Right, and it really looks like a lot of the users of POSIX want
it to be right and wish they had an API which would be right, but
it's just not available, partly for this reason.

GPS time is pretty much available, and it is pretty much guaranteed
to remain available so long as there is a technological civilization
around who wants and needs that sort of thing, but it is US DoD only,
not international, not recommended.

TAI is not available, not recommended, and its own agency is openly                                                                                
on the record saying that they might discontinue it.

UTC is available, international, recommended, but dispredictable
because it was designed to serve a dispredictable purpose.

No one thing can serve all these purposes, so is there anything aside
from having two things which are internationally available and 
recommended that would be satisfactory?
