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 \fBtzfile\fR(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 \fI$TZ\fR environment variable\&. See \fBenviron\fR(7)\&. .PP You may use \fBtimedatectl\fR(1) to change the settings of this file from the command line during runtime\&. Use \fBsystemd-firstboot\fR(1) to initialize the time zone on mounted (but not booted) system images\&. .SH "SEE ALSO" .PP \fBsystemd\fR(1), \fBtzset\fR(3), \fBlocaltime\fR(3), \fBtimedatectl\fR(1), \fBsystemd-timedated.service\fR(8), \fBsystemd-firstboot\fR(1)
