6 Date::Manip::Changes5 - changes in Date::Manip 5.xx
7
9 This describes the changes made to the Date::Manip module in the 5.xx
10 series of releases. Major changes are marked with asterisks (*).
11 For the most part, Date::Manip has remained backward compatible at
13 every release, but occasionally, a change is made which is backward
14 incompatible. These are marked with an exclamation mark (!).
15
18 No changes
19
21 Fully integrated with 6.xx
22 As of Date::Manip 6.14, the 5.xx release is fully integrated into
23 the distribution. Both will be installed automatically and you can
24 switch between them (if you have a recent version of perl). This
25 simplifies the package management process considerably. The
26 downside is that Date::Manip 6.xx will be installed, even if you do
27 not have a recent version of perl and cannot use it.
28
30 Test fixes
31 Fix tests to work better on windows.
32
34 Test fixes
35 Fixed a bug in some of the tests that were causing two tests to
36 fail. JD
37 Explicitly set TZ in all tests to avoid some failures (it got left
39 out of a few when it was bundled with 6.10).
40
42 (*) Combined 5.xx and 6.xx
43 As of 6.10, Date-Manip-6.xx will contain both the Date::Manip 5.xx
44 and 6.xx modules. If perl 5.10 or higher is available, the 6.xx
45 version will be installed. For older versions of perl, the 5.xx
46 version will be installed.
47 This will allow all of the automatic module tools to work
49 correctly.
50 Bug fixes
52 Fixed a bug where years earlier than 1000 AD failed in
53 calculations. John
54 Time zone fixes
56 Improved time zone detection. Stepan Kasal
57 Documentation fixes
59 Minor improvements. Josef Kreulich
60
62 Bug fixes
63 Date_PrevWorkDay and documentation fix. RT #17005
64 I accidentally included a require 5.10 which made Date::Manip not
66 work with earlier versions of perl. Nicholas Riley
67
69 (*) Added time zone abbreviations
70 Date::Manip 5.xx now includes all of the time zone abbreviations
71 from version 6.xx (i.e. all of the abbreviations from the Olsen
72 database).

178 Released
179
181 (!) (*) Recurrences revisited
182 The behavior of some elements of recurrences changed. These
183 included making the week element (N) refer to the Nth occurrence of
184 a day of the week in the week, month, or year. It is now possible
185 to look at the 3rd Friday of every month for example.
186 Y-0-WOY-DOW now refers to the WOY'th occurence of DOW instead of
188 the ISO 8601 date Y-W(WOY)-DOY. Also, changed Y-0-WOY-0 to refer to
189 the WOY'th occurence of FirstDay, and got rid of the MW and MD
190 flags. Many other similar changes.
191 (!) Changed %x format in UnixDate
193 The %x format used to be equivalent to %D (%m/%d/%y), but it has
194 been modified to use the DateFormat config variable, so it may
195 return %d/%m/%y if a non-US DateFormat is specified.
196 New features
198 Added TodayIsMidnight. Reuben Thomas
199 Added "approx" mode to Delta_Format and reversed change to default
201 Delta_Format behavior to the one from version 5.40. Based on

212 Changed taint check to be the one in persec(1). Max Kalika
214 Minor fix so DateInit("VAR=") will work. Thomas Bohme

260
262 Test fixes
263 A quick fix to replace a faulty test.
264
266 Released
267 Number changed to distinguish between the development release
268 (5.41) and the official release.
269
271 As of 5.41, odd numbered releases are development (and appear only on
272 my page). Even number releases are official releases submitted to CPAN.
273 (!) Changed path separator for VMS
275 Since ":" is used in some VMS paths, it should not have been used
276 as the path separator. It has been changed to a newline ("\n")
277 character.
278 (!) Delta_Format behavior changed
280 The entire delta is exact if no month component is present
281 (previously, no year or month component could be present). Due to
282 discussion with Tim Turner.
283 Bug fixes

306 Removed ampersands from function calls in documentation to fit new
308 perl coding standards. Bill Pollock
309 Fixed a bug where spaces in a date caused problems in German (due
311 to the number 1st, 2nd, etc. being 1., 2., etc.). Erik Roderwald

324 dates. Ed Avis
325 Added some help for VMS time zones. Don Slutz
327 Added some checking to the time zone determination. Ed Avis
329 Added time zones. David Coppit, Daniel Serodio, Fabian Mandelbaum,

448 Brian Rectanus
449 Time zone fixes

482 Rewrote IsInt routine based on discussion with Sean Hunter
484 (approximately 30% faster on a SPARC).
485 Time zone fixes
487 Added time zone. Paul Arzul
488 Documentation fixes
490 Fixed a documentation problem with Date_ConvTZ. Diab Jerius
491
493 (!) Deprecated Date_DaysSince999
494 In fixing support for the years 0001-0999, I rewrote
495 Date_DaysSince999 to be Date_DaysSince1BC. The Date_DaysSince999
496 function will be removed.
497 (*) (!) Added PathSep variable
499 In order to better support Win32 platforms, I added the PathSep
500 config variable. This will allow the use of paths such as
501 "c:\date" on Win32 platforms. Old config files on Win32 platforms
502 (which were not working correctly in many cases) may not work if
503 they contain path information to the personal config file.
504 (*) Recurrences now support flags
506 Flags for modifying recurrence dates are now supported.
507 (*) Improved holiday support considerably
509 Added support for recurrences and one-year-only holidays (the
510 latter requested first by Vishal Bhatia.
511 (*) Date_Init improved
513 Date_Init can now return a list of config variables if called in
514 array context. Based on a suggestion by Matt Tuttle.
515 New features
517 Modified Date_GetPrev/Date_GetNext to take $curr=2.
518 Now parses the Apache log file format "dd/mmm/yyyy:hh:mm:ss (time
520 zone)". Mark Ferguson
521 Added OS/2 support. Michael B. Babakov
523 Added Date_IsHoliday routine. Joe Pepin
525 Added recurrence support for Easter (first suggested by Abigail).
527 Bug fixes
529 Made "epoch" not case sensitive and fixed a bug where it would fail
530 in some languages. Caught because of Iosif's thorough Romanian
531 test file.
532 Fixed a problem where "in 5 days/weeks/months" sometimes wouldn't
534 get correctly parsed in other languages. Caught because of Iosif's
535 thorough Romanian test file.
536 Fixed a weakness in ParseDateDelta brought out by the Romanian
538 delta test file.
539 Fixed a bug causing warnings in the beta version of perl. Patch by
541 Paul Johnson.
542 Fixed support for years 0000-0999. Requested by Chris Vaughan
544 Several recurrence bug fixes.
546 Put all the my'ed global variables in a couple hashes to clean up
548 the namespace and to make a few future enhancements easier to do.
549 Fixed a bug where business weeks weren't being used correctly.
551 Qian Miao
552 Fixed a serious typo in the DaysSince1BC routine. Qian Miao
554 Fixed Veteran's day, added Good Friday (off by default). Peter
556 Chen
557 Cleaned up holiday variables and re-did holiday routines.
559 Time zone fixes
561 Added time zones. Oded Cohen
562 Language fixes
564 Added Romanian support (including 2 test files). Iosif Fettich
565 Corrected Swedish translations. Danne Solli
567 Some fixes to German translations. Peter Ehrenberg
569 Added Italian. Nicola Pedrozzi
571 Test fixes
573 Added recurrence test suite
574 Documentation fixes
576 Several documentation updates.
577 New recurrence documentation.
579
581 (!) (*) All Date::Manip variables are no longer accessible
582 Previously, Date::Manip variables were declared using a full
583 package name. Now, they are declared with the my() function. This
584 means that internal variables are no longer accessible outside of
585 the module. Based on suggestion by Tom Christiansen
586 (!) Week interpretation in business mode deltas
588 A business mode delta containing a week value used to be treated as
589 7 days. A much more likely interpretation of a week is Monday to
590 Monday, regardless of holidays, so this is now the behavior.
591 (!) %z UnixDate format
593 The %z UnixDate format used to return the time zone abbreviation.
594 It now returns it as a GMT offset (i.e. -0500). %Z still returns
595 the time zone abbreviation. Suggested by Tuc.
596 (!) Formats "22nd Sunday" returns the intuitive value
598 The date "22nd Sunday" used to return the Sunday of the 22nd week
599 of the year (which could be the 21st, 22nd, or 23rd Sunday of the
600 year depending on how weeks were defined). Now, it returns the
601 22nd Sunday of the year regardless.
602 (!) Separator in DD/YYmmm and mmmDD/YY formats no longer optional
604 Previously, the date "Dec1065" would return Dec 10, 1965. After
605 adding the YYYYmmm and mmmYYYY formats, this was no longer
606 possible. The separator between DD and YY is no longer optional,
607 so
608 Dec1065 returns December 1, 1065
610 Dec10/65 returns December 10, 1965
611 (*) Date_Cmp added
613 In one of the next versions of Date::Manip, the internal format of
614 the date will change to include time zone information. All date
615 comparisons should be made using Date_Cmp (which currently does
616 nothing more than call the Perl "cmp" command, but which will
617 important when comparing dates that include the time zone).
618 Added now in response to a question by Al Sorrell (I should have
620 added it earlier).
621 New features
623 Added exact business mode. Ian Duplisse
624 Added "mmmYYYY" and "YYYYmmm" formats. As a result, "DDYYmmm" and
626 "mmmDDYY" formats changed to "DD/YYmmm" and "mmmDD/YY" as described
627 above. David Twomey
628 Bug fixes
630 Fixed a bug where a date passed in as an array wasn't getting the
631 date removed from the array. Rick Wise
632 Added tests for MPE/iX OS. John Testa
634 Fixed a bug where WorkDayBeg=8:00 went into an infinite loop. Mark
636 Martinec
637 Changed a business week to be the same as an exact week. Abigail
639 Fixed a bug where "Sunday week 0" didn't work (only affected week
641 0) Gerald Rinske
642 Minor bug (my variable declared twice). Paul J. Schinder
644 Fixed a bug where "epoch SECONDS" was getting parsed wrong (for
646 SECONDS which could be interpreted as an ISO-8601 date). N. Thomas
647 Fixed a problem where init files were not being read. Mike Reetz
649 Time zone fixes
651 At the request of the UN, I added the SAT time zone. :-) Howard
652 Hendler
653 Fixed a bug where time zones were converted multiple times if
655 ConvTZ was set and DateCalc called. Steven Hartland
656 Language fixes
658 Added Portuguese. Rui Pedro da Silva Leite Pereira
659 Documentation fixes
661 A number of typos fixed. Ron Pero
662
664 Bug fixes
665 Fixed a bug where "1 month ago" was no longer working (and added it
666 to the test cases). This broke when I fixed the "-1second" bug in
667 the previous version. A result of this is that a number of
668 "deltas" can be parsed as dates (i.e. &ParseDate("1 hour 20 minutes
669 ago") is equivalent to &DateCalc("now","1 hour 20 minutes ago")).
670 Only text deltas can be used in this way (i.e.
671 &ParseDate("-0:0:0:0:1:20:0") will not work).
672 Language fixes
674 Added Spanish support. Bautista Jasso Javier
675
677 (!) Date_Init arguments
678 The old style Date_Init arguments that were deprecated in version
679 5.07 have been removed.
680 (!) (*) DateManip.cnf change
682 Changed .DateManip.cnf to Manip.cnf (to get rid of problems on OS's
683 that insist on 8.3 filenames) for all non-Unix platforms (Windows,
684 VMS, Mac). For all Unix platforms, it's still .DateManip.cnf . It
685 will only look in the user's home directory on VMS and Unix.
686 New features
688 Added "in N days" and "N days ago" formats. Tony Bowden.
689 Added cYYYY format to YYtoYYYY variable. Mark Rejhon.
691 Added 2 days/weeks/months later in both ParseDate and ParseDelta
693 (for Dutch support). Abigail.
694 Added "Y:M:0*-DOM:0:0:0" to ParseRecur. Jeff Yoak.
696 Bug fixes
698 Fixed a bug where the deltas could be off by up to a couple minutes
699 in some rare cases. Herman Horsten.
700 Fixed an "uninitialized symbol" warning. Mark D. Anderson.
702 Fixed a bug where holidays weren't erased. Jonathan Wright.
704 Applied a bug fix from Joe Chapman where the %W/%U UnixDate formats
706 were frequently wrong.
707 Several minor fixes and improvements. Abigail.
709 Added some VMS support. Charles Lane.
711 Fixed a bug which caused a test to fail on some systems. Charles
713 Lane.
714 Fixed a bug where "-1second" was treated as a date rather than a
716 delta in DateCalc. Kenneth Ingham
717 Added a bit to the Makefile.PL (as it was distributed in the Win32
719 Perl Resource Kit). Murray Nesbitt
720 Time zone fixes
722 Allowed time zones of the format STD-#DST-#. Peter Gordon.
723 Added time zone support for "+0500 (EST)". Tom Christiansen.
725 Restricted time zones parsing to 0000-2359 instead of 0000-9999.
727 Frank Cusack
728 Added time zones. W. Phillip Moore, Michael Smith, Samuli
730 Karkkainen
731 Language fixes
733 Added Polish support. Ian Wojtowicz.
734 Added Dutch support. Abigail.
736 Added A.M. and P.M. parsing (not just AM and PM). William W.
738 Arnold.
739 Fixed a German initialization problem. Thomas Horster-Moller and
741 Christian Reithmaier
742 Documentation fixes
744 Documentation fix. Peter Gordon.
745 Minor documentation changes. Yamamoto Hiroshi.
747 Added info about the RCS problem. Supplied by Kipp E. Howard.
749
751 New features
752 Added "epoch SECS" format to ParseDateString. Thanks to: Joshua M.
753 Burgin.
754 Added a patch by Blair Zajac to make Date_NthDayOfYear work with
756 decimal days.
757 Bug fixes
759 Fixed a bug in ParseDateDelta (seems to appear only in 5.005 pre-
760 releases). Found by Larry W. Virden.
761 Missed one form in ParseDate. Noted by Tuc.
763 Fixed a bug where "15:00:00" couldn't be parsed. Michael Pizolato.
765 Split Manip.pm. New files are HISTORY, TODO, Manip.pod.
767 Fixed a bug in ParseDateDelta. Antonio Rosella.
769 Removed the only occurence of $& (which may speed some things up).
771 Fix by Ken Williams. First suggested by Abigail.
772 Fixed an overflow bug in doing date calculations with 2 dates more
774 than 70 years apart. Fix by Vishal Bhatia.
775 Fixed a bug where "5:00pm" wasn't always parsed correctly. Thanks
777 to Jim Trocki.
778 Fixed a bug in UnixDate (it wouldn't return the correct string for
780 a format who's last character was '0') noted by Ramin V.
781 Time zone fixes
783 Relaxed some restrictions on time zones so ISO-8601 dates can use
784 non-ISO-8601 time zones. Noted by John Chambers.
785 Fixed a bug in converting time zones with a minutes field (+1030).
787 Found by Paul O.
788 Language fixes
790 Some fixes to the French translations by Emmanuel Bataille.
791 Added German support. Thanks to Andreas C. Poszvek.
793 Documentation fixes
795 Minor documentation fixes. Will Linden.
796 Fixed a documentation problem with Date_GetPrev. It was still 0-6
798 instead of 1-7. Thanks to Robert Klep.
799
801 (!) (*) Delta format changed
802 A week field has been added to the internal format of the delta.
803 It now reads "Y:M:W:D:H:MN:S" instead of "Y:M:D:H:MN:S".
804 (*) Now handles recurring events
806 Added ParseRecur. First suggested by Chris Jackson.
807 New features
809 All routines can now take either a 2- or 4-digit year.
810 Added Delta_Format. First suggested by Alan Burlison.
812 Added Date_SetDateField. Thanks to Martin Thurn.
814 Bug fixes
816 Made the $err argument to DateCalc optional.
817 Changed the name of several of the library routines (not the
819 callable ones) to standardize naming.
820
822 (!) Long running processes may give incorrect time zone
823 A process that runs during a time zone change (Daylight Saving Time
824 specifically) may report the wrong time zone. See the UpdateCurrTZ
825 variable for more information.
826 (!) UnixDate "%J", "%W", and "%U" formats fixed
828 The %J, %W, and %U will no longer report a week 0 or a week 53 if
829 it should really be week 1 of the following year. They now report
830 the correct week number according to ISO 8601.
831 New features
833 Added YYtoYYYY variable. Suggested by Michel van der List.
834 Added the UpdateCurrTZ variable to increase speed at the cost of
836 being wrong on the time zone.
837 Added British date formats. Thanks to Piran Montford.
839 Monday week
840 today week
841 as well as some US formats
842 in 2 months
843 next month
844 Time can now be written 5pm. Piran Montford.

848 Added UnixDate formats %G and %L to correctly handle the year.
850 Thanks to Samuli Karkkainen.
851 Added ForceDate variable. Based on a suggestion by Christian
853 Campbell.
854 Bug fixes
856 Now passes Taint checks. Thanks to Mike Fuhr, Ron E. Nelson, and
857 Jason L Tibbitts III.
858 Put everything in a "use integer" pragma.
860 Added a missing space in the %g UnixDate format. Thanks to Mike
862 Booth.
863 Removed all mandatory call to Date_Init (only called when current
865 time is required). Significantly faster.
866 Fixed a bug in Date_ConvTZ. Thanks to Patrick K Malone.
868 Fixed a bug in Date_IsWorkDay.
870 Time zone fixes
872 Fixed some Australian time zones. Kim Davies.
873 Language fixes

876 variable.
877 Improved French translations. Thanks to Emmanuel Bataille.
879 Added "Sept" as a recognized abbreviation. Thanks to Martin Thurn.
881 Typo in the French initialization. Thanks to Michel Minsoul.
883 Test fixes
885 Fixed the tests to not fail in 1998.
886 Documentation fixes
888 Documented how to get around Micro$oft problem. Based on a mail by
889 Patrick Stepp.
890
892 (*) ISO 8601 support
893 ISO 8601 dates are now parsed. This resulted in several other
894 changes specified below.
895 (!) (*) ParseDate formats removed
897 As a result of ISO 8601 support, some formats which previously
898 worked may no longer be parsed since they conflict with an ISO 8601
899 format. These include MM-DD-YY (conflicts with YY-MM-DD) and
900 YYMMDD (conflicts with YYYYMM). MM/DD/YY still works, so the first
901 form can be kept easily by changing "-" to "/". YYMMDD can be
902 changed to YY-MM-DD before being parsed. Whenever parsing dates
903 using dashes as separators, they will be treated as ISO 8601 dates.
904 You can get around this by converting all dashes to slashes.
905 (!) (*) Week day numbering
907 The day numbering was changed from 0-6 (Sun-Sat) to 1-7 (Mon-Sun)
908 to be ISO 8601 compatible. Weeks start on Monday (though this can
909 be overridden using the FirstDay config variable) and the 1st week
910 of the year contains Jan 4 (though it can be forced to contain Jan
911 1 with the Jan1Week1 config variable).
912 New features
914 Several new parsing formats added, including:
915 "Friday" suggested by Rob Perelman
916 "12th" suggested by Rob Perelman
917 "last day of MONTH" suggested by Chadd Westhoff
918 Added ParseDateString for speed (and simplicity for modifying
920 ParseDate)
921 Added %J and %K formats to UnixDate.
923 Added Date_DaysInMonth.
925 Bug fixes
927 Reorganized ParseDate more efficiently.
928 Fixed some incorrect uses of $in instead of $future in ParseDate.
930 Thanks to Erik Corry.
931 Added some speedups (more to come).
933 Test fixes
935 Cleaned up testing mechanism a bit and added tests for ISO 8601
936 formats.
937
939 Version 5.11 was never released to CPAN.
940 Bug fixes
942 Added one more check for NT perl. Thanks to Rodney Haywood.
943 Added some comments to help me keep my personal libraries up-to-
945 date with respect to Date::Manip and vice-versa.
946 Fixed a bug which showed up in French dates (though it could happen
948 in other languages as well). Thanks to Georges Martin.
949 Fixed a bug in DateCalc. Thanks to Thomas Winzig.
951 Removed the "eval" statement from CheckFilePath which causes a suid
953 c wrapper program to die when it calls a Date::Manip script.
954 Thanks to Hank Hughes.
955 Fixed a bug in business mode calculations. Thanks to Sterling
957 Swartwout.
958 Fixed a bug in which "1997023100:00:00" was accepted as valid.
960 Thanks to Doug Emerald.
961 Fixed a bug in which ConvTZ was not used correctly in ParseDate.
963 Re-did portions of Date_ConvTZ. Thanks to Vivek Khera.

973 Added time zones. Paul Gillingwater, Rosella Antonio, Kang Taewook
974
976 Bug fixes
977 Cleaned up In, At, and On regexps.
978 Added 2 checks for MSWin32 (date command and getpw* didn't work).
980 Thanks to Alan Humphrey.
981 Fixed two bugs in the DateCalc routines. Pointed out by Kevin
983 Baker.
984 Added a check for Windows_95. Thanks to Charlie W.
986 Cleaned up checks for MacOS and Microsoft OS's. Hopefully I'm
988 catching everything. Thanks to Charlie Wu for one more check.
989 Fixed a typo which broke Time%Date (Date=dd%mmm%yy) format. Thanks
991 to Timothy Kimball.
992 Time zone fixes
994 Fixed some problems with how "US/Eastern" type time zones were
995 used. Thanks to Marvin Solomon.
996 Test fixes
998 Tests will now run regardless of the time zone you are in.
999 Test will always read the DateManip.cnf file in t/ now.
1001 A failed test will now give slightly more information.
1003 DateManip.cnf file in t/ now sets ALL options to override any
1005 changes made in the Manip.pm file.
1006 Documentation fixes
1008 Added documentation for backwards incompatibilities to POD.
1009 Fixed some problems in POD documentation. Thanks to Marvin
1011 Solomon.
1012 Fixed minor POD error pointed out by John Perkins.
1014 Changed documentation for Date_IsWorkDay (it was quite confusing
1016 using a variable named $time). Thanks to Erik M. Schwartz.
1017 Fixed typo in documentation (midnight misspelled). Thanks to
1019 Timothy Kimball.
1020
1022 Bug fixes
1023 Upgraded to 5.003_23 and fixed one problem associated with it.
1024 Used carp and changed all die's to confess.
1026 Replaced some UNIX commands with perl equivalents (date with
1028 localtime in the tests, pwd with cwd in the path routines).
1029 Cleaned up all routines working with the path.
1031 Test fixes
1033 Tests work again (broke in 5.08). Thanks to Alex Lewin and Michael
1034 Fuhr for running debugging tests.
1035
1037 Bug fixes
1038 (*) Fixed serious bug in ConvTZ pointed out by David Hall.
1039 (*) Modified Date_ConvTZ (and documented it).
1041
1043 Released two patches for 5.07.
1044 Bug fixes
1046 Fixed a bug where a delta component of "-0" would mess things up.
1047 Reported by Nigel Chapman.
1048 Time zone fixes
1050 (*) Can now understand PST8PDT type zones (but only in
1051 Date_TimeZone).
1052 Added lots of time zone abbreviations.
1054 Test fixes
1056 Fixed some tests (good for another year).
1057
1059 (!) UnixDate "%s" format
1060 Used to return the number of seconds since 1/1/1970 in the current
1061 time zone. It now returns the number of seconds since 1/1/1970
1062 GMT. The "%o" format was added which returns what "%s" previously
1063 did.
1064 (!) (*) Internal format of delta
1066 The format for the deltas returned by ParseDateDelta changed.
1067 Previously, each element of a delta had a sign attached to it
1068 (+1:+2:+3:+4:+5:+6). The new format removes all unnecessary signs
1069 by default (+1:2:3:4:5:6). Also, because of the way deltas are
1070 normalized (see documentation on ParseDateDelta), at most two signs
1071 are included. For backwards compatibility, the config variable
1072 DeltaSigns was added. If set to 1, all deltas include all 6 signs.
1073 (!) (*) Date_Init arguments
1075 The format of the Date_Init calling arguments changed. The old
1076 method
1077 Date_Init($language,$format,$tz,$convtz);
1079 is still supported , but this support will likely disappear in the
1081 future. Use the new calling format instead:
1082 Date_Init("var=val","var=val",...);
1084 NOTE: The old format is no longer supported as of version 5.32 .
1086 (*) Added weeks to ParseDateDelta.
1088 Suggested by Mike Bassman. Note that since this is a late
1089 addition, I did not change the internal format of a delta.
1090 Instead, it is added to the days field.
1091 (*) Now reads a config file.
1093 Refer to the Date_Init documentation for details.
1094 (*) Added business mode.
1096 See documentation. Suggested by Mike Bassman.
1097 New features
1099 (*) Modified how deltas are normalized and added the DeltaSigns
1100 config variable.
1101 Added %q format "YYYYMMDDHHMMSS" to UnixDate. Requested by Rob
1103 Perelman. Also added %P format "YYYYMMDDHH:MM:SS".
1104 Added a new config variable to allow you to work with multiple
1106 internal formats (with and without colons). Requested by Rob
1107 Perelman. See Date_Init documentation.
1108 Added the following formats suggested by Andreas Johansson:
1110 Sunday week 22 [in 1996] [at 12:00]
1111 22nd Sunday [in 1996] [at 12:00]
1112 Sunday 22nd week [in 1996] [at 12:00]
1113 Added a new config variable to allow you to define the first day of
1115 the week. See Date_Init documentation.
1116 Added the following formats to ParseDate for convenience (some were
1118 suggested by Mike Bassman):
1119 next/last Friday [at time]
1120 next/last week [at time]
1121 in 2 weeks [at time]
1122 2 weeks ago [at time]
1123 Friday in 2 weeks
1124 in 2 weeks on Friday
1125 Friday 2 weeks ago
1126 2 weeks ago Friday
1127 Added Date_SecsSince1970GMT, moved the %s format to %o (secs since
1129 1/1/70) and added %s format (secs since 1/1/70 GMT). Based on
1130 suggestions by Mark Osbourne. Note this introduces a minor
1131 backward incompatibility described above.
1132 Date_SetTime now works with international time separators.
1134 Added the %g format (%a, %d %b %Y %H:%M:%S %z) for an RFC 1123
1136 date. Suggested by Are Bryne.
1137 Added options to delete existing holidays and ignore global config
1139 file.
1140 Date_GetNext and Date_GetPrev now return the next/prev occurence of
1142 a time as well as a day. Suggested by Are Bryne.
1143 In approximate mode, deltas now come out completely normalized
1145 (only 1 sign). Suggested by Rob Perelman.
1146 Added Date::Manip::InitDone so initialization isn't duplicated.
1148 Added a 3rd internal format to store YYYY-MM-DD HH:MN:SS (iso
1150 8601).
1151 Added a config variable to allow you to work with 24 hour business
1153 days. Suggested by Mike Bassman.
1154 ParseDateDelta now returns "" rather than "+0:0:0:0:0:0" when there
1156 is an error.
1157 Bug fixes
1159 (*) The d:h:mn:s of ALL deltas are normalized.
1160 Huge number of code changes to clean things up.
1162 Subroutines now check to see if 4 digit years are entered.
1164 Suggested by Are Bryne.
1165 Added local($_) to all routines which use $_. Suggested by Rob
1167 Perelman.
1168 Complete rewrite of DateCalc.
1170 Fixed a bug where UnixDate %E format didn't work with single digit
1172 dates. Patch supplied by Jyrgen Nyrgaard.
1173 Fixed a bug where "today" was not converted to the correct time
1175 zone.
1176 Time zone fixes
1178 Fixed bug in Date_TimeZone where it didn't recognize +HHMN type
1179 time zones. Thanks to Are Bryne.
1180 Added WindowsNT check to Date_TimeZone to get around NT's weird
1182 date command. Thanks to Are Bryne.
1183 Fixed typo (CSD instead of CST).
1185 Fixed sign in military time zones making Date::Manip RFC 1123
1187 compliant (except that time zone information is not stored in any
1188 format)
1189 Test fixes
1191 (*) Added test suite!
1192
1194 New features
1195 Added "today at time" formats.
1196 ParseDateDelta now normalizes the delta as well as DateCalc.
1198 Added %Q format "YYYYMMDD" to UnixDate. Requested by Rob Perelman.
1200 Bug fixes
1202 Fixed another two places where a variable was declared twice using
1203 my (thanks to Ric Steinberger).
1204 Fixed a bug where fractional seconds weren't parsed correctly.
1206 Fixed a bug where "noon" and other special times were not parsed in
1208 the "which day of month" formats.
1209 Fixed a minor bug where a few matches were case sensitive.
1211 The command "date +%Z" doesn't work on SunOS machines (and perhaps
1213 others) so 5.05 is effectively broken. 5.06 released to fix this.
1214 Reported by Rob Perelman.
1215
1217 New features
1218 Changed deltas to be all positive or all negative when produced by
1219 DateCalc. Suggested by Steve Braun
1220 Added DateManipVersion routine.
1222 (*) Parses RFC 822 dates (thanks to J.B. Nicholson-Owens for
1224 suggestion).
1225 Parses ctime() date formats (suggested by Matthew R. Sheahan).
1227 Now supports times like "noon" and "midnight".
1229 Bug fixes
1231 Fixed bug introduced in 5.04 when default day set to 1. When no
1232 date given, have day default to today rather than 1. It only
1233 defaults to one if a partial date is given.
1234 Fixed bug where Date_DaysSince999 returned the wrong value (the
1236 error did not affect any other functions in Date::Manip due to the
1237 way it was called and the nature of the error). Pointed out by
1238 Jason Baker
1239 Dates with commas in them are now read properly.
1241 Fixed two places where a variable was declared twice using my
1243 (thanks to Ric Steinberger).
1244 Hopefully fixed installation problems.
1246 Got rid of the last (I think) couple of US specific strings.
1248 Fixed bug in Date_SetTime (didn't work with $hr,$min,$sec < 10).
1250 Added ModuloAddition routine and simplified DateCalc.
1252 Time zone fixes
1254 (*) Now supports time zones.
1255 (*) Added Date_ConvTZ routine for time zone support.
1257 Date_TimeZone will now also check `date '+%Z'` suggested by Aharon
1259 Schkolnik.
1260 Language fixes
1262 Added Swedish translation (thanks to Andreas Johansson
1263 The time separators are now language specific so the French can
1265 write "10h30" and the Swedes can write "10.30". Suggested by
1266 Andreas Johansson.
1267 Documentation fixes
1269 Fixed bad mistake in documentation (use Date::Manip instead of use
1270 DateManip) pointed out by tuc@valhalla.stormking.com
1271 Minor improvements to documentation.
1273 Documented the 'sort within a sort' bug.
1275 Fixed type in documentation/README pointed out by James K. Bence.

1282 Bug fixes
1284 Fixed bugs reported by J.B. Nicholson-Owens
1285 "Tue Jun 25 1996" wasn't parsed correctly (regexp was case
1286 sensitive)
1287 full day names not parsed correctly
1288 the default day in ErrorCheck should be 1, NOT currd since when
1289 currd>28, it may not be a valid date for the month
1290
1292 Bug fixes
1293 Fixed a couple of bugs in UnixDate.
1294 Declared package variables to avoid warning "Identifier XXX used
1296 only once". Thanks to Peter Bray for the suggestion.
1297
1299 New features
1300 (*) Added some internationalization (most of the routines had to be
1301 modified at least slightly)
1302 Bug fixes
