[AccessD] All-In-One Date format Function:

Hoooooowdy,
 Before re-inventing the wheel here, does anyone have or know of a function
that can handle "free form" date formatting. I'm looking for a function that
can parse any input and then format is correctly. 

Example of user inputs:

0909
09/21/09
09-21-09
092109
92109
9212009

etc.

I don't want to use any formatting / Masking settings at the field or table
level. I would like the user to enter it the way they want to (to the most
degree possible)...

WBR
Robert
