   I think this claim is a bit unrealistic.

But do you agree that Bernstein's library could be used to implement a
version of xtime_get(...,TIME_TAI) that always succeeds, so long as it
never sets the TIME_SYNC bit of the result?  In other words, so long
as xtime_get never _claims_ to be accurate within 1 s, it would
conform to your spec.
