localtime - Local timezone configuration file
/etc/localtime -> ../usr/share/zoneinfo/...
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.
Because the timezone identifier is extracted from the symlink target name of
/etc/localtime, this file may not be a normal file or hardlink.
If /etc/localtime is missing, the default "UTC" timezone is used.
The timezone may be overridden for individual programs by using the
$TZ
environment variable. See
environ(7).
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.
