Date::Manip::Changes5(User Contributed Perl DocumentatDate::Manip::Changes5(3)

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

       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 (!).

       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

VERSION 5.44 (2005-06-02)

       (!) (*) 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 behavior to the one from version 5.40.	Based on
	   discussion with Adam Spiers.

	   Added %O UnixDate format.  Martin Thurn

       Bug fixes
	   Fixed a bug is ParseRecur where values passed in were no overriding
	   old values in the recurrence.  Scott Barker (reported to the Debian
	   bugs list).

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

	   Changed taint check to be the one in persec(1).  Max Kalika

	   Minor fix so DateInit("VAR=") will work.  Thomas Bohme

	   Fixed a bug where business mode was kept operative even after the
	   calculation was over.  Emiliano Bruni

	   Minor change to run under cygwin.  Niel Markwick

	   Minor VMS fix.  Martin P.J. Zinser

	   Small fix to taint checking.	 David Worenklein

	   be done.  Andras Karacsony

	   Fixed a bug in business mode calculations.  Tracy L Sanders

	   Matt Lyons

       Time zone fixes
	   Fixed a problem with single character military time zones (T and W)
	   conflicting with 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

	   Added the language Catalan.	Xavi Drudis

       Documentation fixes
	   Minor doc fixes  Reuben Thomas, Ed Avis, Thomas Winzig

	   Clarified documentation on %W/%G/%U/%L formats.  Joel Savignon

VERSION 5.42a 2003-07-03
       Test fixes
	   A quick fix to replace a faulty test.

VERSION 5.42 (2003-07-02)
	   Number changed to distinguish between the development release
	   (5.41) and the official release.

       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")

       (!) 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.

       Bug fixes
	   Small patch for OpenVMS.  Martin P.J. Zinser

	   Taint check insecure $ENV{PATH} fix.	 Ed Avis

	   Patch to allow deltas of the form "+ -1 day" to work.  Ed Avis

	   Removed ampersands from function calls in documentation to fit new
	   perl coding standards.  Bill Pollock

	   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

       Time zone fixes
	   Minor bug fix where /etc/time zone not correctly read.  Jacek

	   Made the UnixDate %Z format work with numeric time zones.  Michael

	   Fixed bug where -HH:MM and +HH:MM were not being accepted as valid
	   time zones.	Hank Barta

	   Fixed a bug where time zones -HH:MM weren't handled in ISO 8601
	   dates.  Ed Avis

	   Added some help for VMS time zones.	Don Slutz

	   Added some checking to the time zone determination.	Ed Avis

	   Added time zones.  David Coppit, Daniel Serodio, Fabian Mandelbaum,
	   Raul Dias, Pedro Melo CUNHA, Roman Y Malakhov, David Whiting,
	   Khaled Mostaguir, Jason King

VERSION 5.39 (2000-06-27)
       Bug fixes
	   `date` uses the user's path unless taint checking is on.

	   @::DatePath used instead of @Date::Manip::DatePath incorrectly.
	   Fixed by John Labovitz.

	   Fixed a bug where times such as "5 seconds ago" were not changing
	   over time.  Matthew R. Sheahan

       Time zone fixes
	   Added /etc/time zone support to &Date_TimeZone.  Dirk Eddelbuettel

	   Prompted by Greg Schiedler and paid for by Alan Cezar.

       (!) Removed Date_DaysSince999
	   The Date_DaysSince999 function (deprecated in 5.35) has been

       New features

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

       Bug fixes

	   Fixed a serious bug where HH:24:00 was broken due to support from
	   24:00:00.  Scott Egashira

       Time zone fixes
	   Added time zone.  Paul Arzul

       Documentation fixes
	   Fixed a documentation problem with Date_ConvTZ.  Diab Jerius

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.

	   Fixed support for years 0000-0999.  Requested by Chris Vaughan

	   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

	   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,

	      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

	   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

	   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.

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".

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

	   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

       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

	   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

	   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

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

	   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 file.

       Documentation fixes
	   Added documentation for backwards incompatibilities to POD.

	   Fixed some problems in POD documentation.  Thanks to Marvin

	   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

	   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

       (!) (*) 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


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


	   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

	   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

	   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

	   Complete rewrite of DateCalc.

	   Fixed a bug where UnixDate %E format didn't work with single digit
	   dates.  Patch supplied by Jyrgen Nyrgaard.

	   Fixed a bug where "today" was not converted to the correct time

       Time zone fixes
	   Fixed bug in Date_TimeZone where it didn't recognize +HHMN type
	   time zones.	Thanks to 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

       Test fixes
	   (*) Added test suite!

VERSION 5.06 (1996-10-25)
       New features
	   Added "today at time" formats.

	   ParseDateDelta now normalizes the delta as well as DateCalc.

	   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

	   Parses ctime() date formats (suggested by Matthew R. Sheahan).

	   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

	   (*) Added Date_ConvTZ routine for time zone support.

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

       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

	   Minor improvements to documentation.

	   Documented the 'sort within a sort' bug.

	   Fixed type in documentation/README pointed out by James K. Bence.
