Date::Parse is a little weak at recognising European dates:

I include this code in lib/ and it seems to work ok:

elsif ($args{'Format'} =~ /^unknown$/i) {
    require Date::Parse;
    require POSIX;
    #Convert it to an ISO format string

    my $date = Date::Parse::str2time($args{'Value'});

New from here

    # Major bug in that it doesn't recognise European Dates. Perhaps a

new version of Date::Parse works better? Slow connection, so no time to find
# if date is still undef, assume format mm/dd/yy[yy]
if($date eq undef) {
my ($chewy_d, $chewy_m, $chewy_y);
($chewy_d, $chewy_m, $chewy_y) = split(///, $args{‘Value’});
$chewy_y = int($chewy_y);
$chewy_m = int($chewy_m);
$chewy_d = int($chewy_d);
if($chewy_y > 2000) { $chewy_y -= 1900; }
elsif($chewy_y < 100) { $chewy_y += 100 };
$date = POSIX::mktime(0, 0, 17, $chewy_d, ($chewy_m - 1),
$RT::Logger->debug("RT::Date used Chewy’s mechanism to make
($chewy_d, $chewy_m, $chewy_y) “. $args{‘Value’} . " $date\n”);

To here

    #This date has now been set to a date in the _local_ timezone.
    #since ISO dates are known to be in GMT (for RT's purposes);

    $RT::Logger->debug("RT::Date used date::parse to make

“.$args{‘Value’} . " $date\n”);
