Every appliance in my house (with a clock anyway) and all of our clocks (2 analog, 2 digital) require manual changing. None of them are connected to the internet, which I would think is the only way they would be able to. Do they really make "smart" analog clocks now?
Edit: my car is somewhere in between. It'll "automatically" change, but I have to turn it on/off. It's basically just automated the action of moving the hour forward or back.
Ah, I forgot Atomic (radio) clocks existed. My parents used to have one of those over a decade ago, but I always saw them as more of a novelty. Not saying they're not valid, just uncommon IMO.
