LOCALTIME(5) localtime LOCALTIME(5)


.SH "NAME" localtime - Local timezone configuration file


.SH "SYNOPSIS"


.PP /etc/localtime -> ../usr/share/zoneinfo/...


.SH "DESCRIPTION"


.PP The /etc/localtime file configures the system-wide timezone of the local system that is used by applications for presentation to the user. 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 tzfile(5) timezone data for the configured timezone.


.PP Because the timezone identifier is extracted from the symlink target name of /etc/localtime, this file may not be a normal file or hardlink.


.PP If /etc/localtime is missing, the default UTC timezone is used.


.PP The timezone may be overridden for individual programs by using the $TZ environment variable. See environ(7).


.PP You may use timedatectl(1) to change the settings of this file from the command line during runtime. Use systemd-firstboot(1) to initialize the time zone on mounted (but not booted) system images.
