Exposing [[DateValue]] as a property does not really scale. What about [[MapData]]? What about private state stored in a closure or a WeakMap?
This can either be done by exposing an object that has the same interface as Date. This could throw on set or it could skip the set methods entirely. If you want instanceof to work then all the methods needs to be overridden.
