SUBMIT YOUR IDEAI took a slightly different tack from the posted solution (still haven't waded through that RegEx!) -- wanted to be able to handle other likely date formats (e.g., 12-14-58, 9/9/91, January 4, 2001) -- the posted solution won't handle these. Also wanted to allow anyone in the future to convert two digit years to the most likely four digit years even if they use this years from now, so used a DateTimeNow (so if you run this in 2045, 12/14/30 will convert to 2030-12-14).
