Can we discover anything useful from existing configure logs? If so, maybe
we can survey the buildfarm database.

Incidentally, use of integer datetimes has been in the default config set
on the buildfarm from day one, because it seems to me far saner, in
principle, to use fixed precision for them, so I cerainly agree with
Neil's goal.
