Apparently not. :-/

"Your". ;-)

You can probably assume that they're synced on systems with no more
than one dual-core / hyperthreaded CPU.

My system obviously has two of those.

I'd assume that finding (and, possibly, being unable to correct) TSC skew
is sufficient. Whether it's also necessary (in the mathematical sense ;-)
for the problem to exist is a question somebody else might want to answer
(or not).
