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
17 As of December 2012, Version 5 of Date::Manip will no longer be
18 modified. It is expected that version 5.64 will be the final release.
19 The one exception is that if someone submits a patch that applies
21 cleanly and causes zero failures in the test suite, I will consider
22 adding it on a case-by-cast bases.
23 Please use Date::Manip 6.xx instead.
25
27 Better handling of '0000' timezone
28 Applied a patch supplied by Ed Avis that improves handling of the
29 '0000' timezone..
30
32 Fixed business mode calculation
33 Applied a patch that I received some time ago to fix a business
34 mode calculation. Steve Tempest

40 No changes
41
43 Fully integrated with 6.xx
44 As of Date::Manip 6.14, the 5.xx release is fully integrated into
45 the distribution. Both will be installed automatically and you can
46 switch between them (if you have a recent version of perl). This
47 simplifies the package management process considerably. The
48 downside is that Date::Manip 6.xx will be installed, even if you do
49 not have a recent version of perl and cannot use it.
50
52 Test fixes
53 Fix tests to work better on windows.
54
56 Test fixes
57 Fixed a bug in some of the tests that were causing two tests to
58 fail. JD
59 Explicitly set TZ in all tests to avoid some failures (it got left
61 out of a few when it was bundled with 6.10).
62
64 (*) Combined 5.xx and 6.xx
65 As of 6.10, Date-Manip-6.xx will contain both the Date::Manip 5.xx
66 and 6.xx modules. If perl 5.10 or higher is available, the 6.xx
67 version will be installed. For older versions of perl, the 5.xx
68 version will be installed.
69 This will allow all of the automatic module tools to work
71 correctly.
72 Bug fixes
74 Fixed a bug where years earlier than 1000 AD failed in
75 calculations. John

84 Bug fixes
85 Date_PrevWorkDay and documentation fix. RT #17005
86 I accidentally included a require 5.10 which made Date::Manip not
88 work with earlier versions of perl. Nicholas Riley
89
91 (*) Added time zone abbreviations
92 Date::Manip 5.xx now includes all of the time zone abbreviations
93 from version 6.xx (i.e. all of the abbreviations from the Olsen
94 database).

200 Released
201
203 (!) (*) Recurrences revisited
204 The behavior of some elements of recurrences changed. These
205 included making the week element (N) refer to the Nth occurrence of
206 a day of the week in the week, month, or year. It is now possible
207 to look at the 3rd Friday of every month for example.
208 Y-0-WOY-DOW now refers to the WOY'th occurence of DOW instead of
210 the ISO 8601 date Y-W(WOY)-DOY. Also, changed Y-0-WOY-0 to refer to
211 the WOY'th occurence of FirstDay, and got rid of the MW and MD
212 flags. Many other similar changes.
213 (!) Changed %x format in UnixDate
215 The %x format used to be equivalent to %D (%m/%d/%y), but it has
216 been modified to use the DateFormat config variable, so it may
217 return %d/%m/%y if a non-US DateFormat is specified.
218 New features
220 Added TodayIsMidnight. Reuben Thomas
221 Added "approx" mode to Delta_Format and reversed change to default
223 Delta_Format behavior to the one from version 5.40. Based on

286
288 Released
289 Number changed to distinguish between the development release
290 (5.41) and the official release.
291
293 As of 5.41, odd numbered releases are development (and appear only on
294 my page). Even number releases are official releases submitted to CPAN.
295 (!) Changed path separator for VMS
297 Since ":" is used in some VMS paths, it should not have been used
298 as the path separator. It has been changed to a newline ("\n")
299 character.
300 (!) Delta_Format behavior changed
302 The entire delta is exact if no month component is present
303 (previously, no year or month component could be present). Due to
304 discussion with Tim Turner.
305 Bug fixes

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

507 Time zone fixes
509 Added time zone. Paul Arzul
510 Documentation fixes
512 Fixed a documentation problem with Date_ConvTZ. Diab Jerius
513
515 (!) Deprecated Date_DaysSince999
516 In fixing support for the years 0001-0999, I rewrote
517 Date_DaysSince999 to be Date_DaysSince1BC. The Date_DaysSince999
518 function will be removed.
519 (*) (!) Added PathSep variable
521 In order to better support Win32 platforms, I added the PathSep
522 config variable. This will allow the use of paths such as
523 "c:\date" on Win32 platforms. Old config files on Win32 platforms
524 (which were not working correctly in many cases) may not work if
525 they contain path information to the personal config file.
526 (*) Recurrences now support flags
528 Flags for modifying recurrence dates are now supported.
529 (*) Improved holiday support considerably
531 Added support for recurrences and one-year-only holidays (the
532 latter requested first by Vishal Bhatia.
533 (*) Date_Init improved
535 Date_Init can now return a list of config variables if called in
536 array context. Based on a suggestion by Matt Tuttle.
537 New features
539 Modified Date_GetPrev/Date_GetNext to take $curr=2.
540 Now parses the Apache log file format "dd/mmm/yyyy:hh:mm:ss (time
542 zone)". Mark Ferguson
543 Added OS/2 support. Michael B. Babakov
545 Added Date_IsHoliday routine. Joe Pepin
547 Added recurrence support for Easter (first suggested by Abigail).
549 Bug fixes
551 Made "epoch" not case sensitive and fixed a bug where it would fail
552 in some languages. Caught because of Iosif's thorough Romanian
553 test file.
554 Fixed a problem where "in 5 days/weeks/months" sometimes wouldn't
556 get correctly parsed in other languages. Caught because of Iosif's
557 thorough Romanian test file.
558 Fixed a weakness in ParseDateDelta brought out by the Romanian
560 delta test file.
561 Fixed a bug causing warnings in the beta version of perl. Patch by
563 Paul Johnson.
564 Fixed support for years 0000-0999. Requested by Chris Vaughan
566 Several recurrence bug fixes.
568 Put all the my'ed global variables in a couple hashes to clean up
570 the namespace and to make a few future enhancements easier to do.
571 Fixed a bug where business weeks weren't being used correctly.
573 Qian Miao
574 Fixed a serious typo in the DaysSince1BC routine. Qian Miao
576 Fixed Veteran's day, added Good Friday (off by default). Peter
578 Chen
579 Cleaned up holiday variables and re-did holiday routines.
581 Time zone fixes
583 Added time zones. Oded Cohen
584 Language fixes
586 Added Romanian support (including 2 test files). Iosif Fettich
587 Corrected Swedish translations. Danne Solli
589 Some fixes to German translations. Peter Ehrenberg
591 Added Italian. Nicola Pedrozzi
593 Test fixes
595 Added recurrence test suite
596 Documentation fixes
598 Several documentation updates.
599 New recurrence documentation.
601
603 (!) (*) All Date::Manip variables are no longer accessible
604 Previously, Date::Manip variables were declared using a full
605 package name. Now, they are declared with the my() function. This
606 means that internal variables are no longer accessible outside of
607 the module. Based on suggestion by Tom Christiansen
608 (!) Week interpretation in business mode deltas
610 A business mode delta containing a week value used to be treated as
611 7 days. A much more likely interpretation of a week is Monday to
612 Monday, regardless of holidays, so this is now the behavior.
613 (!) %z UnixDate format
615 The %z UnixDate format used to return the time zone abbreviation.
616 It now returns it as a GMT offset (i.e. -0500). %Z still returns
617 the time zone abbreviation. Suggested by Tuc.
618 (!) Formats "22nd Sunday" returns the intuitive value
620 The date "22nd Sunday" used to return the Sunday of the 22nd week
621 of the year (which could be the 21st, 22nd, or 23rd Sunday of the
622 year depending on how weeks were defined). Now, it returns the
623 22nd Sunday of the year regardless.
624 (!) Separator in DD/YYmmm and mmmDD/YY formats no longer optional
626 Previously, the date "Dec1065" would return Dec 10, 1965. After
627 adding the YYYYmmm and mmmYYYY formats, this was no longer
628 possible. The separator between DD and YY is no longer optional,
629 so
630 Dec1065 returns December 1, 1065
632 Dec10/65 returns December 10, 1965
633 (*) Date_Cmp added
635 In one of the next versions of Date::Manip, the internal format of
636 the date will change to include time zone information. All date
637 comparisons should be made using Date_Cmp (which currently does
638 nothing more than call the Perl "cmp" command, but which will
639 important when comparing dates that include the time zone).
640 Added now in response to a question by Al Sorrell (I should have
642 added it earlier).
643 New features
645 Added exact business mode. Ian Duplisse
646 Added "mmmYYYY" and "YYYYmmm" formats. As a result, "DDYYmmm" and
648 "mmmDDYY" formats changed to "DD/YYmmm" and "mmmDD/YY" as described
649 above. David Twomey
650 Bug fixes
652 Fixed a bug where a date passed in as an array wasn't getting the
653 date removed from the array. Rick Wise
654 Added tests for MPE/iX OS. John Testa
656 Fixed a bug where WorkDayBeg=8:00 went into an infinite loop. Mark
658 Martinec
659 Changed a business week to be the same as an exact week. Abigail
661 Fixed a bug where "Sunday week 0" didn't work (only affected week
663 0) Gerald Rinske
664 Minor bug (my variable declared twice). Paul J. Schinder
666 Fixed a bug where "epoch SECONDS" was getting parsed wrong (for
668 SECONDS which could be interpreted as an ISO-8601 date). N. Thomas
669 Fixed a problem where init files were not being read. Mike Reetz
671 Time zone fixes
673 At the request of the UN, I added the SAT time zone. :-) Howard
674 Hendler
675 Fixed a bug where time zones were converted multiple times if
677 ConvTZ was set and DateCalc called. Steven Hartland
678 Language fixes
680 Added Portuguese. Rui Pedro da Silva Leite Pereira
681 Documentation fixes
683 A number of typos fixed. Ron Pero
684
686 Bug fixes
687 Fixed a bug where "1 month ago" was no longer working (and added it
688 to the test cases). This broke when I fixed the "-1second" bug in
689 the previous version. A result of this is that a number of
690 "deltas" can be parsed as dates (i.e. &ParseDate("1 hour 20 minutes
691 ago") is equivalent to &DateCalc("now","1 hour 20 minutes ago")).
692 Only text deltas can be used in this way (i.e.
693 &ParseDate("-0:0:0:0:1:20:0") will not work).
694 Language fixes
696 Added Spanish support. Bautista Jasso Javier
697
699 (!) Date_Init arguments
700 The old style Date_Init arguments that were deprecated in version
701 5.07 have been removed.
702 (!) (*) DateManip.cnf change
704 Changed .DateManip.cnf to Manip.cnf (to get rid of problems on OS's
705 that insist on 8.3 filenames) for all non-Unix platforms (Windows,
706 VMS, Mac). For all Unix platforms, it's still .DateManip.cnf . It
707 will only look in the user's home directory on VMS and Unix.
708 New features
710 Added "in N days" and "N days ago" formats. Tony Bowden.
711 Added cYYYY format to YYtoYYYY variable. Mark Rejhon.
713 Added 2 days/weeks/months later in both ParseDate and ParseDelta
715 (for Dutch support). Abigail.
716 Added "Y:M:0*-DOM:0:0:0" to ParseRecur. Jeff Yoak.
718 Bug fixes
720 Fixed a bug where the deltas could be off by up to a couple minutes
721 in some rare cases. Herman Horsten.
722 Fixed an "uninitialized symbol" warning. Mark D. Anderson.
724 Fixed a bug where holidays weren't erased. Jonathan Wright.
726 Applied a bug fix from Joe Chapman where the %W/%U UnixDate formats
728 were frequently wrong.
729 Several minor fixes and improvements. Abigail.
731 Added some VMS support. Charles Lane.
733 Fixed a bug which caused a test to fail on some systems. Charles
735 Lane.
736 Fixed a bug where "-1second" was treated as a date rather than a
738 delta in DateCalc. Kenneth Ingham
739 Added a bit to the Makefile.PL (as it was distributed in the Win32
741 Perl Resource Kit). Murray Nesbitt
742 Time zone fixes
744 Allowed time zones of the format STD-#DST-#. Peter Gordon.
745 Added time zone support for "+0500 (EST)". Tom Christiansen.
747 Restricted time zones parsing to 0000-2359 instead of 0000-9999.
749 Frank Cusack
750 Added time zones. W. Phillip Moore, Michael Smith, Samuli
752 Karkkainen
753 Language fixes
755 Added Polish support. Ian Wojtowicz.
756 Added Dutch support. Abigail.
758 Added A.M. and P.M. parsing (not just AM and PM). William W.
760 Arnold.
761 Fixed a German initialization problem. Thomas Horster-Moller and
763 Christian Reithmaier
764 Documentation fixes
766 Documentation fix. Peter Gordon.
767 Minor documentation changes. Yamamoto Hiroshi.
769 Added info about the RCS problem. Supplied by Kipp E. Howard.
771
773 New features
774 Added "epoch SECS" format to ParseDateString. Thanks to: Joshua M.
775 Burgin.
776 Added a patch by Blair Zajac to make Date_NthDayOfYear work with
778 decimal days.
779 Bug fixes
781 Fixed a bug in ParseDateDelta (seems to appear only in 5.005 pre-
782 releases). Found by Larry W. Virden.
783 Missed one form in ParseDate. Noted by Tuc.
785 Fixed a bug where "15:00:00" couldn't be parsed. Michael Pizolato.
787 Split Manip.pm. New files are HISTORY, TODO, Manip.pod.
789 Fixed a bug in ParseDateDelta. Antonio Rosella.
791 Removed the only occurence of $& (which may speed some things up).
793 Fix by Ken Williams. First suggested by Abigail.
794 Fixed an overflow bug in doing date calculations with 2 dates more
796 than 70 years apart. Fix by Vishal Bhatia.
797 Fixed a bug where "5:00pm" wasn't always parsed correctly. Thanks
799 to Jim Trocki.
800 Fixed a bug in UnixDate (it wouldn't return the correct string for
802 a format who's last character was '0') noted by Ramin V.
803 Time zone fixes
805 Relaxed some restrictions on time zones so ISO-8601 dates can use
806 non-ISO-8601 time zones. Noted by John Chambers.
807 Fixed a bug in converting time zones with a minutes field (+1030).
809 Found by Paul O.
810 Language fixes
812 Some fixes to the French translations by Emmanuel Bataille.
813 Added German support. Thanks to Andreas C. Poszvek.
815 Documentation fixes
817 Minor documentation fixes. Will Linden.
818 Fixed a documentation problem with Date_GetPrev. It was still 0-6
820 instead of 1-7. Thanks to Robert Klep.
821
823 (!) (*) Delta format changed
824 A week field has been added to the internal format of the delta.
825 It now reads "Y:M:W:D:H:MN:S" instead of "Y:M:D:H:MN:S".
826 (*) Now handles recurring events
828 Added ParseRecur. First suggested by Chris Jackson.
829 New features
831 All routines can now take either a 2- or 4-digit year.
832 Added Delta_Format. First suggested by Alan Burlison.
834 Added Date_SetDateField. Thanks to Martin Thurn.
836 Bug fixes
838 Made the $err argument to DateCalc optional.
839 Changed the name of several of the library routines (not the
841 callable ones) to standardize naming.
842
844 (!) Long running processes may give incorrect time zone
845 A process that runs during a time zone change (Daylight Saving Time
846 specifically) may report the wrong time zone. See the UpdateCurrTZ
847 variable for more information.
848 (!) UnixDate "%J", "%W", and "%U" formats fixed
850 The %J, %W, and %U will no longer report a week 0 or a week 53 if
851 it should really be week 1 of the following year. They now report
852 the correct week number according to ISO 8601.
853 New features
855 Added YYtoYYYY variable. Suggested by Michel van der List.
856 Added the UpdateCurrTZ variable to increase speed at the cost of
858 being wrong on the time zone.
859 Added British date formats. Thanks to Piran Montford.
861 Monday week
862 today week
863 as well as some US formats
864 in 2 months
865 next month
866 Time can now be written 5pm. Piran Montford.
868 Added the TomorrowFirst variable and Date_NearestWorkDay function.
870 Added UnixDate formats %G and %L to correctly handle the year.
872 Thanks to Samuli Karkkainen.
873 Added ForceDate variable. Based on a suggestion by Christian
875 Campbell.
876 Bug fixes
878 Now passes Taint checks. Thanks to Mike Fuhr, Ron E. Nelson, and
879 Jason L Tibbitts III.
880 Put everything in a "use integer" pragma.
882 Added a missing space in the %g UnixDate format. Thanks to Mike
884 Booth.
885 Removed all mandatory call to Date_Init (only called when current
887 time is required). Significantly faster.
888 Fixed a bug in Date_ConvTZ. Thanks to Patrick K Malone.
890 Fixed a bug in Date_IsWorkDay.
892 Time zone fixes
894 Fixed some Australian time zones. Kim Davies.
895 Language fixes

898 variable.
899 Improved French translations. Thanks to Emmanuel Bataille.
901 Added "Sept" as a recognized abbreviation. Thanks to Martin Thurn.
903 Typo in the French initialization. Thanks to Michel Minsoul.
905 Test fixes
907 Fixed the tests to not fail in 1998.
908 Documentation fixes
910 Documented how to get around Micro$oft problem. Based on a mail by
911 Patrick Stepp.
912
914 (*) ISO 8601 support
915 ISO 8601 dates are now parsed. This resulted in several other
916 changes specified below.
917 (!) (*) ParseDate formats removed
919 As a result of ISO 8601 support, some formats which previously
920 worked may no longer be parsed since they conflict with an ISO 8601
921 format. These include MM-DD-YY (conflicts with YY-MM-DD) and
922 YYMMDD (conflicts with YYYYMM). MM/DD/YY still works, so the first
923 form can be kept easily by changing "-" to "/". YYMMDD can be
924 changed to YY-MM-DD before being parsed. Whenever parsing dates
925 using dashes as separators, they will be treated as ISO 8601 dates.
926 You can get around this by converting all dashes to slashes.
927 (!) (*) Week day numbering
929 The day numbering was changed from 0-6 (Sun-Sat) to 1-7 (Mon-Sun)
930 to be ISO 8601 compatible. Weeks start on Monday (though this can
931 be overridden using the FirstDay config variable) and the 1st week
932 of the year contains Jan 4 (though it can be forced to contain Jan
933 1 with the Jan1Week1 config variable).
934 New features
936 Several new parsing formats added, including:
937 "Friday" suggested by Rob Perelman
938 "12th" suggested by Rob Perelman
939 "last day of MONTH" suggested by Chadd Westhoff
940 Added ParseDateString for speed (and simplicity for modifying
942 ParseDate)
943 Added %J and %K formats to UnixDate.
945 Added Date_DaysInMonth.
947 Bug fixes
949 Reorganized ParseDate more efficiently.
950 Fixed some incorrect uses of $in instead of $future in ParseDate.
952 Thanks to Erik Corry.
953 Added some speedups (more to come).
955 Test fixes
957 Cleaned up testing mechanism a bit and added tests for ISO 8601
958 formats.
959
961 Version 5.11 was never released to CPAN.
962 Bug fixes
964 Added one more check for NT perl. Thanks to Rodney Haywood.
965 Added some comments to help me keep my personal libraries up-to-
967 date with respect to Date::Manip and vice-versa.
968 Fixed a bug which showed up in French dates (though it could happen
970 in other languages as well). Thanks to Georges Martin.
971 Fixed a bug in DateCalc. Thanks to Thomas Winzig.
973 Removed the "eval" statement from CheckFilePath which causes a suid
975 c wrapper program to die when it calls a Date::Manip script.
976 Thanks to Hank Hughes.
977 Fixed a bug in business mode calculations. Thanks to Sterling
979 Swartwout.
980 Fixed a bug in which "1997023100:00:00" was accepted as valid.
982 Thanks to Doug Emerald.
983 Fixed a bug in which ConvTZ was not used correctly in ParseDate.
985 Re-did portions of Date_ConvTZ. Thanks to Vivek Khera.

988 Added $^X check for Win95 perl. Thanks to Walter Soldierer.
990 Missed one call to NormalizeDelta so the output was wrong. Thanks
992 to Brad A. Buikema.
993 Time zone fixes
995 Added time zones. Paul Gillingwater, Rosella Antonio, Kang Taewook
996
998 Bug fixes
999 Cleaned up In, At, and On regexps.
1000 Added 2 checks for MSWin32 (date command and getpw* didn't work).
1002 Thanks to Alan Humphrey.
1003 Fixed two bugs in the DateCalc routines. Pointed out by Kevin
1005 Baker.
1006 Added a check for Windows_95. Thanks to Charlie W.
1008 Cleaned up checks for MacOS and Microsoft OS's. Hopefully I'm
1010 catching everything. Thanks to Charlie Wu for one more check.
1011 Fixed a typo which broke Time%Date (Date=dd%mmm%yy) format. Thanks
1013 to Timothy Kimball.
1014 Time zone fixes
1016 Fixed some problems with how "US/Eastern" type time zones were
1017 used. Thanks to Marvin Solomon.
1018 Test fixes
1020 Tests will now run regardless of the time zone you are in.
1021 Test will always read the DateManip.cnf file in t/ now.
1023 A failed test will now give slightly more information.
1025 DateManip.cnf file in t/ now sets ALL options to override any
1027 changes made in the Manip.pm file.
1028 Documentation fixes
1030 Added documentation for backwards incompatibilities to POD.
1031 Fixed some problems in POD documentation. Thanks to Marvin
1033 Solomon.
1034 Fixed minor POD error pointed out by John Perkins.
1036 Changed documentation for Date_IsWorkDay (it was quite confusing
1038 using a variable named $time). Thanks to Erik M. Schwartz.
1039 Fixed typo in documentation (midnight misspelled). Thanks to
1041 Timothy Kimball.
1042
1044 Bug fixes
1045 Upgraded to 5.003_23 and fixed one problem associated with it.
1046 Used carp and changed all die's to confess.
1048 Replaced some UNIX commands with perl equivalents (date with
1050 localtime in the tests, pwd with cwd in the path routines).
1051 Cleaned up all routines working with the path.
1053 Test fixes
1055 Tests work again (broke in 5.08). Thanks to Alex Lewin and Michael
1056 Fuhr for running debugging tests.
1057
1059 Bug fixes
1060 (*) Fixed serious bug in ConvTZ pointed out by David Hall.
1061 (*) Modified Date_ConvTZ (and documented it).
1063
1065 Released two patches for 5.07.
1066 Bug fixes
1068 Fixed a bug where a delta component of "-0" would mess things up.
1069 Reported by Nigel Chapman.
1070 Time zone fixes
1072 (*) Can now understand PST8PDT type zones (but only in
1073 Date_TimeZone).
1074 Added lots of time zone abbreviations.
1076 Test fixes
1078 Fixed some tests (good for another year).
1079
1081 (!) UnixDate "%s" format
1082 Used to return the number of seconds since 1/1/1970 in the current
1083 time zone. It now returns the number of seconds since 1/1/1970
1084 GMT. The "%o" format was added which returns what "%s" previously
1085 did.
1086 (!) (*) Internal format of delta
1088 The format for the deltas returned by ParseDateDelta changed.
1089 Previously, each element of a delta had a sign attached to it
1090 (+1:+2:+3:+4:+5:+6). The new format removes all unnecessary signs
1091 by default (+1:2:3:4:5:6). Also, because of the way deltas are
1092 normalized (see documentation on ParseDateDelta), at most two signs
1093 are included. For backwards compatibility, the config variable
1094 DeltaSigns was added. If set to 1, all deltas include all 6 signs.
1095 (!) (*) Date_Init arguments
1097 The format of the Date_Init calling arguments changed. The old
1098 method
1099 Date_Init($language,$format,$tz,$convtz);
1101 is still supported , but this support will likely disappear in the
1103 future. Use the new calling format instead:
1104 Date_Init("var=val","var=val",...);
1106 NOTE: The old format is no longer supported as of version 5.32 .
1108 (*) Added weeks to ParseDateDelta.
1110 Suggested by Mike Bassman. Note that since this is a late
1111 addition, I did not change the internal format of a delta.
1112 Instead, it is added to the days field.
1113 (*) Now reads a config file.
1115 Refer to the Date_Init documentation for details.
1116 (*) Added business mode.
1118 See documentation. Suggested by Mike Bassman.
1119 New features
1121 (*) Modified how deltas are normalized and added the DeltaSigns
1122 config variable.
1123 Added %q format "YYYYMMDDHHMMSS" to UnixDate. Requested by Rob
1125 Perelman. Also added %P format "YYYYMMDDHH:MM:SS".
1126 Added a new config variable to allow you to work with multiple
1128 internal formats (with and without colons). Requested by Rob
1129 Perelman. See Date_Init documentation.
1130 Added the following formats suggested by Andreas Johansson:
1132 Sunday week 22 [in 1996] [at 12:00]
1133 22nd Sunday [in 1996] [at 12:00]
1134 Sunday 22nd week [in 1996] [at 12:00]
1135 Added a new config variable to allow you to define the first day of
1137 the week. See Date_Init documentation.
1138 Added the following formats to ParseDate for convenience (some were
1140 suggested by Mike Bassman):
1141 next/last Friday [at time]
1142 next/last week [at time]
1143 in 2 weeks [at time]
1144 2 weeks ago [at time]
1145 Friday in 2 weeks
1146 in 2 weeks on Friday
1147 Friday 2 weeks ago
1148 2 weeks ago Friday
1149 Added Date_SecsSince1970GMT, moved the %s format to %o (secs since
1151 1/1/70) and added %s format (secs since 1/1/70 GMT). Based on
1152 suggestions by Mark Osbourne. Note this introduces a minor
1153 backward incompatibility described above.
1154 Date_SetTime now works with international time separators.
1156 Added the %g format (%a, %d %b %Y %H:%M:%S %z) for an RFC 1123
1158 date. Suggested by Are Bryne.
1159 Added options to delete existing holidays and ignore global config
1161 file.
1162 Date_GetNext and Date_GetPrev now return the next/prev occurence of
1164 a time as well as a day. Suggested by Are Bryne.
1165 In approximate mode, deltas now come out completely normalized
1167 (only 1 sign). Suggested by Rob Perelman.
1168 Added Date::Manip::InitDone so initialization isn't duplicated.
1170 Added a 3rd internal format to store YYYY-MM-DD HH:MN:SS (iso
1172 8601).
1173 Added a config variable to allow you to work with 24 hour business
1175 days. Suggested by Mike Bassman.
1176 ParseDateDelta now returns "" rather than "+0:0:0:0:0:0" when there
1178 is an error.
1179 Bug fixes
1181 (*) The d:h:mn:s of ALL deltas are normalized.
1182 Huge number of code changes to clean things up.
1184 Subroutines now check to see if 4 digit years are entered.
1186 Suggested by Are Bryne.
1187 Added local($_) to all routines which use $_. Suggested by Rob
1189 Perelman.
1190 Complete rewrite of DateCalc.
1192 Fixed a bug where UnixDate %E format didn't work with single digit
1194 dates. Patch supplied by Jyrgen Nyrgaard.
1195 Fixed a bug where "today" was not converted to the correct time
1197 zone.
1198 Time zone fixes
1200 Fixed bug in Date_TimeZone where it didn't recognize +HHMN type
1201 time zones. Thanks to Are Bryne.
1202 Added WindowsNT check to Date_TimeZone to get around NT's weird
1204 date command. Thanks to Are Bryne.
1205 Fixed typo (CSD instead of CST).
1207 Fixed sign in military time zones making Date::Manip RFC 1123
1209 compliant (except that time zone information is not stored in any
1210 format)
1211 Test fixes
1213 (*) Added test suite!
1214
1216 New features
1217 Added "today at time" formats.
1218 ParseDateDelta now normalizes the delta as well as DateCalc.
1220 Added %Q format "YYYYMMDD" to UnixDate. Requested by Rob Perelman.
1222 Bug fixes
1224 Fixed another two places where a variable was declared twice using
1225 my (thanks to Ric Steinberger).
1226 Fixed a bug where fractional seconds weren't parsed correctly.
1228 Fixed a bug where "noon" and other special times were not parsed in
1230 the "which day of month" formats.
1231 Fixed a minor bug where a few matches were case sensitive.
1233 The command "date +%Z" doesn't work on SunOS machines (and perhaps
1235 others) so 5.05 is effectively broken. 5.06 released to fix this.
1236 Reported by Rob Perelman.
1237
1239 New features
1240 Changed deltas to be all positive or all negative when produced by
1241 DateCalc. Suggested by Steve Braun
1242 Added DateManipVersion routine.
1244 (*) Parses RFC 822 dates (thanks to J.B. Nicholson-Owens for
1246 suggestion).
1247 Parses ctime() date formats (suggested by Matthew R. Sheahan).
1249 Now supports times like "noon" and "midnight".
1251 Bug fixes
1253 Fixed bug introduced in 5.04 when default day set to 1. When no
1254 date given, have day default to today rather than 1. It only
1255 defaults to one if a partial date is given.
1256 Fixed bug where Date_DaysSince999 returned the wrong value (the
1258 error did not affect any other functions in Date::Manip due to the
1259 way it was called and the nature of the error). Pointed out by
1260 Jason Baker
1261 Dates with commas in them are now read properly.
1263 Fixed two places where a variable was declared twice using my
1265 (thanks to Ric Steinberger).
1266 Hopefully fixed installation problems.
1268 Got rid of the last (I think) couple of US specific strings.
1270 Fixed bug in Date_SetTime (didn't work with $hr,$min,$sec < 10).
1272 Added ModuloAddition routine and simplified DateCalc.
1274 Time zone fixes
1276 (*) Now supports time zones.
1277 (*) Added Date_ConvTZ routine for time zone support.
1279 Date_TimeZone will now also check `date '+%Z'` suggested by Aharon
1281 Schkolnik.
1282 Language fixes
1284 Added Swedish translation (thanks to Andreas Johansson
1285 The time separators are now language specific so the French can
1287 write "10h30" and the Swedes can write "10.30". Suggested by
1288 Andreas Johansson.
1289 Documentation fixes
1291 Fixed bad mistake in documentation (use Date::Manip instead of use
1292 DateManip) pointed out by tuc@valhalla.stormking.com
1293 Minor improvements to documentation.
1295 Documented the 'sort within a sort' bug.
1297 Fixed type in documentation/README pointed out by James K. Bence.

1304 Bug fixes
1306 Fixed bugs reported by J.B. Nicholson-Owens
1307 "Tue Jun 25 1996" wasn't parsed correctly (regexp was case
1308 sensitive)
1309 full day names not parsed correctly
1310 the default day in ErrorCheck should be 1, NOT currd since when
1311 currd>28, it may not be a valid date for the month
1312
1314 Bug fixes
1315 Fixed a couple of bugs in UnixDate.
1316 Declared package variables to avoid warning "Identifier XXX used
1318 only once". Thanks to Peter Bray for the suggestion.
1319
1321 New features
1322 (*) Added some internationalization (most of the routines had to be
1323 modified at least slightly)
1324 Bug fixes
