<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>
|
|
to change the settings of this file from the command line during
|
|
runtime. Use
|
|
<citerefentry><refentrytitle>systemd-firstboot</refentrytitle><manvolnum>1</manvolnum></citerefentry>
|
|
to initialize the time zone on mounted (but not booted) system
|
|
images.</para>
