Several minor patches
by Tim Parenti Aug. 10, 2014

Aug. 10, 2014

Attached are another round of patches, relative to 62060419e3b81752ee5c1bda546c0ff87d66ea3e. 0001 expands a bit commentary in tz-art.htm. 0002 adjusts some Rule lines, since zic has been able to handle 24:00. This changes timestamps for one minute in Asia/Dhaka at the end of 2009-12-31 to better match the contemporaneous commentary. The rest are minor, with 0003 fixing up spacing in the UNTIL fields of Zone and Zone continuation lines, and with 0004 and 0005 fixing up commentary for consistency. These can be compared at https://github.com/timparenti/tz-experimental/compare/eggert:master...timpa… -- Tim Parenti

Re: [tz] Correct time in Russia before 1927 or so
by Vladimir Karpinsky Aug. 7, 2014

Aug. 7, 2014

It looks like data taken from Milne 1899 are not correct enough for 1919. Data by Byalokoz E.L. are slightly different. I think they are reliable, because in 1919 he was a president of the Russian Committee of Standard Time. The difference may result from the new standard that was accepted in Russia on Jul 3, 1916. > From: Paul Eggert <eggert(a)cs.ucla.edu> > Date: Tue, 8 Jul 2014 19:23:04 -0700 > Subject: [PATCH] Correct time in Russia before 1927 or so. > > (Thanks to Vladimir Karpinsky for the Moscow corrections.) > Other corrections are taken from Milne 1899. > * asia (Asia/Tbilisi): Change LMT from 2:59:16 to 2:59:06. > (Asia/Tashkent): Change LMT from 4:37:12 to 4:37:11. > * europe (Europe/Helsinki): Change LMT from 1:39:52 to 1:39:49. > (Europe/Riga): Change LMT from 1:36:24 to 1:36:28. > (Europe/Moscow): Change LMT from 2:30:20 to 2:30:17. > Change 1916/9 time from 2:30:48 to 2:31:19. > (Asia/Yekaterinburg): Change LMT from 4:02:24 to 4:02:33. > (Asia/Irkutsk): Change LMT from 6:57:20 to 6:57:15. > (Asia/Vladivostok): Change LMT from 8:47:44 to 8:47:34. > * zone.tab (Europe/Moscow): Use Kilometer 0 point. > * NEWS: Document this.

2014f and Russia
by Deborah Goldsmith Aug. 6, 2014

Aug. 6, 2014

Given the long lead time for deployment of TZ data in some cases, may I suggest that we expedite the release of the changes for Russia in 2014f, and defer any contentious changes to a subsequent release? Thank you, Deborah

[tz-announce] 2014f release of tz code and data available
by Paul Eggert Aug. 6, 2014

Aug. 6, 2014

The 2014f 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 Russia will subtract an hour from most of its time zones on 2014-10-26 at 02:00 local time. (Thanks to Alexander Krivenyshev.) There are a few exceptions: Magadan Oblast (Asia/Magadan) and Zabaykalsky Krai are subtracting two hours; conversely, Chukotka Autonomous Okrug (Asia/Anadyr), Kamchatka Krai (Asia/Kamchatka), Kemerovo Oblast (Asia/Novokuznetsk), and the Samara Oblast and the Udmurt Republic (Europe/Samara) are not changing their clocks. The changed zones are Europe/Kaliningrad, Europe/Moscow, Europe/Simferopol, Europe/Volgograd, Asia/Yekaterinburg, Asia/Omsk, Asia/Novosibirsk, Asia/Krasnoyarsk, Asia/Irkutsk, Asia/Yakutsk, Asia/Vladivostok, Asia/Khandyga, Asia/Sakhalin, and Asia/Ust-Nera; Asia/Magadan will have two hours subtracted; and Asia/Novokuznetsk's time zone abbreviation is affected, but not its UTC offset. Two zones are added: Asia/Chita (split from Asia/Yakutsk, and also with two hours subtracted) and Asia/Srednekolymsk (split from Asia/Magadan, but with only one hour subtracted). (Thanks to Tim Parenti for much of the above.) Changes affecting time zone abbreviations Australian eastern time zone abbreviations are now AEST/AEDT not EST, and similarly for the other Australian zones. That is, for eastern standard and daylight saving time the abbreviations are AEST and AEDT instead of the former EST for both; similarly, ACST/ACDT, ACWST/ACWDT, and AWST/AWDT are now used instead of the former CST, CWST, and WST. This change does not affect UTC offsets, only time zone abbreviations. (Thanks to Rich Tibbett and many others.) Asia/Novokuznetsk shifts from NOVT to KRAT (remaining on UTC+7) effective 2014-10-26 at 02:00 local time. The time zone abbreviation for Xinjiang Time (observed in Ürümqi) has been changed from URUT to XJT. (Thanks to Luther Ma.) Prefer MSK/MSD for Moscow time in Russia, even in other cities. Similarly, prefer EET/EEST for eastern European time in Russia. Change time zone abbreviations in (western) Samoa to use "ST" and "DT" suffixes, as this is more likely to match common practice. Prefix "W" to (western) Samoa time when its standard-time offset disagrees with that of American Samoa. America/Metlakatla now uses PST, not MeST, to abbreviate its time zone. Time zone abbreviations have been updated for Japan's two time zones used 1896-1937. JWST now stands for Western Standard Time, and JCST for Central Standard Time (formerly this was CJT). These abbreviations are now used for time in Korea, Taiwan, and Sakhalin while controlled by Japan. Changes affecting past time stamps China's five zones have been simplified to two, since the post-1970 differences in the other three seem to have been imaginary. The zones Asia/Harbin, Asia/Chongqing, and Asia/Kashgar have been removed; backwards-compatibility links still work, albeit with different behaviors for time stamps before May 1980. Asia/Urumqi's 1980 transition to UTC+8 has been removed, so that it is now at UTC+6 and not UTC+8. (Thanks to Luther Ma and to Alois Treindl; Treindl sent helpful translations of two papers by Guo Qingsheng.) Some zones have been turned into links, when they differed from existing zones only for older UTC offsets where the data were likely invented. These changes affect UTC offsets in pre-1970 time stamps only. This is similar to the change in release 2013e, except this time for western Africa. The affected zones are: Africa/Bamako, Africa/Banjul, Africa/Conakry, Africa/Dakar, Africa/Freetown, Africa/Lome, Africa/Nouakchott, Africa/Ouagadougou, Africa/Sao_Tome, and Atlantic/St_Helena. This also affects the backwards-compatibility link Africa/Timbuktu. (Thanks to Alan Barrett, Stephen Colebourne, Tim Parenti, and David Patte for reporting problems in earlier versions of this change.) Asia/Shanghai's pre-standard-time UT offset has been changed from 8:05:57 to 8:05:43, the location of Xujiahui Observatory. Its transition to standard time has been changed from 1928 to 1901. Asia/Taipei switched to JWST on 1896-01-01, then to JST on 1937-10-01, then to CST on 1945-09-21 at 01:00, and did not observe DST in 1945. In 1946 it observed DST from 05-15 through 09-30; in 1947 from 04-15 through 10-31; and in 1979 from 07-01 through 09-30. (Thanks to Yu-Cheng Chuang.) Asia/Riyadh's transition to standard time is now 1947-03-14, not 1950. Europe/Helsinki's 1942 fall-back transition was 10-04 at 01:00, not 10-03 at 00:00. (Thanks to Konstantin Hyppönen.) Pacific/Pago_Pago has been changed from UTC-11:30 to UTC-11 for the period from 1911 to 1950. Pacific/Chatham has been changed to New Zealand standard time plus 45 minutes for the period before 1957, reflecting a 1956 remark in the New Zealand parliament. Europe/Budapest has several pre-1946 corrections: in 1918 the transition out of DST was on 09-16, not 09-29; in 1919 it was on 11-24, not 09-15; in 1945 it was on 11-01, not 11-03; in 1941 the transition to DST was 04-08 not 04-06 at 02:00; and there was no DST in 1920. Africa/Accra is now assumed to have observed DST from 1920 through 1935. Time in Russia before 1927 or so has been corrected by a few seconds in the following zones: Europe/Moscow, Asia/Irkutsk, Asia/Tbilisi, Asia/Tashkent, Asia/Vladivostok, Asia/Yekaterinburg, Europe/Helsinki, and Europe/Riga. Also, Moscow's location has been changed to its Kilometer 0 point. (Thanks to Vladimir Karpinsky for the Moscow changes.) Changes affecting data format A new file 'zone1970.tab' supersedes 'zone.tab' in the installed data. The new file's extended format allows multiple country codes per zone. The older file is still installed but is deprecated; its format is not changing and it will still be distributed for a while, but new applications should use the new file. The new file format simplifies maintenance of obscure locations. To test this, it adds coverage for the Crozet Islands and the Scattered Islands. (Thanks to Tobias Conradi and Antoine Leca.) The file 'iso3166.tab' is planned to switch from ASCII to UTF-8. It is still ASCII now, but commentary about the switch has been added. The new file 'zone1970.tab' already uses UTF-8. Changes affecting code 'localtime', 'mktime', etc. now use much less stack space if ALL_STATE is defined. (Thanks to Elliott Hughes for reporting the problem.) 'zic' no longer mishandles input when ignoring case in locales that are not compatible with English, e.g., unibyte Turkish locales when compiled with HAVE_GETTEXT. Error diagnostics of 'zic' and 'yearistype' have been reworded so that they no longer use ASCII '-' as if it were a dash. 'zic' now rejects output file names that contain '.' or '..' components. (Thanks to Tim Parenti for reporting the problem.) 'zic -v' now warns about output file names that do not follow POSIX rules, or that contain a digit or '.'. (Thanks to Arthur David Olson for starting the ball rolling on this.) Some lint has been removed when using GCC_DEBUG_FLAGS with GCC 4.9.0. Changes affecting build procedure 'zic' no longer links in localtime.o and asctime.o, as they're not needed. (Thanks to John Cochran.) Changes affecting documentation and commentary The 'Theory' file documents legacy names, the longstanding exceptions to the POSIX-inspired file name rules. The 'zic' documentation clarifies the role of time types when interpreting dates. (Thanks to Arthur David Olson.) Documentation and commentary now prefer UTF-8 to US-ASCII, allowing the use of proper accents in foreign words and names. Code and data have not changed because of this. (Thanks to Garrett Wollman, Ian Abbott, and Guy Harris for helping to debug this.) Non-HTML documentation and commentary now use plain-text URLs instead of HTML insertions, and are more consistent about bracketing URLs when they are not already surrounded by white space. (Thanks to suggestions by Steffen Nurpmeso.) There is new commentary about Xujiahui Observatory, the five timezone project in China from 1918 to 1949, timekeeping in Japanese-occupied Shanghai, and Tibet Time in the 1950s. The sharp-eyed can spot the warlord Jin Shuren in the data. Commentary about the coverage of each Russian zone has been standardized. (Thanks to Tim Parenti). There is new commentary about contemporary timekeeping in Ethiopia. Obsolete comments about a 2007 proposal for DST in Kuwait has been removed. There is new commentary about time in Poland in 1919. Proper credit has been given to DST inventor George Vernon Hudson. Commentary about time in Metlakatla, AK and Resolute, NU has been improved, with a new source for the former. In zone.tab, Pacific/Easter no longer mentions Salas y Gómez, as it is uninhabited. Commentary about permanent Antarctic bases has been updated. Several typos have been corrected. (Thanks to Tim Parenti for contributing some of these fixes.) tz-link.htm now mentions the JavaScript libraries Moment Timezone, TimezoneJS.Date, Walltime-js, and Timezone. (Thanks to a heads-up from Matt Johnson.) Also, it mentions the Go 'latlong' package. (Thanks to a heads-up from Dirkjan Ochtman.) The files usno1988, usno1989, usno1989a, usno1995, usno1997, and usno1998 have been removed. These obsolescent US Naval Observatory entries were no longer helpful for maintenance.

Large scale changes proposed in 2014f
by Stephen Colebourne Aug. 5, 2014

I believe that the changes currently proposed are far far too widespread and damaging. I have taken the latest in the GitHub repo and expanded them out into actual resolved results. The differences between 2014e and 2014f-proposed can be seen here: https://github.com/jodastephen/tzdiff/commit/c812da9e12bd6f8aa52fa2dd758e23… (other version differences available here: https://github.com/jodastephen/tzdiff/commits/proposed-2014f) As can be seen from the first link, the changes proposed are very widespread. they include - Africa/Accra gains DST between 1920 and 1935 - Africa/Freetown loses its entire history of DST - Africa/Kampala has very different DST history - Africa/Dar_es_Salaam has entirely different history before 1961 - Africa/Djibouti gains history before 1960 - Africa/Addis_Ababa has completely different history before 1960 - Africa/Asmara has completely different history before 1960 - Africa/Conakry loses history before 1960 - Africa/Banjul loses history before 1964 - Africa/Maseru gains DST history - Africa/Mbabane gains DST history - Africa/Mogadishu gains completely different DST history and many others with more minor changes. I'd also note that Ho_Chi_Minh, Kashgar, Saigon, Vientiane and Phnom_Penh lose their entire history The changes to Asia/Qatar and Asia/Kuwait look suspect. Asia/Urumqi loses its entire history. Indian/Antananarivo, Comoro and Mayotte get entirely different DST history. Pacific/Midway, Pago_Pago, Saipan, Samoa get entirely different DST history. The above is an attempt to summarise some but not all of the changes. I am far from convinced that the scale of the proposed changes (far bigger than even 2013e) have been anywhere near justified. Is there consensus on the list that all of these changes are better than what went before?
