python3-freezegun 1.2.1+actually1.2.1-1 (amd64 binary) in ubuntu lunar

 FreezeGun allows easy mocking of the datetime module by freezing the return
 value of the methods datetime.datetime.now(), datetime.datetime.utcnow(),
 datetime.date.today(), and time.time() to a fixed point in time. Use it
 in unit testing to make the tests deterministic and time-independent.
