Switching from UTC to TAI opens up a whole new can of worms.  In particular:
1) AFAIK, civil time is derived from UTC.
2) It is not possible to accurately convert a future time between TAI and
   UTC (because the offset between TAI and UTC depends on the _measured_
   decay in the Earth's rotation).

That said, when we do move to a 64-bit time_t, TAI64 would be a reasonable
choice.
