Timezone Data Versions in the Java Runtime
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.
Since the release of TZUpdater v2.0, users can now update the tzdata version in their JDK/JRE using data obtained directly from the IANA tzdata releases. Refer to the TZUpdater README for more details.

Morocco switches to permanent +01 on 2018-10-27.
Morocco switches from +00/+01 to permanent +01 effective 2018-10-27, so its clocks will not fall back on 2018-10-28 as previously scheduled. Changes to past time zone abbreviations: Change HDT to HWT/HPT for WWII-era abbreviations in Hawaii. This reverts to 2011h, as the abbreviation change in 2011i was likely inadvertent. |

in Tonga will be from the first Sunday in November through the third Sunday in January, like Fiji.
Northern Cyprus is now +03 year round, causing a split in Cyprus time zones starting 2016-10-30 at 04:00. This creates a zone Asia/Famagusta Antarctica/Casey switched from +08 to +11 on 2016-10-22. |

Asia/Gaza and Asia/Hebron end DST on 2016-10-29 at 01:00, not 2016-10-21 at 00:00. Predict that future fall
transitions will be on the last Saturday of October at 01:00, which is consistent with predicted spring
transitions on the last Saturday of March.
In Turkey, transitions in 1986-1990 were at 01:00 standard time not at 02:00, and the spring 1994 transition was on March 20, not March 27. Asia/Colombo now uses numeric time zone abbreviations like "+0530" instead of alphabetic ones like "IST" and "LKT". |

It covers Kirov Oblast, Russia, which switched from +04/+05 to +03/+04 on 1989-03-26 at 02:00, roughly a year after Europe/Volgograd made the same change. Russia and nearby locations had daylight-saving transitions on 1992-03-29 at 02:00 and 1992-09-27 at 03:00, instead of on 1992-03-28 at 23:00 and 1992-09-26 at 23:00.

Republic, Russia, which will switch from +06 to +07 on the same date and local time. Also, Asia/Sakhalin moves
from +10 to +11 on 2016-03-27 at 02:00.
As a trial of a new system that needs less information to be made up, the new zones use numeric time zone abbreviations like "+04" instead of invented abbreviations like "ASTT". Haiti will not observe DST in 2016. Palestine's spring-forward transition on 2016-03-26 is at 01:00, not 00:00. Europe/Chisinau observed DST during 1990, and switched from +04 to +03 at 1990-05-06 02:00, instead of switching from +03 to +02. 1991 abbreviations in Europe/Samara should be SAMT/SAMST, not KUYT/KUYST. |

indefinitely.
America/Whitehorse switched from UTC-9 to UTC-8 on 1967-05-28, not 1966-07-01. Also, Yukon's time zone history is documented better. The abbreviations for Hawaii-Aleutian standard and daylight times have been changed from HAST/HADT to HST/HDT, as per US Government Printing Office style. This affects only America/Adak since 1983, as America/Honolulu was already using the new style. |

Saturday in September at 00:00.
Palestine will start DST on March 28, not March 27. Also, correct the fall 2014 transition from September 26 to October 24. Adjust future predictions accordingly. The 1982 zone shift in Pacific/Easter has been corrected, fixing a 2015a regression. 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: America/Antigua, America/Cayman, Pacific/Midway, and Pacific/Saipan. Correct the 1992-2010 DST abbreviation in Volgograd from "MSK" to "MSD". |

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). |

1.4.8 | 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. |

1.4.7 | 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. |

1.4.6 | 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. |

1.4.5 | 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. |
