I have a microwave and oven from the same brand, and their digital clocks diverge about 2minutes in 24h. I just don't understand how it's possible to build a device that poorly in 2020 (they are new) and I also wonder which tech they use for timekeeping. Is it possible that one of them uses a crystal and the other uses the 50Hz? That would explain a small difference.
- eqvinox 6y agoIt's easy enough to mistune a 32768Hz clock crystal by shitty electronics engineering, unfortunately :/ 50Hz might have temporary variations, but it's controlled so that over a longer period of time, you always get the correct number of cycles, e.g. 180000 in an hour. This also means that going off the 50Hz power grid theoretically has better (or even perfect) long-term accuracy. Also means that if you adjusted your clock for this separation event, you'll have to adjust it back :D

- laurent92 6y agoUS current is 60Hz. EU current is 50Hz. Maybe your over maker did some rounding when adjusting by 5/6 and here you go? Btw, does your oven have a 50-60Hz switch?
- kevin_thibedeau 6y agoIt's either a poorly made bottom of the barrel crystal or they cheaped out even further and used a ceramic resonator. That is the price of race to the bottom globalization. Measuring line frequency is a no go because the safety compliance inceases costs.
