FreeBSD zoneinfo
contrib
TrueNAS 12.0

Versions Affected : All versions prior to TrueNAS 12.0-U7

Description

Several changes in Daylight Saving Time transition dates happened after previous FreeBSD releases were released affecting many users in different parts of the world.

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. 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.

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.

Mitigation

  • Upgrade to TrueNAS 12.0-U7 or later.
