+ <title>Description</title>
+
+ <para>The <filename>/etc/localtime</filename> 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
+ <filename>/usr/share/zoneinfo/</filename>, followed by a timezone
+ identifier such as <literal>Europe/Berlin</literal> or
+ <literal>Etc/UTC</literal>. The resulting link should lead to the
+ corresponding binary
+ <citerefentry project='man-pages'><refentrytitle>tzfile</refentrytitle><manvolnum>5</manvolnum></citerefentry>
+ timezone data for the configured timezone.</para>
+
+ <para>Because the timezone identifier is extracted from the
+ symlink target name of <filename>/etc/localtime</filename>, this
+ file may not be a normal file or hardlink.</para>
+
+ <para>If <filename>/etc/localtime</filename> is missing, the
+ default <literal>UTC</literal> timezone is used.</para>
+
+ <para>The timezone may be overridden for individual programs by
+ using the <varname>$TZ</varname> environment variable. See
+ <citerefentry project='man-pages'><refentrytitle>environ</refentrytitle><manvolnum>7</manvolnum></citerefentry>.</para>

+ <para>You may use
+ <citerefentry><refentrytitle>timedatectl</refentrytitle><manvolnum>1</manvolnum></citerefentry>

+ <citerefentry><refentrytitle>systemd-firstboot</refentrytitle><manvolnum>1</manvolnum></citerefentry>
