Date Comparison and Manipulation Functions?

[W. eWatson]

Are there some date and time comparison functions that would compare, say,

Is 10/05/05 later than 09/22/02?  (or 02/09/22 format, yy/mm/dd)
Is 02/11/07 the same as 02/11/07?

Is 14:05:18 after 22:02:51? (24 hour day is fine)

How about the date after 02/28/04 is 02/29/04, or the date after 09/30/08 is 
10/01/08?

How about is 03/03/04 20:10:08 after 03/07/03 14:00:00? Probably the others 
above will suffice.
