sched.scheduler

class sched.scheduler(timefunc=time.monotonic, delayfunc=time.sleep)

The scheduler class defines a generic interface to scheduling events. It needs two functions to actually deal with the “outside world” — timefunc should be callable without arguments, and return a number (the “time”, in any units whatsoever). If time.monotonic is not available, the timefunc default is time.time instead. The delayfunc function should be callable with one argument, compatible with the output of timefunc, and should delay that many time units. delayfunc will also be called with the argument 0 after each event is run to allow other threads an opportunity to run in multi-threaded applications.
