You could use Date | Validate since 10/5/09 10:00 is a valid 'date' while
10/5/09 10.00 is not
The Validation dialog requires you enter start and end date but you can
enter some dummy values if this is unimportant to you

I have created a template which is filled by users for date & time. Since
users are novice, can I force users to enter the cell values only in
dd/mm/yy hh:mm format?
For ex if a user wants to enter 10th May 09 10:00Am & by mistake he types
10/5/09 10.00 ( uses . instead of colon) excel misunderstands.
