I think this discussion has veered off a bit into the overly-theoretical.  Python cannot really "guarantee" anything here; alternately, it guarantees everything, since if you don't like what Python gives you you can always get your money back :).  It's the OS's job to guarantee things.  We can all agree that a monotonic clock of some sort is useful.

However, maybe my application wants CLOCK_MONOTONIC and maybe it wants CLOCK_MONOTONIC_RAW.  Sometimes I want GetTickCount64 and sometimes I want QueryUnbiasedInterruptTime.  While these distinctions are probably useless to most applications, they may be of interest to some, and Python really shouldn't make it unduly difficult to get at them.
