Is there an extension that recognized a user's input of dates in their own format and self-corrected it?

I recall an extension (I think) that I saw a while back that did just this. I’m not sure if it applied to SAEF or just in general - but I do recall it allowed users to input their own custom ways of dates, such as:

• January 6, 2005
• 6 Jan 2005
• Jan 6 2005
• 01/06/2005 (MM/DD/YYYY)
• 01-06-05 (MM-DD-YY)

Anyways, I’m sure you get the idea..
