I just discovered today that customer's can enter dates and times in the date fields on the customer portal that are in the past. For example, they can request a due date that has already passed.
Does anyone know if there is a way to either make it so they can't pick a date/time later than the current time or warn them that they are picking a past date? Also similar is there a way to validate against a date/time, for instance not allow them to enter a due date that's within an hour of the current time?
