The first of these refactors the json/jsonb timestamp formatting into a
single function, removing a lot of code duplication. The involves
exposing time2tm() and timetz2tm(). I don't think that's a tragedy, so
unless there is any objection I propose to commit it shortly.

The next three expose a bit more of the date/time API. I'm still
reviewing those.

cheers
