I disagree; I think UTC is quite sufficient, and will match the users'
expectations much better.  (executive summary: UTC is the time on your
watch (+/- timezone of course), TAI is behind by a few seconds, and
this difference changes each time there's a new leap second).

However, the reference above is not to TAI, but to a library called
libtai.  I don't know anything about this; Stefan, maybe you could
tell us some more?
