How To Check A String Has A Valid DATETIME in it?

Thanks for the advice...

I'd really like to check if a string contains a valid DATETIME in my code though. Obviously I'll be presenting the user with an interface that shouldn't allow him to put in an incorrect DATETIME, but you just never know... He may put in 31st September, or something (I hate relying on JS).

There must be some way of doing it!

Any more help would be greatly appreciated.

Thanks...

Matt
