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 symbolic link
68                 with a destination of <filename>/usr/share/zoneinfo/</filename>,
69                 fallowed by a time zone identifier such as
70                 <literal>Europe/Berlin</literal> or <literal>Etc/UTC</literal>.
71                 The resulting link should point to the corresponding binary
72                 <citerefentry><refentrytitle>tzfile</refentrytitle><manvolnum>5</manvolnum></citerefentry>
73                 time zone data for the configured time zone.</para>
74
75                 <para>As the time zone identifier is extracted from the name of
76                 the target of <filename>/etc/localtime</filename> this file may
77                 not be a normal file or hardlink.</para>
78
79                 <para>The time zone may be overridden for individual
80                 programs by using the TZ environment variable. See
