> nothing else in the microwave relies on the time being accurate.
The real question is why does your microwave gives time in the first place. Sounds like they had a display and didn't know what to show on it while the microwave wasn't actively used, I'd say drop the clock altogether
Yeah honestly! But, if I had to guess, it’s probably built into whatever “microwave controller” SOC is mass manufactured.
The clock was an upsell long ago, but now that the whole device is a commodity product, and the clock is using parts already in the machine, I guess it’s just not worth removing.
