Convert the dates to seconds (i.e. however many millions of seconds 
since the Unix epoch began on 1 Jan 1970), then do the arithmatic on the 
two numbers you get, then convert the result to a more familiar format.

This is a FAQ -- if this description doesn't make clear how to do it, 
there's plenty of code out there that will show you how it works.
