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?
