I've used Time::ParseDate quite a few times. Has an adept parser that handles 
complex stuff and understands time zones. Returns date as seconds since epoch. 
Handy for ebay scripts.

This is a good idea! whenever I want to do something date related, I always 
seem to find a few modules that almost but not quite do what I want, each with 
its own api.
