Import tzdata2016h from ftp://ftp.iana.org/tz/releases/tzdata2016h.tar.gz
Summary of changes in tzdata2016h (2016-10-19 23:17:57 -0700): Asia/Gaza and Asia/Hebron end of summer time for 2016 is 2016-10-29 at 01:00 rather than 2016-10-21 at 00:00 (which is within hours after this update). Guess that future end dates will be the last Sat of October. Corrected some historic time (and one date) transition times for Turkey (all 1990 or before.) Switch Sri-Lanka to use numeric abbreviation for time zone as the tzdata invented one is not correct, and the correct one seems not to be widely used.

|
||||
|
||||
Changes to future time stamps
|
||||
|
||||
Asia/Gaza and Asia/Hebron end DST on 2016-10-29 at 01:00, not
|
||||
2016-10-21 at 00:00. (Thanks to Sharef Mustafa.) Predict that
|
||||
future fall transitions will be on the last Saturday of October
|
||||
at 01:00, which is consistent with predicted spring transitions
|
||||
on the last Saturday of March. (Thanks to Tim Parenti.)
|
||||
|
||||
Changes to past time stamps
|
||||
|
||||
In Turkey, transitions in 1986-1990 were at 01:00 standard time
|
||||
not at 02:00, and the spring 1994 transition was on March 20, not
|
||||
March 27. (Thanks to Kıvanç Yazan.)
|
||||
|
||||
Changes to past and future time zone abbreviations
|
||||
|
||||
Asia/Colombo now uses numeric time zone abbreviations like "+0530"
|
||||
instead of alphabetic ones like "IST" and "LKT". Various
|
||||
English-language sources use "IST", "LKT" and "SLST", with no
|
||||
working consensus. (Usage of "SLST" mentioned by Sadika
|
||||
Sumanapala.)
|
||||
|
||||
Changes to code
|
||||
|
||||
zic no longer mishandles relativizing file names when creating
|
||||
symbolic links like /etc/localtime, when these symbolic links
|
||||
are outside the usual directory hierarchy. This fixes a bug
|
||||
introduced in 2016g. (Problem reported by Andreas Stieger.)
|
||||
|
||||
Changes to build procedure
|
||||
|
||||
New rules 'traditional_tarballs' and 'traditional_signatures' for
|
||||
building just the traditional-format distribution. (Requested by
|
||||
Deborah Goldsmith.)
|
||||
|
||||
The file 'version' is now put into the tzdata tarball too.
|
||||
(Requested by Howard Hinnant.)
|
||||
|
||||
Changes to documentation and commentary
|
||||
|
||||
The 'Theory' file now has a section on interface stability.
|
||||
(Requested by Paul Koning.) It also mentions features like
|
||||
tm_zone and localtime_rz that have long been supported by the
|
||||
reference code.
|
||||
|
||||
tz-link.htm has improved coverage of time zone boundaries suitable
|
||||
for geolocation. (Thanks to heads-ups from Evan Siroky and Matt
|
||||
Johnson.)
|
||||
|
||||
The US commentary now mentions Allen and the "day of two noons".
|
||||
|
||||
The Fiji commentary mentions the government's 2016-10-03 press
|
||||
release. (Thanks to Raymond Kumar.)

----- Interface stability -----
|
||||
|
||||
The tz code and data supply the following interfaces:
|
||||
|
||||
* A set of zone names as per "Names of time zone rules" above.
|
||||
|
||||
* Library functions described in "Time and date functions" above.
|
||||
|
||||
* The programs tzselect, zdump, and zic, documented in their man pages.
|
||||
|
||||
* The format of zic input files, documented in the zic man page.
|
||||
|
||||
* The format of zic output files, documented in the tzfile man page.
|
||||
|
||||
* The format of zone table files, documented in zone1970.tab.
|
||||
|
||||
* The format of the country code file, documented in iso3166.tab.
|
||||
|
||||
When these interfaces are changed, an effort is made to preserve
|
||||
backward compatibility. For example, tz data files typically do not
|
||||
rely on recently-added zic features, so that users can run older zic
|
||||
versions to process newer data files.
|
||||
|
||||
Interfaces not listed above are less stable. For example, users
|
||||
should not rely on particular UT offsets or abbreviations for time
|
||||
stamps, as data entries are often based on guesswork and these guesses
|
||||
may be corrected or improved.
