                <para>The <filename>/etc/localtime</filename> file
                configures the system-wide time zone of the local
                system that is used by applications for presentation
                to the user. It should be an absolute symbolic link
                with a destination of <filename>/usr/share/zoneinfo/</filename>,
                fallowed by a time zone identifier such as
                <literal>Europe/Berlin</literal> or <literal>Etc/UTC</literal>.
                The resulting link should point to the corresponding binary
                <citerefentry><refentrytitle>tzfile</refentrytitle><manvolnum>5</manvolnum></citerefentry>
                time zone data for the configured time zone.</para>

                <para>As the time zone identifier is extracted from the name of
                the target of <filename>/etc/localtime</filename> this file may
                not be a normal file or hardlink.</para>

                <para>The time zone may be overridden for individual
                programs by using the TZ environment variable. See
                <citerefentry><refentrytitle>environ</refentrytitle><manvolnum>7</manvolnum></citerefentry>.</para>
