Hope I’m not alone in this - Appliances should only have relative timers.
It only needs to know how to run a program for 30 min, or activate with a delayed start in 5h. Clock time is meaningless for an oven.
Appliance companies, are you listening? Hint: they’re not, circuitry design and manufacture has been outsourced so much they probably don’t even know where they get it from.
Elevators in the office building where I work have screens that run ads, but also have time and date in the corner. It resets every couple of days, so basically every day is in January 1970
