Anyway to force 4 digit years

Anyway to force 4 digit years

I have a date field on my input form and in my application settings have chosen the date format to be:
mm/dd/yyyy

If a user inputs 03/15/2009 of course is shows up correctly.
If the user does not follow the convention of mm/dd/yyyy and inputs 3/15/09 the field does not give an error and the date is recorded in the database as 03/15/0009 (notice it does put the "0" in front of the 3, but records the year as 0009).

Is there a fix for this somewhere in the scripting?

Thanks in advance & keep up the great work at Zoho Creator!!!!
