Python module to extract probable dates from strings?
<p>I'm looking for a Python module that would take an arbitrary block of text, search it for something that looks like a date string, and build a DateTime object out of it.  Something like <a href="http://search.cpan.org/~sartak/Date-Extract-0.03/lib/Date/Extract.pm" rel="nofollow">Date::Extract</a> in Perl</p>

<p>Thank you in advance.</p>
