More time passed on BGA game timer than real life (many hours!)

[FroggerWimsey]

Has anyone else had more time pass in a BGA game than in real life?
I don't mean figuratively , I mean literally.

I just had a game that I was in positive time (by many hours) jump to showing me more than 14 hours over time! This was in a span of about 8-9 hours, so I am very confused as to how that could happen. Even if I was nearing zero time remaining at ~12:00, it isn't possible to use more than 14 hours before 21:00.

I don't know if this could be relevant, but my BGA anniversary occurred during that same span of time.

Europe switched to summer time (DST) the night from 29th to 30th. It's only 1 hour change, but I'd expect all kinds of glitches.

I think that has to be it.

I also noticed that all of my 'fast' turn-based games had their playing hours shifted by an hour. Very unfortunate.
