time.clock() does exactly what the docs say: you get access to
a CPU timer. It's normal that CPU timers work differently on
different OSes.

What for ? time.clock() uses the same timer as time.steady() on Windows,
AFAICT, so all you change is the name of the function.

And what's the advantage of that over using time.clock() directly ? |
