Date::Manip::Changes5(3) User Contributed Perl Documentation Date::Manip::Changes5(3)
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.

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

Released
Number changed to distinguish between the development release (5.41) and the official
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

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.

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.
Bug fixes

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.

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.

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

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).

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.

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.

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.

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.
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 zone.
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 format)
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 DateCalc.
Suggested by Steve Braun
Added DateManipVersion routine.
(*) Parses RFC 822 dates (thanks to J.B. Nicholson-Owens for suggestion).
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
(*) 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 AT valhalla.com
Minor improvements to documentation.
Documented the 'sort within a sort' bug.
Fixed type in documentation/README pointed out by James K. Bence.
