News for the tz database
+Release 2017c - 2017-10-20 14:49:34 -0700
+
+ Briefly:
+ Northern Cyprus switches from +03 to +02/+03 on 2017-10-29.
+ 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.
+
+ Changes to build procedure
+
+ To support applications that prefer to read time zone data in text
+ form, two zic input files tzdata.zi and leapseconds are now
+ installed by default. The commands 'zic tzdata.zi' and 'zic -L
+ leapseconds tzdata.zi' can reproduce the tzdata binary files
+ without and with leap seconds, respectively. To prevent these two
+ new files from being installed, use 'make TZDATA_TEXT=', and to
+ suppress leap seconds from the tzdata text installation, use 'make
+ TZDATA_TEXT=tzdata.zi'.
+
+ 'make BACKWARD=' now suppresses backward-compatibility names
+ like 'US/Pacific' that are defined in the 'backward' and
+ 'pacificnew' files.
+
+ 'make check' now works on systems that lack a UTF-8 locale,
+ or that lack the nsgmls program. Set UTF8_LOCALE to configure
+ the name of a UTF-8 locale, if you have one.
+
+ Y2K runtime checks are no longer enabled by default. Add
+ -DDEPRECATE_TWO_DIGIT_YEARS to CFLAGS to enable them, instead of
+ adding -DNO_RUN_TIME_WARNINGS_ABOUT_YEAR_2000_PROBLEMS_THANK_YOU
+ to disable them. (New name suggested by Brian Inglis.)
+
+ The build procedure for zdump now works on AIX 7.1.
+ (Problem reported by Kees Dekker.)
+
+ Changes to code
+
+ zic and the reference runtime now reject multiple leap seconds
+ within 28 days of each other, or leap seconds before the Epoch.
+ As a result, support for double leap seconds, which was
+ obsolescent and undocumented, has been removed. Double leap
+ seconds were an error in the C89 standard; they have never existed
+ in civil timekeeping. (Thanks to Robert Elz and Bradley White for
+ noticing glitches in the code that uncovered this problem.)
+
+ zic now warns about use of the obsolescent and undocumented -y
+ option, and about use of the obsolescent TYPE field of Rule lines.
+
+ zic now allows unambiguous abbreviations like "Sa" and "Su" for
+ weekdays; formerly it rejected them due to a bug. Conversely, zic
+ no longer considers non-prefixes to be abbreviations; for example,
+ it no longer accepts "lF" as an abbreviation for "lastFriday".
+ Also, zic warns about the undocumented usage with a "last-"
+ prefix, e.g., "last-Fri".
+
+ Similarly, zic now accepts the unambiguous abbreviation "L" for
+ "Link" in ordinary context and for "Leap" in leap-second context.
+ Conversely, zic no longer accepts non-prefixes such as "La" as
+ abbreviations for words like "Leap".
+
+ zic no longer accepts leap second lines in ordinary input, or
+ ordinary lines in leap second input. Formerly, zic sometimes
+ warned about this undocumented usage and handled it incorrectly.
+
+ The new macro HAVE_TZNAME governs whether the tzname external
+ variable is exported, instead of USG_COMPAT. USG_COMPAT now
+ governs only the external variables "timezone" and "daylight".
+ This change is needed because the three variables are not in the
+ same category: although POSIX requires tzname, it specifies the
+ other two variables as optional. Also, USG_COMPAT is now 1 or 0:
+ if not defined, the code attempts to guess it from other macros.
+
+ localtime.c and difftime.c no longer require stdio.h, and .c files
+ other than zic.c no longer require sys/wait.h.
+
+ zdump.c no longer assumes snprintf. (Reported by Jonathan Leffler.)
+
+ Calculation of time_t extrema works around a bug in GCC 4.8.4
+ (Reported by Stan Shebs and Joseph Myers.)
+
+ zic.c no longer mistranslates formats of line numbers in non-English
+ locales. (Problem reported by Benno Schulenberg.)
+
+ Several minor changes have been made to the code to make it a
+ bit easier to port to MS-Windows and Solaris. (Thanks to Kees
+ Dekker for reporting the problems.)
+
+ Changes to documentation and commentary
+
+ The two new files 'theory.html' and 'calendars' contain the
+ contents of the removed file 'Theory'. The goal is to document
+ tzdb theory more accessibly.
+
+ The zic man page now documents abbreviation rules.
+
+ tz-link.htm now covers how to apply tzdata changes to clients.
+ (Thanks to Jorge Fábregas for the AIX link.) It also mentions MySQL.
+
+ The leap-seconds.list URL has been updated to something that is
+ more reliable for tzdb. (Thanks to Tim Parenti and Brian Inglis.)
+
+Release 2017b - 2017-03-17 07:30:38 -0700
+
+ Briefly: Haiti has resumed DST.
+
+ Changes to past and future time stamps
+
+ Haiti resumed observance of DST in 2017. (Thanks to Steffen Thorsen.)
+
+ Changes to past time stamps
+
+ Liberia changed from -004430 to +00 on 1972-01-07, not 1972-05-01.
+
+ Use "MMT" to abbreviate Liberia's time zone before 1972, as "-004430"
+ is one byte over the POSIX limit. (Problem reported by Derick Rethans.)
+
+ Changes to code
+
+ The reference localtime implementation now falls back on the
+ current US daylight-saving transition rules rather than the
+ 1987-2006 rules. This fallback occurs only when (1) the TZ
+ environment variable's value has a name like "AST4ADT" that asks
+ for daylight saving time but does not specify the rules, (2) there
+ is no file by that name, and (3) the TZDEFRULES file cannot be
+ loaded. (Thanks to Tom Lane.)
+
+
+Release 2017a - 2017-02-28 00:05:36 -0800
+
+ Briefly: Southern Chile moves from -04/-03 to -03, and Mongolia
+ discontinues DST.
+
+ Changes to future time stamps
+
+ Mongolia no longer observes DST. (Thanks to Ganbold Tsagaankhuu.)
+
+ Chile's Region of Magallanes moves from -04/-03 to -03 year-round.
+ Its clocks diverge from America/Santiago starting 2017-05-13 at
+ 23:00, hiving off a new zone America/Punta_Arenas. Although the
+ Chilean government says this change expires in May 2019, for now
+ assume it's permanent. (Thanks to Juan Correa and Deborah
+ Goldsmith.) This also affects Antarctica/Palmer.
+
+ Changes to past time stamps
+
+ Fix many entries for historical time stamps for Europe/Madrid
+ before 1979, to agree with tables compiled by Pere Planesas of the
+ National Astronomical Observatory of Spain. As a side effect,
+ this changes some time stamps for Africa/Ceuta before 1929, which
+ are probably guesswork anyway. (Thanks to Steve Allen and
+ Pierpaolo Bernardi for the heads-ups, and to Michael Deckers for
+ correcting the 1901 transition.)
+
+ Ecuador observed DST from 1992-11-28 to 1993-02-05.
+ (Thanks to Alois Treindl.)
+
+ Asia/Atyrau and Asia/Oral were at +03 (not +04) before 1930-06-21.
+ (Thanks to Stepan Golosunov.)
+
+ Changes to past and future time zone abbreviations
+
+ Switch to numeric time zone abbreviations for South America, as
+ part of the ongoing project of removing invented abbreviations.
+ This avoids the need to invent an abbreviation for the new Chilean
+ new zone. Similarly, switch from invented to numeric time zone
+ abbreviations for Afghanistan, American Samoa, the Azores,
+ Bangladesh, Bhutan, the British Indian Ocean Territory, Brunei,
+ Cape Verde, Chatham Is, Christmas I, Cocos (Keeling) Is, Cook Is,
+ Dubai, East Timor, Eucla, Fiji, French Polynesia, Greenland,
+ Indochina, Iran, Iraq, Kiribati, Lord Howe, Macquarie, Malaysia,
+ the Maldives, Marshall Is, Mauritius, Micronesia, Mongolia,
+ Myanmar, Nauru, Nepal, New Caledonia, Niue, Norfolk I, Palau,
+ Papua New Guinea, the Philippines, Pitcairn, Qatar, Réunion, St
+ Pierre & Miquelon, Samoa, Saudi Arabia, Seychelles, Singapore,
+ Solomon Is, Tokelau, Tuvalu, Wake, Vanuatu, Wallis & Futuna, and
+ Xinjiang; for 20-minute daylight saving time in Ghana before 1943;
+ for half-hour daylight saving time in Belize before 1944 and in
+ the Dominican Republic before 1975; and for Canary Islands before
+ 1946, for Guinea-Bissau before 1975, for Iceland before 1969, for
+ Indian Summer Time before 1942, for Indonesia before around 1964,
+ for Kenya before 1960, for Liberia before 1973, for Madeira before
+ 1967, for Namibia before 1943, for the Netherlands in 1937-9, for
+ Pakistan before 1971, for Western Sahara before 1977, and for
+ Zaporozhye in 1880-1924.
+
+ For Alaska time from 1900 through 1967, instead of "CAT" use the
+ abbreviation "AST", the abbreviation commonly used at the time
+ (Atlantic Standard Time had not been standardized yet). Use "AWT"
+ and "APT" instead of the invented abbreviations "CAWT" and "CAPT".
+
+ Use "CST" and "CDT" instead of invented abbreviations for Macau
+ before 1999 and Taiwan before 1938, and use "JST" instead of the
+ invented abbreviation "JCST" for Japan and Korea before 1938.
+
+ Change to database entry category
+
+ Move the Pacific/Johnston link from 'australasia' to 'backward',
+ since Johnston is now uninhabited.
+
+ Changes to code
+
+ zic no longer mishandles some transitions in January 2038 when it
+ attempts to work around Qt bug 53071. This fixes a bug affecting
+ Pacific/Tongatapu that was introduced in zic 2016e. localtime.c
+ now contains a workaround, useful when loading a file generated by
+ a buggy zic. (Problem and localtime.c fix reported by Bradley
+ White.)
+
+ zdump -i now outputs non-hour numeric time zone abbreviations
+ without a colon, e.g., "+0530" rather than "+05:30". This agrees
+ with zic %z and with common practice, and simplifies auditing of
+ zdump output.
+
+ zdump is now buildable again with -DUSE_LTZ=0.
+ (Problem reported by Joseph Myers.)
+
+ zdump.c now always includes private.h, to avoid code duplication
+ with private.h. (Problem reported by Kees Dekker.)
+
+ localtime.c no longer mishandles early or late timestamps
+ when TZ is set to a POSIX-style string that specifies DST.
+ (Problem reported by Kees Dekker.)
+
+ date and strftime now cause %z to generate "-0000" instead of
+ "+0000" when the UT offset is zero and the time zone abbreviation
+ begins with "-".
+
+ Changes to documentation and commentary
+
+ The 'Theory' file now better documents choice of historical time
+ zone abbreviations. (Problems reported by Michael Deckers.)
+
+ tz-link.htm now covers leap smearing, which is popular in clouds.
+
+
+Release 2016j - 2016-11-22 23:17:13 -0800
+
+ Briefly: Saratov, Russia moves from +03 to +04 on 2016-12-04.
+
+ Changes to future time stamps
+
+ Saratov, Russia switches from +03 to +04 on 2016-12-04 at 02:00.
+ This hives off a new zone Europe/Saratov from Europe/Volgograd.
+ (Thanks to Yuri Konotopov and Stepan Golosunov.)
+
+ Changes to past time stamps
+
+ The new zone Asia/Atyrau for Atyraū Region, Kazakhstan, is like
+ Asia/Aqtau except it switched from +05/+06 to +04/+05 in spring
+ 1999, not fall 1994. (Thanks to Stepan Golosunov.)
+
+ Changes to past time zone abbreviations
+
+ Asia/Gaza and Asia/Hebron now use "EEST", not "EET", to denote
+ summer time before 1948. The old use of "EET" was a typo.
+
+ Changes to code
+
+ zic no longer mishandles file systems that lack hard links, fixing
+ bugs introduced in 2016g. (Problems reported by Tom Lane.)
+ Also, when the destination already contains symbolic links, zic
+ should now work better on systems where the 'link' system call
+ does not follow symbolic links.
+
+ Changes to documentation and commentary
+
+ tz-link.htm now documents the relationship between release version
+ numbers and development-repository commit tags. (Suggested by
+ Paul Koning.)
+
+ The 'Theory' file now documents UT.
+
+ iso3166.tab now accents "Curaçao", and commentary now mentions
