How about:
if($time1 > $time2){
$difference = $time1 - $time2;
}else{
die "Invalid date!\n";
}

they are all ready in time format, that is the problem.
Example:
$time1 = Date_to_Time($year,$month,$day, $hour,$min,$sec);
$time2 = Date_to_Time($year,$month,$day, $hour,$min,$sec);
$difference = $time1 - $time2;
> One way: Convert both dates to Perl time() format, then subtract.
