<code>'Mon, 20 Nov 1995 19:12:08 -0500'</code>.  If it succeeds in parsing
the date, <tt class="function">parsedate()</tt> returns a 9-tuple that can be passed
directly to <tt class="function">time.mktime()</tt>; otherwise <code>None</code> will be
returned.  Note that fields 6, 7, and 8 of the result tuple are not
usable.

<dd>
Performs the same function as <tt class="function">parsedate()</tt>, but returns
either <code>None</code> or a 10-tuple; the first 9 elements make up a tuple
that can be passed directly to <tt class="function">time.mktime()</tt>, and the tenth
is the offset of the date's timezone from UTC (which is the official
term for Greenwich Mean Time).  (Note that the sign of the timezone
offset is the opposite of the sign of the <code>time.timezone</code>
variable for the same timezone; the latter variable follows the
POSIX standard while this module follows <a class="rfc" name="rfcref-47409"

  ></a>.)  If the input
string has no timezone, the last element of the tuple returned is
<code>None</code>.  Note that fields 6, 7, and 8 of the result tuple are not
usable.
</dl>

<P>
<dl><dt><b><a name='l2h-2350'><tt class='function'>mktime_tz</tt></a></b> (<var>tuple</var>)
<dd>
Turn a 10-tuple as returned by <tt class="function">parsedate_tz()</tt> into a UTC
timestamp.  It the timezone item in the tuple is <code>None</code>, assume
local time.  Minor deficiency: this first interprets the first 8
elements as a local time and then compensates for the timezone
difference; this may yield a slight error around daylight savings time
switch dates.  Not enough to worry about for common use.
