Stove and microwave have their own clocks with no sync between them, car ‘technically’ automatically updates but I swear for a week straight after the change it will still display the ‘old’ time and then flip back once I start driving. I’ve got a boombox I don’t care what the time says on it and a clock radio at my desk which I do care. But, to your point, even with Standard and Daylight time as it is, I just reset the stove and microwave in about thirty seconds and I’m good the rest of the way. It’s really not that important to me. I get up when it’s dark and go to bed when it’s dark almost any time of the year.
