This part of the copyright blurb stems from the GPL use recommendations: https://www.gnu.org/licenses/gpl-howto.en.html The concept appears to originate in times where version control was per file, instead of per tree, and was a way to glue the files together. Ultimately, we nowadays don't live in that world anymore, and this information is entirely useless anyway, as people are very welcome to copy these files into any projects they like, and they shouldn't have to change bits that are part of our copyright header for that. hence, let's just get rid of this old cruft, and shorten our codebase a bit.

<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>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>
