tzdata/tzcode-native: update to 2018i

2019-01-03T12:35:54+00:00

2018i: Briefly: São Tomé and Príncipe switches from +01 to +00 on 2019-01-01. Changes to future timestamps Due to a change in government, São Tomé and Príncipe switches back from +01 to +00 on 2019-01-01 at 02:00. (Thanks to Vadim Nasardinov and Michael Deckers.) 2018h: Briefly: Qyzylorda, Kazakhstan moved from +06 to +05 on 2018-12-21. New zone Asia/Qostanay because Qostanay, Kazakhstan didn't move. Metlakatla, Alaska observes PST this winter only. Guess Morocco will continue to adjust clocks around Ramadan. Add predictions for Iran from 2038 through 2090. Changes to future timestamps Guess that Morocco will continue to fall back just before and spring forward just after Ramadan, the practice since 2012. (Thanks to Maamar Abdelkader.) This means Morocco will observe negative DST during Ramadan in main and vanguard formats, and in rearguard format it stays in the +00 timezone and observes ordinary DST in all months other than Ramadan. As before, extend this guesswork to the year 2037. As a consequence, Morocco is scheduled to observe three DST transitions in some Gregorian years (e.g., 2033) due to the mismatch between the Gregorian and Islamic calendars. The table of exact transitions for Iranian DST has been extended. It formerly cut off before the year 2038 in a nod to 32-bit time_t. It now cuts off before 2091 as there is doubt about how the Persian calendar will treat 2091. This change predicts DST transitions in 2038-9, 2042-3, and 2046-7 to occur one day later than previously predicted. As before, post-cutoff transitions are approximated. Changes to past and future timestamps Qyzylorda (aka Kyzylorda) oblast in Kazakhstan moved from +06 to +05 on 2018-12-21. This is a zone split as Qostanay (aka Kostanay) did not switch, so create a zone Asia/Qostanay. Metlakatla moved from Alaska to Pacific standard time on 2018-11-04. It did not change clocks that day and remains on -08 this winter. (Thanks to Ryan Stanley.) It will revert to the usual Alaska rules next spring, so this change affects only timestamps from 2018-11-04 through 2019-03-10. Change to past timestamps Kwajalein's 1993-08-20 transition from -12 to +12 was at 24:00, not 00:00. I transcribed the time incorrectly from Shanks. (Thanks to Phake Nick.) Nauru's 1979 transition was on 02-10 at 02:00, not 05-01 at 00:00. (Thanks to Phake Nick.) Guam observed DST irregularly from 1959 through 1977. (Thanks to Phake Nick.) Hong Kong observed DST in 1941 starting 06-15 (not 04-01), then on 10-01 changed standard time to +08:30 (not +08). Its transition back to +08 after WWII was on 1945-09-15, not the previous day. Its 1904-10-30 change took effect at 01:00 +08 (not 00:00 LMT). (Thanks to Phake Nick, Steve Allen, and Joseph Myers.) Also, its 1952 fallback was on 11-02 (not 10-25). This release contains many changes to timestamps before 1946 due to Japanese possession or occupation of Pacific/Chuuk, Pacific/Guam, Pacific/Kosrae, Pacific/Kwajalein, Pacific/Majuro, Pacific/Nauru, Pacific/Palau, and Pacific/Pohnpei. (Thanks to Phake Nick.) Assume that the Spanish East Indies was like the Philippines and observed American time until the end of 1844. This affects Pacific/Chuuk, Pacific/Kosrae, Pacific/Palau, and Pacific/Pohnpei. Changes to past tm_isdst flags For the recent Morocco change, the tm_isdst flag should be 1 from 2018-10-27 00:00 to 2018-10-28 03:00. (Thanks to Michael Deckers.) Give a URL to the official decree.

tzdata: update to 2018g

2018-11-07T23:08:54+00:00

Changes to code When generating TZif files with leap seconds, zic no longer uses a format that trips up older 32-bit clients, fixing a bug introduced in 2018f. (Reported by Daniel Fischer.) Also, the zic workaround for QTBUG-53071 now also works for TZif files with leap seconds. The translator to rearguard format now rewrites the line "Rule Japan 1948 1951 - Sep Sat>=8 25:00 0 S" to "Rule Japan 1948 1951 - Sep Sun>=9 1:00 0 S". This caters to zic before 2007 and to Oracle TZUpdater 2.2.0 and earlier. (Reported by Christos Zoulas.) 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. Changes to documentation tzfile.5 has new sections on interoperability issues. (From OE-Core rev: 32e5dd919a61b1c245fb6a867d0ea4a71d394aca) Signed-off-by: Armin Kuster Signed-off-by: Richard Purdie

tzdata: update to 2018f

2018-10-29T17:37:26+00:00

Briefly: Volgograd moves from +03 to +04 on 2018-10-28. Fiji ends DST 2019-01-13, not 2019-01-20. Most of Chile changes DST dates, effective 2019-04-06. Changes to future timestamps Volgograd moves from +03 to +04 on 2018-10-28 at 02:00. (Thanks to Alexander Fetisov and Stepan Golosunov.) Fiji ends DST 2019-01-13 instead of the 2019-01-20 previously predicted. (Thanks to Raymond Kumar.) Adjust future predictions accordingly. Most of Chile will end DST on the first Saturday in April at 24:00 mainland time, and resume DST on the first Saturday in September at 24:00 mainland time. The changes are effective from 2019-04-06, and do not affect the Magallanes region modeled by America/Punta_Arenas. (Thanks to Juan Correa and Tim Parenti.) Adjust future predictions accordingly. Changes to past timestamps The 2018-05-05 North Korea 30-minute time zone change took place at 23:30 the previous day, not at 00:00 that day. China's 1988 spring-forward transition was on April 17, not April 10. Its DST transitions in 1986/91 were at 02:00, not 00:00. (Thanks to P Chan.) Fix several issues for Macau before 1992. Macau's pre-1904 LMT was off by 10 s. Macau switched to +08 in 1904 not 1912, and temporarily switched to +09/+10 during World War II. Macau observed DST in 1942/79, not 1961/80, and there were several errors for transition times and dates. (Thanks to P Chan.) The 1948-1951 fallback transitions in Japan were at 25:00 on September's second Saturday, not at 24:00. (Thanks to Phake Nick.) zic turns this into 01:00 on the day after September's second Saturday, which is the best that POSIX or C platforms can do. Incorporate 1940-1949 Asia/Shanghai DST transitions from a 2014 paper by Li Yu, replacing more-questionable data from Shanks. Changes to time zone abbreviations Use "PST" and "PDT" for Philippine time. (Thanks to Paul Goyette.) Changes to documentation New restrictions: A Rule name must start with a character that is neither an ASCII digit nor "-" nor "+", and an unquoted name should not use characters in the set "!$%&'()*,/:;<=>?@[\]^`{|}~". The latter restriction makes room for future extensions (a possibility noted by Tom Lane). tzfile.5 now documents what time types apply before the first and after the last transition, if any. Documentation now uses the spelling "timezone" for a TZ setting that determines timestamp history, and "time zone" for a geographic region currently sharing the same standard time. The name "TZif" is now used for the tz binary data format. tz-link.htm now mentions the A0 TimeZone Migration utilities. (Thanks to Aldrin Martoq for the link.) Changes to build procedure New 'make' target 'rearguard_tarballs' to build the rearguard tarball only. This is a convenience on platforms that lack lzip if you want to build the rearguard tarball. (Problem reported by Deborah Goldsmith.) tzdata.zi is now more stable from release to release. (Problem noted by Tom Lane.) It is also a bit shorter. tzdata.zi now can contain comment lines documenting configuration information, such as which data format was selected, which input files were used, and how leap seconds are treated. (Problems noted by Lester Caine and Brian Inglis.) If the Makefile defaults are used these comment lines are absent, for backward compatibility. A redistributor intending to alter its copy of the files should also append "-LABEL" to the 'version' file's first line, where "LABEL" identifies the redistributor's change.

tzdata: update to 2018e

2018-05-15T09:56:49+00:00

Briefly: North Korea switches back to +09 on 2018-05-05. The main format uses negative DST again, for Ireland etc. 'make tarballs' now also builds a rearguard tarball. New 's' and 'd' suffixes in SAVE columns of Rule and Zone lines. Changes to past and future time stamps North Korea switches back from +0830 to +09 on 2018-05-05. (Thanks to Kang Seonghoon, Arthur David Olson, Seo Sanghyeon, and Tim Parenti.) Bring back the negative-DST changes of 2018a, except be more compatible with data parsers that do not support negative DST. Also, this now affects historical time stamps in Namibia and the former Czechoslovakia, not just Ireland. The main format now uses negative DST to model time stamps in Europe/Dublin (from 1971 on), Europe/Prague (1946/7), and Africa/Windhoek (1994/2017). This does not affect UT offsets, only time zone abbreviations and the tm_isdst flag. Also, this does not affect rearguard or vanguard formats; effectively the main format now uses vanguard instead of rearguard format. Data parsers that do not support negative DST can still use data from the rearguard tarball described below (From OE-Core rev: f717eeff2d4823163cb72fb79101220cc48b3286) Signed-off-by: Armin Kuster Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

tzdata: update to 2018c

2018-01-26T13:09:10+00:00

The 2018c release of the tz code and data is available. It follows on the 2018a and 2018b releases, which were published but were not announced until now, due to problems discovered late in their release processes. 2018a had a build-failure typo, and 2018a and 2018b both had problems with ICU and Java, downstream packages which do not support a feature (negative DST offsets) used in 2018a and 2018b. The typo has been fixed, and data changes using negative DST offsets have been reverted pending development of a mechanism to export data to platforms lacking support for such data. Briefly: São Tomé and Príncipe switched from +00 to +01. Brazil's DST will now start on November's first Sunday. Use Debian-style installation locations, instead of 4.3BSD-style. New zic option -t. Changes to past and future time stamps São Tomé and Príncipe switched from +00 to +01 on 2018-01-01 at 01:00. (Thanks to Steffen Thorsen and Michael Deckers.) Changes to future time stamps Starting in 2018 southern Brazil will begin DST on November's first Sunday instead of October's third Sunday. (Thanks to Steffen Thorsen.) Changes to past time stamps Japanese DST transitions (1948-1951) were Sundays at 00:00, not Saturdays or Sundays at 02:00. (Thanks to Takayuki Nikai.) A discrepancy of 4 s in timestamps before 1931 in South Sudan has been corrected. The 'backzone' and 'zone.tab' files did not agree with the 'africa' and 'zone1970.tab' files. (Problem reported by Michael Deckers.) The abbreviation invented for Bolivia Summer Time (1931-2) is now BST instead of BOST, to be more consistent with the convention used for Latvian Summer Time (1918-9) and for British Summer Time. Changes to build procedure The default installation locations have been changed to mostly match Debian circa 2017, instead of being designed as an add-on to 4.3BSD circa 1986. This affects the Makefile macros TOPDIR, TZDIR, MANDIR, and LIBDIR. New Makefile macros TZDEFAULT, USRDIR, USRSHAREDIR, BINDIR, ZDUMPDIR, and ZICDIR let installers tailor locations more precisely. (This responds to suggestions from Brian Inglis and from Steve Summit.) The default installation procedure no longer creates the backward-compatibility link US/Pacific-New, which causes confusion during user setup (e.g., see Debian bug 815200). Use 'make BACKWARD="backward pacificnew"' to create the link anyway, for now. Eventually we plan to remove the link entirely. tzdata.zi now contains a version-number comment. (Suggested by Tom Lane.) The Makefile now quotes values like BACKWARD more carefully when passing them to the shell. (Problem reported by Zefram.) Builders no longer need to specify -DHAVE_SNPRINTF on platforms that have snprintf and use pre-C99 compilers. (Problem reported by Jon Skeet.) The build procedure now works around mawk 1.3.3's lack of support for character class expressions. (Problem reported by Ohyama.)

Fiji ends DST 2018-01-14, not 2018-01-21. Namibia switches from +01/+02 to +02 on 2018-04-01. Sudan switches from +03 to +02 on 2017-11-01. Tonga likely switches from +13/+14 to +13 on 2017-11-05. Turks & Caicos switches from -04 to -05/-04 on 2018-11-04. A new file tzdata.zi now holds a small text copy of all data. The zic input format has been regularized slightly. Changes to future time stamps Northern Cyprus has decided to resume EU rules starting 2017-10-29, thus reinstituting winter time. Fiji ends DST 2018-01-14 instead of the 2018-01-21 previously predicted. (Thanks to Dominic Fok.) Adjust future predictions accordingly. Namibia will switch from +01 with DST to +02 all year on 2017-09-03 at 02:00. This affects UT offsets starting 2018-04-01 at 02:00. (Thanks to Steffen Thorsen.) Sudan will switch from +03 to +02 on 2017-11-01. (Thanks to Ahmed Atyya and Yahia Abdalla.) South Sudan is not switching, so Africa/Juba is no longer a link to Africa/Khartoum. Tonga has likely ended its experiment with DST, and will not adjust its clocks on 2017-11-05. Although Tonga has not announced whether it will continue to observe DST, the IATA is assuming that it will not. (Thanks to David Wade.) Turks & Caicos will switch from -04 all year to -05 with US DST on 2018-03-11 at 03:00. This affects UT offsets starting 2018-11-04 at 02:00. (Thanks to Steffen Thorsen.) Changes to past time stamps Namibia switched from +02 to +01 on 1994-03-21, not 1994-04-03. (Thanks to Arthur David Olson.) Detroit did not observe DST in 1967. Use railway time for Asia/Kolkata before 1941, by switching to Madras local time (UT +052110) in 1870, then to IST (UT +0530) in 1906. Also, treat 1941-2's +0630 as DST, like 1942-5. Europe/Dublin's 1946 and 1947 fallback transitions occurred at 02:00 standard time, not 02:00 DST. (Thanks to Michael Deckers.) Pacific/Apia and Pacific/Pago_Pago switched from Antipodean to American time in 1892, not 1879. (Thanks to Michael Deckers.) Adjust the 1867 transition in Alaska to better reflect the historical record, by changing it to occur on 1867-10-18 at 15:30 Sitka time rather than at the start of 1867-10-17 local time. Although strictly speaking this is accurate only for Sitka, the rest of Alaska's blanks need to be filled in somehow. Fix off-by-one errors in UT offsets for Adak and Nome before 1867. (Thanks to Michael Deckers.) Add 7 s to the UT offset in Asia/Yangon before 1920. Changes to zone names Remove Canada/East-Saskatchewan from the 'backward' file, as it exceeded the 14-character limit and was an unused misnomer anyway.
