* Replace "time.clock on windows, or time.time" with time.perf_counter() * profile module: only use time.process_time() instead of trying different functions providing the process time * timeit module: use time.perf_counter() by default, time.time() and time.clock() can still be used using --time and --clock options * pybench program: use time.perf_counter() by default, add support for the new time.process_time() and time.perf_counter() functions, but stay backward compatible. Use also time.get_clock_info() to display information of the timer.
