From e4ac94881a81741bb2e9cc4e4fd6071aade2c81e Mon Sep 17 00:00:00 2001 From: Sascha Wildner Date: Sun, 29 Oct 2017 11:46:32 +0100 Subject: [PATCH] Sync zoneinfo database with tzdata2017c from ftp://ftp.iana.org/tz/releases * 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.

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.)
