Ah.  No, we've not talked about doing that, and you don't get to set a
bit on the Date object that says "the time does not matter".  I
suppose you could,  but I don't (yet) know what the consequences are.
For backwards compatibility a date string probably needs to yield a
Date object with a time.  For ISO strings we could conceivably do
something different, but I'm not sure about that.
