[tz-announce] 2016g release of tz code and data available
by Paul Eggert Sept. 28, 2016

Sept. 28, 2016

The 2016g 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 to future time stamps Turkey switched from EET/EEST (+02/+03) to permanent +03, effective 2016-09-07. (Thanks to Burak AYDIN.) Use "+03" rather than an invented abbreviation for the new time. New leap second 2016-12-31 23:59:60 UTC as per IERS Bulletin C 52. (Thanks to Tim Parenti.) Changes to past time stamps For America/Los_Angeles, spring-forward transition times have been corrected from 02:00 to 02:01 in 1948, and from 02:00 to 01:00 in 1950-1966. For zones using Soviet time on 1919-07-01, transitions to UT-based time were at 00:00 UT, not at 02:00 local time. The affected zones are Europe/Kirov, Europe/Moscow, Europe/Samara, and Europe/Ulyanovsk. (Thanks to Alexander Belopolsky.) Changes to past and future time zone abbreviations The Factory zone now uses the time zone abbreviation -00 instead of a long English-language string, as -00 is now the normal way to represent an undefined time zone. Several zones in Antarctica and the former Soviet Union, along with zones intended for ships at sea that cannot use POSIX TZ strings, now use numeric time zone abbreviations instead of invented or obsolete alphanumeric abbreviations. The affected zones are Antarctica/Casey, Antarctica/Davis, Antarctica/DumontDUrville, Antarctica/Mawson, Antarctica/Rothera, Antarctica/Syowa, Antarctica/Troll, Antarctica/Vostok, Asia/Anadyr, Asia/Ashgabat, Asia/Baku, Asia/Bishkek, Asia/Chita, Asia/Dushanbe, Asia/Irkutsk, Asia/Kamchatka, Asia/Khandyga, Asia/Krasnoyarsk, Asia/Magadan, Asia/Omsk, Asia/Sakhalin, Asia/Samarkand, Asia/Srednekolymsk, Asia/Tashkent, Asia/Tbilisi, Asia/Ust-Nera, Asia/Vladivostok, Asia/Yakutsk, Asia/Yekaterinburg, Asia/Yerevan, Etc/GMT-14, Etc/GMT-13, Etc/GMT-12, Etc/GMT-11, Etc/GMT-10, Etc/GMT-9, Etc/GMT-8, Etc/GMT-7, Etc/GMT-6, Etc/GMT-5, Etc/GMT-4, Etc/GMT-3, Etc/GMT-2, Etc/GMT-1, Etc/GMT+1, Etc/GMT+2, Etc/GMT+3, Etc/GMT+4, Etc/GMT+5, Etc/GMT+6, Etc/GMT+7, Etc/GMT+8, Etc/GMT+9, Etc/GMT+10, Etc/GMT+11, Etc/GMT+12, Europe/Kaliningrad, Europe/Minsk, Europe/Samara, Europe/Volgograd, and Indian/Kerguelen. For Europe/Moscow the invented abbreviation MSM was replaced by +05, whereas MSK and MSD were kept as they are not our invention and are widely used. Changes to zone names Rename Asia/Rangoon to Asia/Yangon, with a backward compatibility link. (Thanks to David Massoud.) Changes to code zic no longer generates binary files containing POSIX TZ-like strings that disagree with the local time type after the last explicit transition in the data. This fixes a bug with Africa/Casablanca and Africa/El_Aaiun in some year-2037 time stamps on the reference platform. (Thanks to Alexander Belopolsky for reporting the bug and suggesting a way forward.) If the installed localtime and/or posixrules files are symbolic links, zic now keeps them symbolic links when updating them, for compatibility with platforms like OpenSUSE where other programs configure these files as symlinks. zic now avoids hard linking to symbolic links, avoids some unnecessary mkdir and stat system calls, and uses shorter file names internally. zdump has a new -i option to generate transitions in a more-compact but still human-readable format. This option is experimental, and the output format may change in future versions. (Thanks to Jon Skeet for suggesting that an option was needed, and thanks to Tim Parenti and Chris Rovick for further comments.) Changes to build procedure An experimental distribution format is available, in addition to the traditional format which will continue to be distributed. The new format is a tarball tzdb-VERSION.tar.lz with signature file tzdb-VERSION.tar.lz.asc. It unpacks to a top-level directory tzdb-VERSION containing the code and data of the traditional two-tarball format, along with extra data that may be useful. (Thanks to Antonio Diaz Diaz, Oscar van Vlijmen, and many others for comments about the experimental format.) The release version number is now more accurate in the usual case where releases are built from a Git repository. For example, if 23 commits and some working-file changes have been made since release 2016g, the version number is now something like '2016g-23-g50556e3-dirty' instead of the misleading '2016g'. Official releases uses the same version number format as before, e.g., '2016g'. To support the more-accurate version number, its specification has moved from a line in the Makefile to a new source file 'version'. The experimental distribution contains a file to2050.tzs that contains what should be the output of 'zdump -i -c 2050' on primary zones. If this file is available, 'make check' now checks that zdump generates this output. 'make check_web' now works on Fedora-like distributions. Changes to documentation and commentary tzfile.5 now documents the new restriction on POSIX TZ-like strings that is now implemented by zic. Comments now cite URLs for some 1917-1921 Russian DST decrees. (Thanks to Alexander Belopolsky.) tz-link.htm mentions JuliaTime (thanks to Curtis Vogt) and Time4J (thanks to Meno Hochschild) and ThreeTen-Extra, and its description of Java 8 has been brought up to date (thanks to Stephen Colebourne). Its description of local time on Mars has been updated to match current practice, and URLs have been updated and some obsolete ones removed.

Istanbul fix for 1986-2006
by Kıvanç Yazan Sept. 25, 2016

Sept. 25, 2016

Hi! I've been looking at DST rules of Turkey, and I run into a few issues. 1) For 1986-2006, DST started at 01:00 local and ended at 02:00 local, with no exceptions. 2) 1994's lastSun was overridden with Mar 20, which was not reflected. Links in comments were inaccessible and some were not official. Here are official papers: http://www.resmigazete.gov.tr/arsiv/19032.pdf -- page 2 for 1986 http://www.resmigazete.gov.tr/arsiv/19400.pdf -- page 4 for 1987 http://www.resmigazete.gov.tr/arsiv/19752.pdf -- page 15 for 1988 http://www.resmigazete.gov.tr/arsiv/20102.pdf -- page 6 for 1989 http://www.resmigazete.gov.tr/arsiv/20464.pdf -- page 1 for 1990 - 1992 http://www.resmigazete.gov.tr/arsiv/21531.pdf -- page 15 for 1993 - 1995 http://www.resmigazete.gov.tr/arsiv/21879.pdf -- page 1 for overriding 1994 http://www.resmigazete.gov.tr/arsiv/22588.pdf -- page 1 for 1996, 1997 http://www.resmigazete.gov.tr/arsiv/23286.pdf -- page 10 for 1998 - 2000 http://www.resmigazete.gov.tr/eskiler/2001/03/20010324.htm#2 -- for 2001 http://www.resmigazete.gov.tr/eskiler/2002/03/20020316.htm#2 -- for 2002 - 2006 Sincerely, Kivanc Yazan

Backward compatibility of tzfile?
by Deborah Goldsmith Sept. 21, 2016

Sept. 21, 2016

Hi, Is the intent that successive versions of the tzfile format will be compatible with older implementations of localtime.c, date.c, etc.? Obviously they wouldn’t be able to take advantage of any new information, but is the idea they’ll still be able to read it? I wasn’t able to find anything in the man pages about this. Thanks, Debbie
