In different functions, the multiprocessing module uses the system clock: time.time(). The system clock can be updated manually by the system administrator or automatically by NTP (for example). Attached PR modifies multiprocessing to use time.monotonic() instead to not be affected by system clock changes. time.monotonic() is always available since Python 3.5. See also the PEP 418. |
