I have a ~10 year old GE microwave. After using a portable power generator which probably does not have a very accurate frequency, this winter when the grid was out, it seemed to switch itself over to 50Hz, and stayed that way after electricity from the grid was restored.
It was very confusing as the clock consistently ran too fast, and the timer ended before food got as hot as it previously had. I was surprised that something like that would be built into the microwave, and that it would be able to guess something like that. Eventually I unplugged it for a couple hours, and it went back to normal when I plugged it back in.
