News for the tz database
Release 2017c - 2017-10-20 14:49:34 -0700
Briefly:
Northern Cyprus switches from +03 to +02/+03 on 2017-10-29.
Fiji ends DST 2018-01-14, not 2018-01-21.
Namibia switches from +01/+02 to +02 on 2018-04-01.
Sudan switches from +03 to +02 on 2017-11-01.
Tonga likely switches from +13/+14 to +13 on 2017-11-05.
Turks & Caicos switches from -04 to -05/-04 on 2018-11-04.
A new file tzdata.zi now holds a small text copy of all data.
The zic input format has been regularized slightly.
Changes to future time stamps
Northern Cyprus has decided to resume EU rules starting
2017-10-29, thus reinstituting winter time.
Fiji ends DST 2018-01-14 instead of the 2018-01-21 previously
predicted. (Thanks to Dominic Fok.) Adjust future predictions
accordingly.
Namibia will switch from +01 with DST to +02 all year on
2017-09-03 at 02:00. This affects UT offsets starting 2018-04-01
at 02:00. (Thanks to Steffen Thorsen.)
Sudan will switch from +03 to +02 on 2017-11-01. (Thanks to Ahmed
Atyya and Yahia Abdalla.) South Sudan is not switching, so
Africa/Juba is no longer a link to Africa/Khartoum.
Tonga has likely ended its experiment with DST, and will not
adjust its clocks on 2017-11-05. Although Tonga has not announced
whether it will continue to observe DST, the IATA is assuming that
it will not. (Thanks to David Wade.)
Turks & Caicos will switch from -04 all year to -05 with US DST on
2018-03-11 at 03:00. This affects UT offsets starting 2018-11-04
at 02:00. (Thanks to Steffen Thorsen.)
Changes to past time stamps
Namibia switched from +02 to +01 on 1994-03-21, not 1994-04-03.
(Thanks to Arthur David Olson.)
Detroit did not observe DST in 1967.
Use railway time for Asia/Kolkata before 1941, by switching to
Madras local time (UT +052110) in 1870, then to IST (UT +0530) in
1906. Also, treat 1941-2's +0630 as DST, like 1942-5.
Europe/Dublin's 1946 and 1947 fallback transitions occurred at
02:00 standard time, not 02:00 DST. (Thanks to Michael Deckers.)
Pacific/Apia and Pacific/Pago_Pago switched from Antipodean to
American time in 1892, not 1879. (Thanks to Michael Deckers.)
Adjust the 1867 transition in Alaska to better reflect the
historical record, by changing it to occur on 1867-10-18 at 15:30
Sitka time rather than at the start of 1867-10-17 local time.
Although strictly speaking this is accurate only for Sitka,
the rest of Alaska's blanks need to be filled in somehow.
Fix off-by-one errors in UT offsets for Adak and Nome before 1867.
(Thanks to Michael Deckers.)
Add 7 s to the UT offset in Asia/Yangon before 1920.
Changes to zone names
Remove Canada/East-Saskatchewan from the 'backward' file, as it
exceeded the 14-character limit and was an unused misnomer anyway.
Changes to build procedure
To support applications that prefer to read time zone data in text
form, two zic input files tzdata.zi and leapseconds are now
installed by default. The commands 'zic tzdata.zi' and 'zic -L
leapseconds tzdata.zi' can reproduce the tzdata binary files
without and with leap seconds, respectively. To prevent these two
new files from being installed, use 'make TZDATA_TEXT=', and to
suppress leap seconds from the tzdata text installation, use 'make
TZDATA_TEXT=tzdata.zi'.
'make BACKWARD=' now suppresses backward-compatibility names
like 'US/Pacific' that are defined in the 'backward' and
'pacificnew' files.
'make check' now works on systems that lack a UTF-8 locale,
or that lack the nsgmls program. Set UTF8_LOCALE to configure
the name of a UTF-8 locale, if you have one.
Y2K runtime checks are no longer enabled by default. Add
-DDEPRECATE_TWO_DIGIT_YEARS to CFLAGS to enable them, instead of
adding -DNO_RUN_TIME_WARNINGS_ABOUT_YEAR_2000_PROBLEMS_THANK_YOU
to disable them. (New name suggested by Brian Inglis.)
The build procedure for zdump now works on AIX 7.1.
(Problem reported by Kees Dekker.)
Changes to code
zic and the reference runtime now reject multiple leap seconds
within 28 days of each other, or leap seconds before the Epoch.
As a result, support for double leap seconds, which was
obsolescent and undocumented, has been removed. Double leap
seconds were an error in the C89 standard; they have never existed
in civil timekeeping. (Thanks to Robert Elz and Bradley White for
noticing glitches in the code that uncovered this problem.)
zic now warns about use of the obsolescent and undocumented -y
option, and about use of the obsolescent TYPE field of Rule lines.
zic now allows unambiguous abbreviations like "Sa" and "Su" for
weekdays; formerly it rejected them due to a bug. Conversely, zic
no longer considers non-prefixes to be abbreviations; for example,
it no longer accepts "lF" as an abbreviation for "lastFriday".
Also, zic warns about the undocumented usage with a "last-"
prefix, e.g., "last-Fri".
Similarly, zic now accepts the unambiguous abbreviation "L" for
"Link" in ordinary context and for "Leap" in leap-second context.
Conversely, zic no longer accepts non-prefixes such as "La" as
abbreviations for words like "Leap".
zic no longer accepts leap second lines in ordinary input, or
ordinary lines in leap second input. Formerly, zic sometimes
warned about this undocumented usage and handled it incorrectly.
The new macro HAVE_TZNAME governs whether the tzname external
variable is exported, instead of USG_COMPAT. USG_COMPAT now
governs only the external variables "timezone" and "daylight".
This change is needed because the three variables are not in the
same category: although POSIX requires tzname, it specifies the
other two variables as optional. Also, USG_COMPAT is now 1 or 0:
if not defined, the code attempts to guess it from other macros.
localtime.c and difftime.c no longer require stdio.h, and .c files
other than zic.c no longer require sys/wait.h.
zdump.c no longer assumes snprintf. (Reported by Jonathan Leffler.)
Calculation of time_t extrema works around a bug in GCC 4.8.4
(Reported by Stan Shebs and Joseph Myers.)
zic.c no longer mistranslates formats of line numbers in non-English
locales. (Problem reported by Benno Schulenberg.)
Several minor changes have been made to the code to make it a
bit easier to port to MS-Windows and Solaris. (Thanks to Kees
Dekker for reporting the problems.)
Changes to documentation and commentary
The two new files 'theory.html' and 'calendars' contain the
contents of the removed file 'Theory'. The goal is to document
tzdb theory more accessibly.
The zic man page now documents abbreviation rules.
tz-link.htm now covers how to apply tzdata changes to clients.
(Thanks to Jorge Fábregas for the AIX link.) It also mentions MySQL.
The leap-seconds.list URL has been updated to something that is
more reliable for tzdb. (Thanks to Tim Parenti and Brian Inglis.)

Use "MMT" to abbreviate Liberia's time zone before 1972, as "-004430"
is one byte over the POSIX limit. (Problem reported by Derick Rethans.)
Changes to code
The reference localtime implementation now falls back on the
current US daylight-saving transition rules rather than the
1987-2006 rules. This fallback occurs only when (1) the TZ
environment variable's value has a name like "AST4ADT" that asks
for daylight saving time but does not specify the rules, (2) there
is no file by that name, and (3) the TZDEFRULES file cannot be
loaded. (Thanks to Tom Lane.)
