+Release 2018h - 2018-12-23 17:59:32 -0800
+
+ 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. (Thanks to Matt Johnson.)

+# same month, but there were not much information about time there. Later they
+# started including a radio program guide when they restored radio service,
+# explicitly mentioning it use Tokyo standard time, and later added a note
+# saying it's half an hour ahead of the old Hong Kong standard time, and it
+# also seems to indicate that Hong Kong was not using GMT+8 when it was

+# British astronomer Henry Park Hollis disliked India Standard Time's offset:
+# "A new time system has been proposed for India, Further India, and Burmah.
+# The scheme suggested is that the times of the meridians 5½ and 6½ hours
+# east of Greenwich should be adopted in these territories. No reason is
+# given why hourly meridians five hours and six hours east should not be
+# chosen; a plan which would bring the time of India into harmony with
