This fails to allow specification to the microsecond level (and note
that with float timestamps even smaller fractions have potential use).
I would suggest dropping the milliseconds argument and instead letting
the seconds arg be float8.  That seems a closer match to the way people
think about the textual representation.

It's not immediately obvious what the default value of "timezone"
will be?
