How about :
3. Is it ever appropriate for a DOM API to accept and retain a reference to a Date object?
The timevalue of a Date object that was passed to a DOM API can be modified by the original client after the DOM call returns. If the DOM has retained and uses a reference to the Date object it will see the modified timevalue rather than the originally pass timevalue.
