Sorry to put you on the spot rick, but which ones don't?
I thought most modern databases use a floating point to store datetimes with
the non-decimal part denoting the day and decimal part denoting the time.

A few bytes possibly, not enough to make it worthwhile.
In fact I would assert that a text format:
Soccer_kickoff@=2005-02-28 T 11:30 AM -10:00
is pretty compact and succinct.
28 bytes of date/time text compared to 8 bytes in a binary format but with
no readability. I don't think that is too bad.
but times are not as often transmitted as dates.
balance_payable@=2005-03-15
In most business data transfer systems, I think dates get transferred a lot
more than times. But obviously, having a field type that does both is a
fairly trivial thing.
