Doesn't work as expected when combined with pytest-freezegun.

To test the code that uses schedule, I ran the following test code in combination with freezegun, but the test failed.

def test_time(freezer):                                                                                                                                  
    import schedule

pytest-freezegun appears to be freezing the time as intended. What could be the issue?

[kimata]

Note that up until version 1.2.1, I could force the test to pass by modifying freeze_time as shown below. However, since version 1.2.2, it takes time zones into consideration, so it is no longer possible to pass the test.

    freeze_time = datetime.datetime.now(tz=datetime.timezone(datetime.timedelta(hours=9))).replace(                                                            
        hour=0, minute=0, second=0                                                                                                                             
    ) + datetime.timedelta(hours=+9)

It may be problem of schedule. So, I close this issue.
