localtime(5)
NAME
localtime - Local timezone configuration file
SYNOPSIS
/etc/localtime -> ../usr/share/zoneinfo/...
DESCRIPTION
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.
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.
