Ajas, This is my unconfirmed assertion. You have a validator type of type "date", which returns a string expression of a date object notation. My assertion is that the validator type that you use will give you the data type on the submission in its expressed format.
I changed your code to validate using a regular expression and I received the original data text as regular expression are strings and do not have an alternate expression of their data type. The regex that I used, which may not be eprfect is: (0?[1-9]|1[012])[- /.](0?[1-9]|[12][0-9]|3[01])[- /.](19|20)\d\d Teddy
