As much as I like DJ Bernstein's coding style (the author of libtai), it is
unlikely that TAI64 will be appropriate for our use, since it is also based on
the Olson libraries epoch of 1970-01-01 00:00:10 TAI.

I would prefer a structured variable; separate values for each period of
importace. Since some people have explicitly mentioned wanting to handle deep
prehistory, the thought of subtracting attosecond precision over a range of
billions of years just scares me! Of course, Math::BigInt could handle it...
