Zbigniew Jędrzejewski-Szmek 11a1589223 tree-wide: drop license boilerplate
Files which are installed as-is (any .service and other unit files, .conf
files, .policy files, etc), are left as is. My assumption is that SPDX
identifiers are not yet that well known, so it's better to retain the
extended header to avoid any doubt.

I also kept any copyright lines. We can probably remove them, but it'd nice to
obtain explicit acks from all involved authors before doing that.

<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>
