Every clock I own is on world time, except my car clock.
I remember when these time changes caused me all kinds of problems.
I wear an Apple watch, and use iPhone, and all my computers have Internet access regardless of the OS.
I never even look at the battery powered wall clock in my office, I don't even know if it works, I guess this is a good time to replace the battery and set the hands.
Good times..
There's always an excuse to get all wild and crazy like this.
