Piling on here. As Louis pointed out, "NSTimestamps are points in time". Messing with that in prototypes is a Bad Idea. You will regret. Have you crossed a DST boundary yet in your testing? And making one database behave differently than others seems at least unwise.
If you want a calendar date, find a different class. Joda Time and Apache Commons would be a good place to start looking. That would make welcome and very useful contribution to Wonder.
