From my "I can't believe they'd make it this way" list.
Last year I purchased a new Westinghouse Model WST-3501 microwave oven for our office lunchroom.
It heats and cooks things fine, but has one lousy feature which I can't avoid noticing and which irks me very time I see it.
The TOD, which is displayed whenever the unit is on standby, loses about two minutes a day, and has to be reset every few days to keep from falling ridiculously behind.
I'm shocked, shocked, that the clock isn't synced to the 120 volt 60 Hz power the unit runs on, like every other line powered appliance with a digital TOD display I own.
The only reason I can guess for the poor timekeeping is that the circuitry/board running the clock is used on their 220 volt 50 Hz versions without modification, so the makers decided not to use line sync for the clock, and probably didn't want to spring for a crystal oscillator either, so used an RC one instead.
I tried emailing Westinghouse about this and they fobbed me off to a subsidiary who couldn't even bother to respond to an email.
Thanks for reading. Anyone got any other ideas about why the stupid clock in this microwave loses time?
