It does have a bug from 10:50 - 11:30. If you're in school during these times I can tell you either how to bypass it, or take advantage of it to get extra things done.
If you're in school after 2nd class, you can go room to room until time starts to advance properly again, which should be around 11:30, and then go to PE. Everything will be ok after that.
Or you could take and after the 2nd class, make sure time is advancing 1 minutes at a time (since it doesn't happen every day, just most days) and then go work in the hotel, then go home and take any punishment or random encounter, then go back to school and advance time by going room to room till 11:30, then go to PE normally.
You could go to PE right after the 2nd class when this is happening, but if you do, you will still have to go back to PE after time is progressing normally, and wait until the coach tells you you're late and to go change before you can get back into regular clothes to leave properly.
Never ever ever leave the school for the days end when this event happens before making sure you are back in your school clothes. If it happens, and you didn't shower and change clothes back to school clothes, the next day you come to school you will be in your gym uniform and immediately kicked into the gym area and most of the time won't be able to change clothes until gymn class starts. That will result in fines for missing 2 classes, no homework for 2 class, and have punishment missed, which will get you a massive fine and on the verge of being expelled.
