Yea, most people change the clock.

The only clock I don’t change is my motorcycle because I can’t be bothered to use the archaic menu system to update something I never rely on.

That said, it does take me a few weeks usually to update all the clocks as I’ll only do it when it starts to bother me or if that specific clock contributes to me being late/early.

I run around the house updating every clock I can find early on the Sunday morning. I update the clocks on rental cars if they're wrong. I'm not otherwise a super detail-oriented person. Clearly this is some kind of personality test.
