News for the tz database
+Release 2014j - 2014-11-10 17:37:11 -0800
+
+ Changes affecting current and future time stamps
+
+ Turks & Caicos' switch from US eastern time to UTC-4 year-round
+ did not occur on 2014-11-02 at 02:00. It's currently scheduled
+ for 2015-11-01 at 02:00. (Thanks to Chris Walton.)
+
+ Changes affecting past time stamps
+
+ Many pre-1989 time stamps have been corrected for Asia/Seoul and
+ Asia/Pyongyang, based on sources for the Korean-language Wikipedia
+ entry for time in Korea. (Thanks to Sanghyuk Jung.) Also, no
+ longer guess that Pyongyang mimicked Seoul time after World War II,
+ as this is politically implausible.
+
+ 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/Addis_Ababa, Africa/Asmara,
+ Africa/Dar_es_Salaam, Africa/Djibouti, Africa/Kampala,
+ Africa/Mogadishu, Indian/Antananarivo, Indian/Comoro, and
+ Indian/Mayotte.
+
+ Changes affecting commentary
+
+ The commentary is less enthusiastic about Shanks as a source,
+ and is more careful to distinguish UT from UTC.
+
+
+Release 2014i - 2014-10-21 22:04:57 -0700
+
+ Changes affecting future time stamps
+
+ Pacific/Fiji will observe DST from 2014-11-02 02:00 to 2015-01-18 03:00.
+ (Thanks to Ken Rylander for the heads-up.) Guess that future
+ years will use a similar pattern.
+
+ 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.
+ (Thanks to Kiley Walbom for the heads-up.)
+
+ Changes affecting time zone abbreviations
+
+ 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.
+ (Thanks to Alexander Bokovoy for the heads-up about Belarus.)
+
+ The new abbreviation IDT stands for the pre-1976 use of UT+8 in
+ Indochina, to distinguish it better from ICT (UT+7).
+
+ Changes affecting past time stamps
+
+ Many time stamps have been corrected for Asia/Ho_Chi_Minh before 1976
+ (thanks to Trần Ngọc Quân for an indirect pointer to Trần Tiến Bình's
+ authoritative book). Asia/Ho_Chi_Minh has been added to
+ zone1970.tab, to give tzselect users in Vietnam two choices,
+ since north and south Vietnam disagreed after our 1970 cutoff.
+
+ Asia/Phnom_Penh and Asia/Vientiane have been turned into links, as
+ they differed from existing zones only for older time stamps. As
+ usual, these changes affect pre-1970 time stamps only. Their old
+ contents have been moved to the 'backzone' file.
+
+ Changes affecting code
+
+ The time-related library functions now set errno on failure, and
+ some crashes in the new tzalloc-related library functions have
+ been fixed. (Thanks to Christos Zoulas for reporting most of
+ these problems and for suggesting fixes.)
+
+ If USG_COMPAT is defined and the requested time stamp is standard time,
+ the tz library's localtime and mktime functions now set the extern
+ variable timezone to a value appropriate for that time stamp; and
+ similarly for ALTZONE, daylight saving time, and the altzone variable.
+ This change is a companion to the tzname change in 2014h, and is
+ designed to make timezone and altzone more compatible with tzname.
+
+ The tz library's functions now set errno to EOVERFLOW if they fail
+ because the result cannot be represented. ctime and ctime_r now
+ return NULL and set errno when a time stamp is out of range, rather
+ than having undefined behavior.
+
+ Some bugs associated with the new 2014g functions have been fixed.
+ This includes a bug that largely incapacitated the new functions
+ time2posix_z and posix2time_z. (Thanks to Christos Zoulas.)
+ It also includes some uses of uninitialized variables after tzalloc.
+ The new code uses the standard type 'ssize_t', which the Makefile
+ now gives porting advice about.
+
+ Changes affecting commentary
+
+ Updated URLs for NRC Canada (thanks to Matt Johnson and Brian Inglis).
+
+
+Release 2014h - 2014-09-25 18:59:03 -0700
+
+ Changes affecting past time stamps
+
+ America/Jamaica's 1974 spring-forward transition was Jan. 6, not Apr. 28.
+
+ Shanks says Asia/Novokuznetsk switched from LMT (not "NMT") on 1924-05-01,
+ not 1920-01-06. The old entry was based on a misinterpretation of Shanks.
+
+ 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.
+
+ Changes affecting code
+
+ zdump -V and -v now output gmtoff= values on all platforms,
+ not merely on platforms defining TM_GMTOFF.
+
+ The tz library's localtime and mktime functions now set tzname to a value
+ appropriate for the requested time stamp, and zdump now uses this
+ on platforms not defining TM_ZONE, fixing a 2014g regression.
+ (Thanks to Tim Parenti for reporting the problem.)
+
+ The tz library no longer sets tzname if localtime or mktime fails.
+
+ zdump -c no longer mishandles transitions near year boundaries.
+ (Thanks to Tim Parenti for reporting the problem.)
+
+ An access to uninitalized data has been fixed.
+ (Thanks to Jörg Richter for reporting the problem.)
+
+ When THREAD_SAFE is defined, the code ports to the C11 memory model.
+ A memory leak has been fixed if ALL_STATE and THREAD_SAFE are defined
+ and two threads race to initialize data used by gmtime-like functions.
+ (Thanks to Andy Heninger for reporting the problems.)
+
+ Changes affecting build procedure
+
+ 'make check' now checks better for properly-sorted data.
+
+ Changes affecting documentation and commentary
+
+ zdump's gmtoff=N output is now documented, and its isdst=D output
+ is now documented to possibly output D values other than 0 or 1.
+
+ zdump -c's treatment of years is now documented to use the
+ Gregorian calendar and Universal Time without leap seconds,
+ and its behavior at cutoff boundaries is now documented better.
+ (Thanks to Arthur David Olson and Tim Parenti for reporting the problems.)
+
+ Programs are now documented to use the proleptic Gregorian calendar.
+ (Thanks to Alan Barrett for the suggestion.)
+
+ Fractional-second GMT offsets have been documented for civil time
+ in 19th-century Chennai, Jakarta, and New York.
+
+
Release 2014g - 2014-08-28 12:31:23 -0700
Changes affecting future time stamps
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.
+ [As noted in 2014j, this switch was later delayed.]

+# From Paul Eggert (2014-10-21) after a heads-up from Trần Ngọc Quân:
+# Trần Tiến Bình's authoritative book "Lịch Việt Nam: thế kỷ XX-XXI (1901-2100)"
+# (Nhà xuất bản Văn Hoá - Thông Tin, Hanoi, 2005), pp 49-50,
+# is quoted verbatim in:
+# http://www.thoigian.com.vn/?mPage=P80D01
+# is translated by Brian Inglis in:
+# http://mm.icann.org/pipermail/tz/2014-October/021654.html
+# and is the basis for the information below.
+#
+# The 1906 transition was effective July 1 and standardized Indochina to
+# Phù Liễn Observatory, legally 104 deg. 17'17" east of Paris.
+# It's unclear whether this meant legal Paris Mean Time (00:09:21) or
+# the Paris Meridian (2 deg. 20'14.03" E); the former yields 07:06:30.1333...
+# and the latter 07:06:29.333... so either way it rounds to 07:06:30,
+# which is used below even though the modern-day Phù Liễn Observatory
+# is closer to 07:06:31. Abbreviate Phù Liễn Mean Time as PLMT.
+#
+# The following transitions occurred in Indochina in general (before 1954)
+# and in South Vietnam in particular (after 1954):
+# To 07:00 on 1911-05-01.
+# To 08:00 on 1942-12-31 at 23:00.
+# To 09:00 in 1945-03-14 at 23:00.
+# To 07:00 on 1945-09-02 in Vietnam.
+# To 08:00 on 1947-04-01 in French-controlled Indochina.
+# To 07:00 on 1955-07-01 in South Vietnam.
