Background + +The tzsetup(8) program allows the user to specify the default local +timezone. Based on the selected timezone, tzsetup(8) copies one of the +files from /usr/share/zoneinfo to /etc/localtime. This file actually +controls the conversion. + +II. Problem Description + +Several changes in Daylight Savings Time happened after previous +FreeBSD releases were released that would affect many people who +live in different countries. Because of these changes, the data in +the zoneinfo files need to be updated, and if the local timezone on +the running system is affected, tzsetup(8) needs to be run so the +/etc/localtime is updated. + +III. Impact + +An incorrect time will be displayed on a system configured to use one +of the affected timezones if the /usr/share/zoneinfo and /etc/localtime +files are not updated, and all applications on the system that rely on +the system time, such as cron(8) and syslog(8), will be affected. + +IV. Workaround + +The system administrator can install an updated timezone database from +the misc/zoneinfo port and run tzsetup(8) to get the timezone database +corrected. + +Applications that store and display times in Coordinated Universal Time +(UTC) are not affected. + +V. Solution + +Please note that some third party software, for instance PHP, Ruby, +Java and Perl, may be using different zoneinfo data source, in such +cases these software has to be updated separately. For software +packages that is installed via package collection, they can be +upgraded by doing a `pkg upgrade'. + +Following the instructions in this Errata Notice will update all of +the zoneinfo files to be the same as what was released with FreeBSD +release. + +Perform one of the following: + +1) Upgrade your system to a supported FreeBSD stable or release / security +branch (releng) dated after the correction date. Restart all the affected +applications and daemons, or reboot the system. + +2) To update your system via a binary patch: + +Systems running a RELEASE version of FreeBSD on the i386 or amd64 +platforms can be updated via the freebsd-update(8) utility: + +# freebsd-update fetch +# freebsd-update install + +Restart all the affected applications and daemons, or reboot the system. + +3) To update your system via a source code patch: + +The following patches have been verified to apply to the applicable +FreeBSD release branches. + +a) Download the relevant patch from the location below, and verify the +detached PGP signature using your PGP utility. + +[FreeBSD 11.1] +# fetch https://security.FreeBSD.org/patches/EN-17:09/tzdata-11.1.patch +# fetch https://security.FreeBSD.org/patches/EN-17:09/tzdata-11.1.patch.asc +# gpg --verify tzdata-11.1.patch.asc + +[FreeBSD 11.0] +# fetch https://security.FreeBSD.org/patches/EN-17:09/tzdata-11.0.patch +# fetch https://security.FreeBSD.org/patches/EN-17:09/tzdata-11.0.patch.asc +# gpg --verify tzdata-11.0.patch.asc + +[FreeBSD 10.4] +# fetch https://security.FreeBSD.org/patches/EN-17:09/tzdata-10.4.patch +# fetch https://security.FreeBSD.org/patches/EN-17:09/tzdata-10.4.patch.asc +# gpg --verify tzdata-10.4.patch.asc + +[FreeBSD 10.3] +# fetch https://security.FreeBSD.org/patches/EN-17:09/tzdata-10.3.patch +# fetch https://security.FreeBSD.org/patches/EN-17:09/tzdata-10.3.patch.asc +# gpg --verify tzdata-10.3.patch.asc + +b) Apply the patch.

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.) ++ ++Release 2017b - 2017-03-17 07:30:38 -0700 ++ ++ Briefly: Haiti has resumed DST. ++ ++ Changes to past and future time stamps ++ ++ Haiti resumed observance of DST in 2017.

(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.) ++ ++ ++Release 2017a - 2017-02-28 00:05:36 -0800 ++ ++ Briefly: Southern Chile moves from -04/-03 to -03, and Mongolia ++ discontinues DST. ++ ++ Changes to future time stamps ++ ++ Mongolia no longer observes DST.

This also affects Antarctica/Palmer. ++ ++ Changes to past time stamps ++ ++ Fix many entries for historical time stamps for Europe/Madrid ++ before 1979, to agree with tables compiled by Pere Planesas of the ++ National Astronomical Observatory of Spain. As a side effect, ++ this changes some time stamps for Africa/Ceuta before 1929, which ++ are probably guesswork anyway.
