proposed time zone package changes (Samoa, Factory, et al.)
by Arthur David Olson 28 Aug '19

28 Aug '19

Below find proposed time zone package changes; the executive summary: * Makefile Change LOCALTIME default from "Factory" to "GMT"; do not compile "factory" file (but keep it in the distribution). * Theory Remove reference to "Factory" zone. * australasia Change end of DST in Samoa in 2011 from 2011-04-03 0:00 to 2011-04-03 1:00 (thanks to Raymond Hughes for a reference). * localtime.c Initialize ttinfo structures filled by tzparse (thanks to Ravindra for reporting a valgrind warning). * zic.c Fix generation of POSIX strings for zones with rules using "weekday<=n" forms of dates (thanks to Lei Liu for finding the problem). Also, limit output for non-POSIX-specificable zones defined to follow the same rules every year. (Note that no zones of either of the above types appear in the distribution; these changes cater to add-on zones). If no problems are found, 2010n will appear on 2010-10-25. --ado diff -r -c old/Makefile new/Makefile *** old/Makefile Mon Sep 27 09:24:25 2010 --- new/Makefile Tue Oct 12 12:36:50 2010 *************** *** 1,5 **** # <pre> ! # @(#)Makefile 8.8 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)Makefile 8.9 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 12,18 **** # make zonenames # to get a list of the values you can use for LOCALTIME. !

zic changes (2/2)
by Arthur David Olson 09 Mar '16

09 Mar '16

And now, the update. These changes arrange things so that binary files include "transition" entries for minimum time values; these entries eliminate localtime guesswork in handling low-valued time stamps. The bad news: binary files grow slightly as a result of these changes. The good news: there are no changes in the output of "zdump -v" applied to before-and-after versions of all the binary files generated by a "make install." Changes are attached and appear in mangled form below; these are relative to the github version of zic.c after the rollback in the earlier message today. @dashdashado 1.2 2805 lines 1.4 2813 lines *** /tmp/,azic.c 2014-05-01 01:51:36.998933800 -0400 --- /tmp/,bzic.c 2014-05-01 01:51:37.092534000 -0400 *************** *** 1480,1493 **** fromi = 0; while (fromi < timecnt && attypes[fromi].at < min_time) ++fromi; - if (isdsts[0] == 0) - while (fromi < timecnt && attypes[fromi].type == 0) - ++fromi; /* handled by default rule */ for ( ; fromi < timecnt; ++fromi) { ! if (toi != 0 && ((attypes[fromi].at + gmtoffs[attypes[toi - 1].type]) <= !

Adding Asia/Beijing timezone into the database
by Daoming Qiu 06 Dec '14

06 Dec '14

"Beijing Time" is the standard time used for China region, so it is very strange that tzdatabase doesn't have timezone called Asia/Beijing. Strongly suggest to add "Asia/Beijing" zone into the database, and its information is very similar with "Asia/Shanghai".

[tz-announce] 2014g release of tz code and data available
by Paul Eggert 11 Nov '14

11 Nov '14

The 2014g release of the tz code and data is available. It reflects the following changes, which were either circulated on the tz mailing list or are relatively minor technical or administrative changes: Changes affecting future time stamps Turks & Caicos is switching from US eastern time to UTC-4 year-round, modeled as a switch from EST/EDT to AST on 2014-11-02 at 02:00. Changes affecting past time stamps Time in Russia or the USSR before 1926 or so has been corrected by a few seconds in the following zones: Asia/Irkutsk, Asia/Krasnoyarsk, Asia/Omsk, Asia/Samarkand, Asia/Tbilisi, Asia/Vladivostok, Asia/Yakutsk, Europe/Riga, Europe/Samara. For Asia/Yekaterinburg the correction is a few minutes. (Thanks to Vladimir Karpinsky.) The Portuguese decree of 1911-05-26 took effect on 1912-01-01. This affects 1911 time stamps in Africa/Bissau, Africa/Luanda, Atlantic/Azores, and Atlantic/Madeira. Also, Lisbon's pre-1912 GMT offset was -0:36:45 (rounded from -0:36:44.68), not -0:36:32. (Thanks to Stephen Colebourne for pointing to the decree.) Asia/Dhaka ended DST on 2009-12-31 at 24:00, not 23:59. A new file 'backzone' contains data which may appeal to connoisseurs of old time stamps, although it is out of scope for the tz database, is often poorly sourced, and contains some data that is known to be incorrect. The new file is not recommended for ordinary use and its entries are not installed by default. (Thanks to Lester Caine for the high-quality Jersey, Guernsey, and Isle of Man entries.) Some more zones have been turned into links, when they differed from existing zones only for older time stamps. As usual, these changes affect UTC offsets in pre-1970 time stamps only. Their old contents have been moved to the 'backzone' file. The affected zones are: Africa/Bangui, Africa/Brazzaville, Africa/Douala, Africa/Kinshasa, Africa/Libreville, Africa/Luanda, Africa/Malabo, Africa/Niamey, and Africa/Porto-Novo. Changes affecting code Unless NETBSD_INSPIRED is defined to 0, the tz library now supplies functions for creating and using objects that represent time zones. The new functions are tzalloc, tzfree, localtime_rz, mktime_z, and (if STD_INSPIRED is also defined) posix2time_z and time2posix_z. They are intended for performance: for example, localtime_rz (unlike localtime_r) is trivially thread-safe without locking. (Thanks to Christos Zoulas for proposing NetBSD-inspired functions, and to Alan Barrett and Jonathan Lennox for helping to debug the change.) zdump now builds with the tz library unless USE_LTZ is defined to 0, This lets zdump use tz features even if the system library lacks them. To build zdump with the system library, use 'make CFLAGS=-DUSE_LTZ=0 TZDOBJS=zdump.o CHECK_TIME_T_ALTERNATIVES='. zdump now uses localtime_rz if available, as it's significantly faster, and it can help zdump better diagnose invalid time zone names. Define HAVE_LOCALTIME_RZ to 0 to suppress this. HAVE_LOCALTIME_RZ defaults to 1 if NETBSD_INSPIRED && USE_LTZ. When localtime_rz is not available, zdump now uses localtime_r and tzset if available, as this is a bit cleaner and faster than plain localtime. Compile with -DHAVE_LOCALTIME_R=0 and/or -DHAVE_TZSET=0 if your system lacks these two functions. If THREAD_SAFE is defined to 1, the tz library is now thread-safe. Although not needed for tz's own applications, which are single-threaded, this supports POSIX better if the tz library is used in multithreaded apps. Some crashes have been fixed when zdump or the tz library is given invalid or outlandish input. The tz library no longer mishandles leap seconds on platforms with unsigned time_t in time zones that lack ordinary transitions after 1970. The tz code now attempts to infer TM_GMTOFF and TM_ZONE if not already defined, to make it easier to configure on common platforms. Define NO_TM_GMTOFF and NO_TM_ZONE to suppress this. Unless the new macro UNINIT_TRAP is defined to 1, the tz code now assumes that reading uninitialized memory yields garbage values but does not cause other problems such as traps. If TM_GMTOFF is defined and UNINIT_TRAP is 0, mktime is now more likely to guess right for ambiguous time stamps near transitions where tm_isdst does not change. If HAVE_STRFTIME_L is defined to 1, the tz library now defines strftime_l for compatibility with recent versions of POSIX. Only the C locale is supported, though. HAVE_STRFTIME_L defaults to 1 on recent POSIX versions, and to 0 otherwise. tzselect -c now uses a hybrid distance measure that works better in Africa. (Thanks to Alan Barrett for noting the problem.) The C source code now ports to NetBSD when GCC_DEBUG_FLAGS is used, or when time_tz is defined. When HAVE_UTMPX_H is set the 'date' command now builds on systems whose <utmpx.h> file does not define WTMPX_FILE, and when setting the date it updates the wtmpx file if _PATH_WTMPX is defined. This affects GNU/Linux and similar systems. For easier maintenance later, some C code has been simplified, some lint has been removed, and the code has been tweaked so that plain 'make' is more likely to work. The C type 'bool' is now used for boolean values, instead of 'int'. The long-obsolete LOCALE_HOME code has been removed. The long-obsolete 'gtime' function has been removed. Changes affecting build procedure 'zdump' no longer links in ialloc.o, as it's not needed. 'make check_time_t_alternatives' no longer assumes GNU diff. Changes affecting distribution tarballs The files checktab.awk and zoneinfo2tdf.pl are now distributed in the tzdata tarball instead of the tzcode tarball, since they help maintain the data. The NEWS and Theory files are now also distributed in the tzdata tarball, as they're relevant for data. (Thanks to Alan Barrett for pointing this out.) Also, the leapseconds.awk file is no longer distributed in the tzcode tarball, since it belongs in the tzdata tarball (where 2014f inadvertently also distributed it). Changes affecting documentation and commentary A new file CONTRIBUTING is distributed. (Thanks to Tim Parenti for suggesting a CONTRIBUTING file, and to Tony Finch and Walter Harms for debugging it.) The man pages have been updated to use function prototypes, to document thread-safe variants like localtime_r, and to document the NetBSD-inspired functions tzalloc, tzfree, localtime_rz, and mktime_z. The fields in Link lines have been renamed to be more descriptive and more like the parameters of 'ln'. LINK-FROM has become TARGET, and LINK-TO has become LINK-NAME. tz-link.htm mentions the IETF's tzdist working group; Windows Runtime etc. (thanks to Matt Johnson); and HP-UX's tztab. Some broken URLs have been fixed in the commentary. (Thanks to Lester Caine.) Commentary about Philippines DST has been updated, and commentary on pre-1970 time in India has been added.
