It should be an absolute or relative symbolic link pointing to /usr/share/zoneinfo/, followed by a timezone identifier such as Europe/Berlin or Etc/UTC. The resulting link should lead to the corresponding binary tzfile5 timezone data for the configured timezone. Because the timezone identifier is extracted from the symlink target name of /etc/localtime, this file may not be a normal file or hardlink. The timezone may be overridden for individual programs by using the TZ environment variable. See environ7. You may use timedatectl1 to change the settings of this file from the command line during runtime. Use systemd-firstboot1 to initialize the time zone on mounted (but not booted) system images. systemd1, tzset3, localtime3, timedatectl1, systemd-timedated.service8, systemd-firstboot1
