News for the tz database
+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,

+ 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.

-# To make things confusing, 'WAT' seems to have been used for -1:00 long ago;

+# times. The people called it "hora de Sixto" ("Sixto hour"). The change did
+# not go over well; a popular song "Qué hora es" by Jaime Guevara had lyrics
+# that included "Amanecía en mitad de la noche, los guaguas iban a clase sin
+# sol" ("It was dawning in the middle of the night, the buses went to class
+# without sun"). Although Ballén's campaign slogan was "Ni un paso atrás"
+# (Not one step back), the clocks went back in 1993 and the experiment was not
+# repeated. For now, assume transitions were at 00:00 local time country-wide.
