.IX Subsection "is_valid"
This Input Handler verifies that it is dealing with a reasonable
date. Reasonably means anything that Date::Manip thinks is
sensible, so you could use any of (for example):
  \*(L"December 12, 2001\*(R"
  \*(L"12th December, 2001\*(R"
  \*(L"2001\-12\-12\*(R"
  \*(L"next Tuesday\*(R"
  \*(L"third Wednesday in March\*(R"
.PP
See Date::Manip for much more information on what date formats are
acceptable.
.PP
The resulting date will be a Date::Simple object. 
Date::Simple for more information on this.
.SS "date_format"
.IX Subsection "date_format"
By default ambiguous dates of the format 08/09/2001 will be treated as
\&\s-1UK\s0 style (i.e. 8th September rather than 9th August)
.PP
If you want to change this, subclass it and override \fBdate_format()\fR
.SH "WARNING"
.IX Header "WARNING"
Date::Manip does not play nicely with taint mode. In order to work
around this we locally clobber Date::Manip's 'timezone' code. As we're
only interested in dates rather than times, this shouldn't be much of
an issue. If it is, then please let me know!
