According to Michael's last report, your patch fails under
--enable-integer-datetimes.
This is an issue where you have to be "as simple as possible, but no
simpler". I think the approach you are proposing is too simple.
Michael's last patch here:

looks considerably more likely to lead to a workable answer.
