This year Fiji will start DST on October 27, not October 20. This year Fiji will start DST on October 27, not October 20.
(Thanks to David Wheeler for the heads-up.) For now, guess that
Fiji will continue to spring forward the Sunday before the fourth
Monday in October.
- Changes affecting current and future time zone abbreviations
Use WIB/WITA/WIT rather than WIT/CIT/EIT for alphabetic Indonesian Use WIB/WITA/WIT rather than WIT/CIT/EIT for alphabetic Indonesian
time zone abbreviations since 1932. (Thanks to George Ziegler, time zone abbreviations since 1932
Priyadi Iman Nurcahyo, Zakaria, Jason Grimes, Martin Pitt, and
Benny Lin.) This affects Asia/Dili, Asia/Jakarta, Asia/Jayapura,
Asia/Makassar, and Asia/Pontianak.

range from -167 through 167, instead of the POSIX-required 0 * The 'leapseconds' file is now generated automatically from a
through 24. E.g., TZ='FJT-12FJST,M10.3.1/146,M1.3.4/75' for the
new Fiji rules. This is a more-compact way to represent
far-future time stamps for America/Godthab, America/Santiago,
Antarctica/Palmer, Asia/Gaza, Asia/Hebron, Asia/Jerusalem,
Pacific/Easter, and Pacific/Fiji. Other zones are unaffected by
this change. (Derived from a suggestion by Arthur David Olson.)
Allow POSIX-like TZ strings where daylight saving time is in
effect all year. E.g., TZ='WART4WARST,J1/0,J365/25' for Western
Argentina Summer Time all year. This supports a more-compact way
to represent the 2013d data for America/Argentina/San_Luis.
Because of the change for San Luis noted above this change does not
affect the current data. (Thanks to Andrew Main (Zefram) for
suggestions that improved this change.)
Where these two TZ changes take effect, there is a minor extension
to the tz file format in that it allows new values for the
embedded TZ-format string, and the tz file format version number
has therefore been increased from 2 to 3 as a precaution.
Version-2-based client code should continue to work as before for
all time stamps before 2038. Existing version-2-based client code
(tzcode, GNU/Linux, Solaris) has been tested on version-3-format
files, and typically works in practice even for time stamps after
2037; the only known exception is America/Godthab.
Changes affecting time stamps before 1970
Pacific/Johnston is now a link to Pacific/Honolulu. This corrects
some errors before 1947.
Some zones have been turned into links, when they differ from
existing zones only in older data that was likely invented or that
differs only in LMT or transition from LMT. These changes affect
only time stamps before 1943. The affected zones are:
Africa/Juba, America/Anguilla, America/Aruba, America/Dominica,
America/Grenada, America/Guadeloupe, America/Marigot,
America/Montserrat, America/St_Barthelemy, America/St_Kitts,
America/St_Lucia, America/St_Thomas, America/St_Vincent,
America/Tortola, and Europe/Vaduz. (Thanks to Alois Treindl for
confirming that the old Europe/Vaduz zone was wrong and the new
link is better for WWII-era times.)
Change Kingston Mean Time from -5:07:12 to -5:07:11. This affects
America/Cayman, America/Jamaica and America/Grand_Turk time stamps
from 1890 to 1912.
Change the UT offset of Bern Mean Time from 0:29:44 to 0:29:46.
This affects Europe/Zurich time stamps from 1853 to 1894. (Thanks
to Alois Treindl).
Change the date of the circa-1850 Zurich transition from 1849-09-12
to 1853-07-16, overriding Shanks with data from Messerli about
postal and telegraph time in Switzerland.
Changes affecting time zone abbreviations before 1970
For Asia/Jakarta, use BMT (not JMT) for mean time from 1923 to 1932,
as Jakarta was called Batavia back then.
Changes affecting API
The 'zic' command now outputs a dummy transition when far-future
data can't be summarized using a TZ string, and uses a 402-year
window rather than a 400-year window. For the current data, this
affects only the Asia/Tehran file. It does not affect any of the
time stamps that this file represents, so zdump outputs the same
information as before. (Thanks to Andrew Main (Zefram).)
The 'date' command has a new '-r' option, which lets you specify
the integer time to display, a la FreeBSD.
The 'tzselect' command has two new options '-c' and '-n', which lets you
select a zone based on latitude and longitude.
The 'zic' command's '-v' option now warns about constructs that
require the new version-3 binary file format. (Thanks to Arthur
David Olson for the suggestion.)
Support for floating-point time_t has been removed.
It was always dicey, and POSIX no longer requires it.
(Thanks to Eric Blake for suggesting to the POSIX committee to
remove it, and thanks to Alan Barrett, Clive D.W. Feather, Andy
Heninger, Arthur David Olson, and Alois Treindl, for reporting
bugs and elucidating some of the corners of the old floating-point
implementation.)
The signatures of 'offtime', 'timeoff', and 'gtime' have been
changed back to the old practice of using 'long' to represent UT
offsets. This had been inadvertently and mistakenly changed to
'int_fast32_t'. (Thanks to Christos Zoulos.)
The code avoids undefined behavior on integer overflow in some
more places, including gmtime, localtime, mktime and zdump.
Changes affecting the zdump utility
zdump now outputs "UT" when referring to Universal Time, not "UTC".
"UTC" does not make sense for time stamps that predate the introduction
of UTC, whereas "UT", a more-generic term, does. (Thanks to Steve Allen
for clarifying UT vs UTC.)
Data changes affecting behavior of tzselect and similar programs
Country code BQ is now called the more-common name "Caribbean Netherlands"
rather than the more-official "Bonaire, St Eustatius & Saba".
Remove from zone.tab the names America/Montreal, America/Shiprock,
and Antarctica/South_Pole, as they are equivalent to existing
same-country-code zones for post-1970 time stamps. The data for
these names are unchanged, so the names continue to work as before.
Changes affecting code internals
zic -c now runs way faster on 64-bit hosts when given large numbers.
zic now uses vfprintf to avoid allocating and freeing some memory.
tzselect now computes the list of continents from the data,
rather than have it hard-coded.
Minor changes pacify GCC 4.7.3 and GCC 4.8.1.
Changes affecting the build procedure
The 'leapseconds' file is now generated automatically from a
new file 'leap-seconds.list', which is a copy of new file 'leap-seconds.list', which is a copy of
<ftp://time.nist.gov/pub/leap-seconds.list>. <ftp://time.nist.gov/pub/leap-seconds.list>.
A new source file 'leapseconds.awk' implements this. A new source file 'leapseconds.awk' implements this.
The goal is simplification of the future maintenance of 'leapseconds'. The goal is simplification of the future maintenance of 'leapseconds'.
When building the 'posix' or 'right' subdirectories, if the
subdirectory would be a copy of the default subdirectory, it is
now made a symbolic link if that is supported. This saves about
2 MB of file system space.
The links America/Shiprock and Antarctica/South_Pole have been
moved to the 'backward' file. This affects only nondefault builds
that omit 'backward'.
Changes affecting version-control only
.gitignore now ignores 'date'.
Changes affecting documentation and commentary
Changes to the 'tzfile' man page
It now mentions that the binary file format may be extended in
future versions by appending data.
It now refers to the 'zdump' and 'zic' man pages.
Changes to the 'zic' man page
It lists conditions that elicit a warning with '-v'.
It says that the behavior is unspecified when duplicate names
are given, or if the source of one link is the target of another.
Its examples are updated to match the latest data.
The definition of white space has been clarified slightly.
(Thanks to Michael Deckers.)
Changes to the 'Theory' file
There is a new section about the accuracy of the tz database,
describing the many ways that errors can creep in, and
explaining why so many of the pre-1970 time stamps are wrong or
misleading (thanks to Steve Allen, Lester Caine, and Garrett
Wollman for discussions that contributed to this).
The 'Theory' file describes LMT better (this follows a
suggestion by Guy Harris).
It refers to the 2013 edition of POSIX rather than the 2004 edition.
It's mentioned that excluding 'backward' should not affect the
other data, and it suggests at least one zone.tab name per
inhabited country (thanks to Stephen Colebourne).
Some longstanding restrictions on names are documented, e.g.,
'America/New_York' precludes 'America/New_York/Bronx'.
It gives more reasons for the 1970 cutoff.
It now mentions which time_t variants are supported, such as
signed integer time_t. (Thanks to Paul Goyette for reporting
typos in an experimental version of this change.)
(Thanks to Philip Newton for correcting typos in these changes.)
Documentation and commentary is more careful to distinguish UT in
general from UTC in particular. (Thanks to Steve Allen.)
Add a better source for the Zurich 1894 transition.
(Thanks to Pierre-Yves Berger.)
Update shapefile citations in tz-link.htm. (Thanks to Guy Harris.)
