Date parsing

[Charles P. Killmer]

I have an object with a TimeStamp member.  This will be populated by
users of a website and entered into a database.
 
My problem is, I would like to allow the users to enter the date in a
number of formats.  Does anyone have any recommendations aside from
multiple try catch blocks each trying to parse the given date with a
different expected format?
 
Thanks you for any help,
Charles Killmer
