Personally I think I'd like to reduce our dependence on the C lib.

I think I'd like to see an exception or at least a nil return value
for (e.g.) Feb 29, 2005 or November 31 of any year.

I wonder if this would break any existing code? Probably something
internal in Time/Date/DateTime would break.

Matz? Opinion?
