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 this +software must be updated separately. For software packages that is installed +via binary packages, they can be upgraded by executing `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. + +# fetch https://security.FreeBSD.org/patches/EN-19:18/tzdata-2019c.patch +# fetch https://security.FreeBSD.org/patches/EN-19:18/tzdata-2019c.patch.asc +# gpg --verify tzdata-2019c.patch.asc + +b) Apply the patch. Execute the following commands as root: + +# cd /usr/src +# patch < /path/to/patch + +c) Recompile the operating system using buildworld and installworld as +described in <URL:https://www.FreeBSD.org/handbook/makeworld.html>. + +Restart all the affected applications and daemons, or reboot the system. + +VI.
