  64                 <para>The <filename>/etc/localtime</filename> file
  65                 configures the system-wide time zone of the local
  66                 system that is used by applications for presentation
  67                 to the user. It should be an absolute or relative
  68                 symbolic link pointing to
  69                 <filename>/usr/share/zoneinfo/</filename>, followed by
  70                 a time zone identifier such as
  71                 <literal>Europe/Berlin</literal> or
  72                 <literal>Etc/UTC</literal>.  The resulting link should
  73                 lead to the corresponding binary
  74                 <citerefentry><refentrytitle>tzfile</refentrytitle><manvolnum>5</manvolnum></citerefentry>
