      Most of the date and time results are dependent on the time zone

      The regression test driver sets environment variable
      <envar>PGTZ</envar> to <literal>PST8PDT</literal>, which normally
-     ensures proper results.  However, your operating system must provide
-     support for the <literal>PST8PDT</literal> time zone, or the time zone-dependent
-     tests will fail. To verify that your machine does have this
-     support, type the following:
-<screen>
-env TZ=PST8PDT date
-</screen>
-     The command above should have returned the current system time in
-     the <literal>PST8PDT</literal> time zone. If the <literal>PST8PDT</literal> time zone is not available,
-     then your system may have returned the time in UTC. If the
-     <literal>PST8PDT</literal> time zone is missing, you can set the time zone
-     rules explicitly:
-<programlisting>
-PGTZ='PST8PDT7,M04.01.0,M10.05.03'; export PGTZ
-</programlisting>

-     There appear to be some systems that do not accept the
-     recommended syntax for explicitly setting the local time zone
-     rules; you may need to use a different <envar>PGTZ</envar>
-     setting on such machines.

-     Some systems using older time-zone libraries fail to apply
-     daylight-saving corrections to dates before 1970, causing
-     pre-1970 <acronym>PDT</acronym> times to be displayed in <acronym>PST</acronym> instead.  This will
-     result in localized differences in the test results.
