That is really the only question, AFAIR. The integer datetimes
implementation on a 32-bit type would have a range of about 1 hour (or
about 1 month, if you reduce it to millisecond precision), which would
make it totally useless.
If we wanted to move toward requiring a 64-bit type, we should put some
big warning into configure now that yells at the user if they don't
have that type. And if no one complains, we can make it a requirement
in a later release.
