In Perl, you can also use the Date::Manip module:

       4.  The amount of time between two dates.

         $date1 = ParseDate($string1);
         $date2 = ParseDate($string2);
         $delta = DateCalc($date1,$date2,\$err);
           => 0:0:WK:DD:HH:MM:SS   the weeks, days, hours, minutes,
                                   and seconds between the two
         $delta = DateCalc($date1,$date2,\$err,1);
           => YY:MM:WK:DD:HH:MM:SS  the years, months, etc. between
                                    the two
