One point to be aware of with TAI, however, is that Unix system clocks
don't normally keep TAI so you can end up with a 20-second differential or
so due to the difference in leap seconds.  Dan's libraries use an external
table to track leap seconds and adjust.  This won't matter for most
applications (the TAI64 formats are independent of whether you're keeping
true TAI or the bastardized Unix UTC-like TAI), but it's something to be
aware of.
