Wt

Whenever a user would insert an invalid date or time within a Wt Dbo form, the system would clear the value in fields and as long as the fields aren't required, validation would succeed.

This is due to WDate::toString and WTime::toString returning an empty string by default for invalid WDate/WTime objects. This empty string would then get passed to the validator through the validate functions of WFormModel.

We need to make the Dbo Forms system aware of this so that it can validate the values correctly.
