If the module you're using to do your date arithmetic doesn't allow you to produce a formatted date, you can use the following statement: 
my $date_string = sprintf('%02d%02d%02d', $year-1900, $month, $day);

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
