When you are adding to timestamp without time zone, they *are*
interchangeable, since no daylight-savings arithmetic is involved.
Michael's right for the case of adding to timestamp with time zone,
though.

I agree with that comment --- you should at least think hard
about what you are trying to represent.  The "date" type is also
worth considering if time-of-day isn't so important to you.
