[issue47238] Python threading.Event().wait() depends on the system time

[Aleksandr]

New submission from Aleksandr <aleksandr.avferonok at gmail.com>:

This happens on Ubuntu on Python versions 3.8.5 and 3.10.4

I have two threads that can change the system time to a day ago.
If the change in the system time for a day occurs at the time of wait, then I hang for one day plus the waiting time.

I thought Event.wait() uses a monotonous clock, but this behavior points to an absolute clock.

Are there any solutions?
