localtime — Local timezone configuration file
/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 "
Etc/UTC". The resulting link should lead to the
timezone data for the configured timezone.
Because the timezone identifier is extracted from the
symlink target name of
file may not be a normal file or hardlink.
/etc/localtime is missing, the
UTC" timezone is used.
The timezone may be overridden for individual programs by
$TZ environment variable. See
