You *have* to try/expect in order to not have the script crash.
Think user typo: 21 02 2ß13

Personally, I'd use a javascript on the html so users can't POST invalid  
dates.
I use mootools for that. It accepts 21/02/2013, 21-02-2013 and 21.02.13 as  
input,
and you end up with 21.02.2013 posted to your cgi in any case.
