Older people always remind me to change my clocks for Daylight Saving Time.
I haven't used a clock in years that I need to manually reset. Older people don't seem to realize clocks on phones and other devices reset automatically.

Had to reset the clock on my stove, microwave, coffee maker, and cars.
It’s no where near obsolete as you seem to imply.
My stove did need setting, but my 84 yo father in law’s car did set itself.
Stove, microwave, and two battery-operated dial clocks here. I didn't go anywhere today, so I'll find out in the morning if the car needs it. I honestly don't remember. The Rice cooker just cycled back to correct. :-)
Here in germany i think there's a radio signal being transmitted on a dedicated frequency that does nothing but distribute the current time information to digital devices. It's really useful!
It's everywhere, but not all devices have the radio
That's existed since at least the 60's, maybe even earlier.
And electric clocks used to get their timing from the frequency of the electrical system, and power companies would compensate for any daily variations by changing the frequency over night so any timing systems would be back in sync.
Commercial buildings often used these kinds of clocks.
Are you sure you're talking about the same thing as me? Sounds like devices use the 50/60 Hz grid frequency instead of an internal resonator/frequency generator to count forward the seconds. But it doesn't tell the device "what time is it now" when you first switch it on.
Huh. That does sound pretty damn useful.

Id never even heard of it in Canada.
Most of us don't bother with that. The only clock I manually change is the one on my car. The other appliances are always blinking 00:00 from whenever the last power outage was.
I will say that it's useful having an always visible clock in the kitchen when cooking. For me that's the microwave.
Technically it doesn't need to be accurate, though, because it's for time differences (boil for 10 minutes, etc)
Mostly all of those too, except my cars. My cars grab their time info from GPS and update automatically. Have for the past few cars I’ve had, but they’ve all been German.
