Posts expire days early

I know people have reported there’s a bug with the time not matching the expiration, but some of mine expired days, not hours, early.

I have 7 posts all set to expire at 11:59 on November 28 and remove a category. I received an email at 11:59pm on November 15 saying that 4 of them expired at at November 28, 2021 11:59 pm.

I checked the site and one of the four actually did expire and had the category removed.
