Timezone Data Versions in the JRE Software

   
By the Java SE Platform Support Team, Oct 2014  

This table shows which version of the Timezone data is included in the different releases of the Java Development Kit (JDK) software and the TZUpdater tool. Further information about the contents of the timezone data releases is contained in the related request for enhancement (RFE) for that release. Where a major timezone change has been included in a timezone data release, this is described in the last column.

Latest TZdata release can be found from IANA TZdata page.

If you want to be informed about timezone data updates in the Java SE platform and the TZUpdater tool as soon as they happen, subscribe to the timezone data version RSS feed.

tzdata2014i
 
 
 
 
Pacific/Fiji will observe DST from 2014-11-02 02:00 to 2015-01-18 03:00.
A new Zone Pacific/Bougainville, for the part of Papua New Guinea that plans to switch from UTC+10 to UTC+11 on 2014-12-28 at 02:00.
Since Belarus is not changing its clocks even though Moscow is, the time zone abbreviation in Europe/Minsk is changing from FET to its more-traditional value MSK on 2014-10-26 at 01:00.
The new abbreviation IDT stands for the pre-1976 use of UT+8 in Indochina, to distinguish it better from ICT (UT+7).
tzdata2014h
 
 
 
 
America/Jamaica's 1974 spring-forward transition was Jan. 6, not Apr. 28.
Asia/Novokuznetsk switched from LMT (not "NMT") on 1924-05-01, not 1920-01-06.
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/Blantyre, Africa/Bujumbura, Africa/Gaborone, Africa/Harare, Africa/Kigali, Africa/Lubumbashi, Africa/Lusaka, Africa/Maseru, and Africa/Mbabane.
tzdata2014g
 
 
 
 
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.
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.
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.
Asia/Dhaka ended DST on 2009-12-31 at 24:00, not 23:59.
tzdata2014f
 
 
 
 
Russia will subtract an hour from most of its time zones on 2014-10-26 at 02:00 local time. 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).
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.
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.
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.
tzdata2014e
 
 
 
 
Egypt's 2014 Ramadan-based transitions are June 26 and July 31 at 24:00. Guess that from 2015 on Egypt will temporarily switch to standard time at 24:00 the last Thursday before Ramadan, and back to DST at 00:00 the first Friday after Ramadan.
Similarly, Morocco's are June 28 at 03:00 and August 2 at 02:00. Guess that from 2015 on Morocco will temporarily switch to standard time at 03:00 the last Saturday before Ramadan, and back to DST at 02:00 the first Saturday after Ramadan.
The abbreviation "MSM" (Moscow Midsummer Time) is now used instead of "MSD" for Moscow's double daylight time in summer 1921. Also, a typo "VLASST" has been repaired to be "VLAST" for Vladivostok summer time in 1991.
