDateDelta (seems to appear only in 5.005 pre-releases).  Found by
           Larry W. Virden.

           Missed one form in ParseDate.  Noted by Tuc.

           Fixed a bug where "15:00:00" couldn't be parsed.  Michael Pizolato.

           Split Manip.pm.  New files are HISTORY, TODO, Manip.pod.

           Fixed a bug in ParseDateDelta.  Antonio Rosella.

           Removed the only occurence of $& (which may speed some things up).  Fix by Ken
           Williams.  First suggested by Abigail.

           Fixed an overflow bug in doing date calculations with 2 dates more than 70 years
           apart.  Fix by Vishal Bhatia.

           Fixed a bug where "5:00pm" wasn't always parsed correctly.  Thanks to Jim Trocki.

           Fixed a bug in UnixDate (it wouldn't return the correct string for a format who's last
           character was '0') noted by Ramin V.

       Time zone fixes
           Relaxed some restrictions on time zones so ISO-8601 dates can use non-ISO-8601 time
           zones.  Noted by John Chambers.

           Fixed a bug in converting time zones with a minutes field (+1030).  Found by Paul O.

       Language fixes
           Some fixes to the French translations by Emmanuel Bataille.

           Added German support.  Thanks to Andreas C. Poszvek.

       Documentation fixes
           Minor documentation fixes.  Will Linden.

           Fixed a documentation problem with Date_GetPrev.  It was still 0-6 instead of 1-7.
           Thanks to Robert Klep.

VERSION 5.30 (1998-01-21)

       (!) (*) Delta format changed
           A week field has been added to the internal format of the delta.  It now reads
           "Y:M:W:D:H:MN:S" instead of "Y:M:D:H:MN:S".

       (*) Now handles recurring events
           Added ParseRecur.  First suggested by Chris Jackson.

       New features
           All routines can now take either a 2- or 4-digit year.

           Added Delta_Format.  First suggested by Alan Burlison.

           Added Date_SetDateField.  Thanks to Martin Thurn.

       Bug fixes
           Made the $err argument to DateCalc optional.

           Changed the name of several of the library routines (not the callable ones) to
           standardize naming.

VERSION 5.21 (1998-01-15)

       (!) Long running processes may give incorrect time zone
           A process that runs during a time zone change (Daylight Saving Time specifically) may
           report the wrong time zone.  See the UpdateCurrTZ variable for more information.

       (!) UnixDate "%J", "%W", and "%U" formats fixed
           The %J, %W, and %U will no longer report a week 0 or a week 53 if it should really be
           week 1 of the following year.  They now report the correct week number according to
           ISO 8601.

       New features
           Added YYtoYYYY variable.  Suggested by Michel van der List.

           Added the UpdateCurrTZ variable to increase speed at the cost of being wrong on the
           time zone.

           Added British date formats.  Thanks to Piran Montford.
              Monday week
              today week
              as well as some US formats
              in 2 months
              next month

           Time can now be written 5pm.  Piran Montford.

           Added the TomorrowFirst variable and Date_NearestWorkDay function.

           Added UnixDate formats %G and %L to correctly handle the year.  Thanks to Samuli
           Karkkainen.

           Added ForceDate variable. Based on a suggestion by Christian Campbell.

       Bug fixes
           Now passes Taint checks.  Thanks to Mike Fuhr, Ron E. Nelson, and Jason L Tibbitts
           III.

           Put everything in a "use integer" pragma.

           Added a missing space in the %g UnixDate format.  Thanks to Mike Booth.

           Removed all mandatory call to Date_Init (only called when current time is required).
           Significantly faster.

           Fixed a bug in Date_ConvTZ.  Thanks to Patrick K Malone.

           Fixed a bug in Date_IsWorkDay.

       Time zone fixes
           Fixed some Australian time zones.  Kim Davies.

       Language fixes
           Cleaned up multi-lingual initialization and added the IntCharSet variable.

           Improved French translations.  Thanks to Emmanuel Bataille.

           Added "Sept" as a recognized abbreviation.  Thanks to Martin Thurn.

           Typo in the French initialization.  Thanks to Michel Minsoul.

       Test fixes
           Fixed the tests to not fail in 1998.

       Documentation fixes
           Documented how to get around Micro$oft problem.  Based on a mail by Patrick Stepp.

VERSION 5.20 (1997-10-12)

       (*) ISO 8601 support
           ISO 8601 dates are now parsed. This resulted in several other changes specified below.

       (!) (*) ParseDate formats removed
           As a result of ISO 8601 support, some formats which previously worked may no longer be
           parsed since they conflict with an ISO 8601 format.  These include MM-DD-YY (conflicts
           with YY-MM-DD) and YYMMDD (conflicts with YYYYMM).  MM/DD/YY still works, so the first
           form can be kept easily by changing "-" to "/".  YYMMDD can be changed to YY-MM-DD
           before being parsed.  Whenever parsing dates using dashes as separators, they will be
           treated as ISO 8601 dates.  You can get around this by converting all dashes to
           slashes.

       (!) (*) Week day numbering
           The day numbering was changed from 0-6 (Sun-Sat) to 1-7 (Mon-Sun) to be ISO 8601
           compatible.  Weeks start on Monday (though this can be overridden using the FirstDay
           config variable) and the 1st week of the year contains Jan 4 (though it can be forced
           to contain Jan 1 with the Jan1Week1 config variable).

       New features
           Several new parsing formats added, including:
              "Friday"             suggested by Rob Perelman
              "12th"               suggested by Rob Perelman
              "last day of MONTH"  suggested by Chadd Westhoff

           Added ParseDateString for speed (and simplicity for modifying ParseDate)

           Added %J and %K formats to UnixDate.

           Added Date_DaysInMonth.

       Bug fixes
           Reorganized ParseDate more efficiently.

           Fixed some incorrect uses of $in instead of $future in ParseDate.  Thanks to Erik
           Corry.

           Added some speedups (more to come).

       Test fixes
           Cleaned up testing mechanism a bit and added tests for ISO 8601 formats.

VERSION 5.11 (1997-08-07)

       Version 5.11 was never released to CPAN.

       Bug fixes
           Added one more check for NT perl.  Thanks to Rodney Haywood.

           Added some comments to help me keep my personal libraries up-to-date with respect to
           Date::Manip and vice-versa.

           Fixed a bug which showed up in French dates (though it could happen in other languages
           as well).  Thanks to Georges Martin.

           Fixed a bug in DateCalc.  Thanks to Thomas Winzig.

           Removed the "eval" statement from CheckFilePath which causes a suid c wrapper program
           to die when it calls a Date::Manip script.  Thanks to Hank Hughes.

           Fixed a bug in business mode calculations.  Thanks to Sterling Swartwout.

           Fixed a bug in which "1997023100:00:00" was accepted as valid.  Thanks to Doug
           Emerald.

           Fixed a bug in which ConvTZ was not used correctly in ParseDate.  Re-did portions of
           Date_ConvTZ.  Thanks to Vivek Khera.

           Fixed a bug in business mode calculations.  Thanks to Ian Duplisse.

           Added $^X check for Win95 perl.  Thanks to Walter Soldierer.

           Missed one call to NormalizeDelta so the output was wrong.  Thanks to Brad A. Buikema.

       Time zone fixes
           Added time zones.  Paul Gillingwater, Rosella Antonio, Kang Taewook

VERSION 5.10 (1997-03-19)

       Bug fixes
           Cleaned up In, At, and On regexps.

           Added 2 checks for MSWin32 (date command and getpw* didn't work).  Thanks to Alan
           Humphrey.

           Fixed two bugs in the DateCalc routines.  Pointed out by Kevin Baker.

           Added a check for Windows_95.  Thanks to Charlie W.

           Cleaned up checks for MacOS and Microsoft OS's.  Hopefully I'm catching everything.
           Thanks to Charlie Wu for one more check.

           Fixed a typo which broke Time%Date (Date=dd%mmm%yy) format.  Thanks to Timothy
           Kimball.

       Time zone fixes
           Fixed some problems with how "US/Eastern" type time zones were used.  Thanks to Marvin
           Solomon.

       Test fixes
           Tests will now run regardless of the time zone you are in.

           Test will always read the DateManip.cnf file in t/ now.

           A failed test will now give slightly more information.

           DateManip.cnf file in t/ now sets ALL options to override any changes made in the
           Manip.pm file.

       Documentation fixes
           Added documentation for backwards incompatibilities to POD.

           Fixed some problems in POD documentation.  Thanks to Marvin Solomon.

           Fixed minor POD error pointed out by John Perkins.

           Changed documentation for Date_IsWorkDay (it was quite confusing using a variable
           named $time).  Thanks to Erik M. Schwartz.

           Fixed typo in documentation (midnight misspelled).  Thanks to Timothy Kimball.

VERSION 5.09 (1997-01-28)

       Bug fixes
           Upgraded to 5.003_23 and fixed one problem associated with it.

           Used carp and changed all die's to confess.

           Replaced some UNIX commands with perl equivalents (date with localtime in the tests,
           pwd with cwd in the path routines).

           Cleaned up all routines working with the path.

       Test fixes
           Tests work again (broke in 5.08).  Thanks to Alex Lewin and Michael Fuhr for running
           debugging tests.

VERSION 5.08 (1997-01-24)

       Bug fixes
           (*) Fixed serious bug in ConvTZ pointed out by David Hall.

           (*) Modified Date_ConvTZ (and documented it).

VERSION 5.07p2 1997-01-03

       Released two patches for 5.07.

       Bug fixes
           Fixed a bug where a delta component of "-0" would mess things up.  Reported by Nigel
           Chapman.

       Time zone fixes
           (*) Can now understand PST8PDT type zones (but only in Date_TimeZone).

           Added lots of time zone abbreviations.

       Test fixes
           Fixed some tests (good for another year).

VERSION 5.07 (1996-12-10)

       (!) UnixDate "%s" format
           Used to return the number of seconds since 1/1/1970 in the current time zone.  It now
           returns the number of seconds since 1/1/1970 GMT.  The "%o" format was added which
           returns what "%s" previously did.

       (!) (*) Internal format of delta
           The format for the deltas returned by ParseDateDelta changed.  Previously, each
           element of a delta had a sign attached to it (+1:+2:+3:+4:+5:+6).  The new format
           removes all unnecessary signs by default (+1:2:3:4:5:6).  Also, because of the way
           deltas are normalized (see documentation on ParseDateDelta), at most two signs are
           included.  For backwards compatibility, the config variable DeltaSigns was added.  If
           set to 1, all deltas include all 6 signs.

       (!) (*) Date_Init arguments
           The format of the Date_Init calling arguments changed.  The old method

              Date_Init($language,$format,$tz,$convtz);

           is still supported , but this support will likely disappear in the future.  Use the
           new calling format instead:

              Date_Init("var=val","var=val",...);

           NOTE:  The old format is no longer supported as of version 5.32 .

       (*) Added weeks to ParseDateDelta.
           Suggested by Mike Bassman.  Note that since this is a late addition, I did not change
           the internal format of a delta.  Instead, it is added to the days field.

       (*) Now reads a config file.
           Refer to the Date_Init documentation for details.

       (*) Added business mode.
           See documentation.  Suggested by Mike Bassman.

       New features
           (*) Modified how deltas are normalized and added the DeltaSigns config variable.

           Added %q format "YYYYMMDDHHMMSS" to UnixDate.  Requested by Rob Perelman.  Also added
           %P format "YYYYMMDDHH:MM:SS".

           Added a new config variable to allow you to work with multiple internal formats (with
           and without colons).  Requested by Rob Perelman.  See Date_Init documentation.

           Added the following formats suggested by Andreas Johansson:
              Sunday week 22 [in 1996] [at 12:00]
              22nd Sunday [in 1996] [at 12:00]
              Sunday 22nd week [in 1996] [at 12:00]

           Added a new config variable to allow you to define the first day of the week.  See
           Date_Init documentation.

           Added the following formats to ParseDate for convenience (some were suggested by Mike
           Bassman):
              next/last Friday [at time]
              next/last week [at time]
              in 2 weeks [at time]
              2 weeks ago [at time]
              Friday in 2 weeks
              in 2 weeks on Friday
              Friday 2 weeks ago
              2 weeks ago Friday

           Added Date_SecsSince1970GMT, moved the %s format to %o (secs since 1/1/70) and added
           %s format (secs since 1/1/70 GMT).  Based on suggestions by Mark Osbourne.  Note this
           introduces a minor backward incompatibility described above.

           Date_SetTime now works with international time separators.

           Added the %g format (%a, %d %b %Y %H:%M:%S %z) for an RFC 1123 date.  Suggested by Are
           Bryne.

           Added options to delete existing holidays and ignore global config file.

           Date_GetNext and Date_GetPrev now return the next/prev occurence of a time as well as
           a day.  Suggested by Are Bryne.

           In approximate mode, deltas now come out completely normalized (only 1 sign).
           Suggested by Rob Perelman.

           Added Date::Manip::InitDone so initialization isn't duplicated.

           Added a 3rd internal format to store YYYY-MM-DD HH:MN:SS (iso 8601).

           Added a config variable to allow you to work with 24 hour business days.  Suggested by
           Mike Bassman.

           ParseDateDelta now returns "" rather than "+0:0:0:0:0:0" when there is an error.

       Bug fixes
           (*) The d:h:mn:s of ALL deltas are normalized.

           Huge number of code changes to clean things up.

           Subroutines now check to see if 4 digit years are entered.  Suggested by Are Bryne.

           Added local($_) to all routines which use $_.  Suggested by Rob Perelman.

           Are Bryne.

           Added WindowsNT check to Date_TimeZone to get around NT's weird date command.  Thanks
           to Are Bryne.

           Fixed typo (CSD instead of CST).

           Fixed sign in military time zones making Date::Manip RFC 1123 compliant (except that
           time zone information is not stored in any format)

       Test fixes
           (*) Added test suite!

VERSION 5.06 (1996-10-25)

           Added %Q format "YYYYMMDD" to UnixDate.  Requested by Rob Perelman.

       Bug fixes
           Fixed another two places where a variable was declared twice using my (thanks to Ric
           Steinberger).

           Fixed a bug where fractional seconds weren't parsed correctly.

           Fixed a bug where "noon" and other special times were not parsed in the "which day of
           month" formats.

           Fixed a minor bug where a few matches were case sensitive.

           The command "date +%Z" doesn't work on SunOS machines (and perhaps others) so 5.05 is
           effectively broken.  5.06 released to fix this.  Reported by Rob Perelman.

VERSION 5.05 (1996-10-11)

       New features
           Changed deltas to be all positive or all negative when produced by DateCalc.

           Now supports times like "noon" and "midnight".

       Bug fixes
           Fixed bug introduced in 5.04 when default day set to 1.  When no date given, have day
           default to today rather than 1.  It only defaults to one if a partial date is given.

           Fixed bug where Date_DaysSince999 returned the wrong value (the error did not affect
           any other functions in Date::Manip due to the way it was called and the nature of the
           error).  Pointed out by Jason Baker

           Dates with commas in them are now read properly.

           Fixed two places where a variable was declared twice using my (thanks to Ric
           Steinberger).

           Hopefully fixed installation problems.

           Got rid of the last (I think) couple of US specific strings.

           Fixed bug in Date_SetTime (didn't work with $hr,$min,$sec < 10).

           Added ModuloAddition routine and simplified DateCalc.

       Time zone fixes
           (*) Now supports time zones.

           (*) Added Date_ConvTZ routine for time zone support.

           Date_TimeZone will now also check `date '+%Z'` suggested by Aharon Schkolnik.

       Language fixes
           Added Swedish translation (thanks to Andreas Johansson

           The time separators are now language specific so the French can write "10h30" and the
           Swedes can write "10.30".  Suggested by Andreas Johansson.

       Documentation fixes
           Fixed bad mistake in documentation (use Date::Manip instead of use DateManip) pointed
           out by tuc@valhalla.stormking.com

                 sensitive)
              full day names not parsed correctly
