2. Those who think that "monotonic clock" means a clock that never jumps, and that runs at a rate approximating the rate of real time. This is a very useful kind of clock to have! It is what C++ now calls a "steady clock". It is what all the major operating systems provide. All clocks run at a rate approximating the rate of real time. That is very close to the definition of the word "clock" in this context. All clocks have flaws in that approximation, and really those flaws are the whole point of access to distinct clock APIs. Different applications can cope with different flaws.
I think that this is incorrect.
py> time.clock(); time.sleep(10); time.clock() 0.41 0.41
