gaining time
« on: July 11, 2005, 11:59:50 PM »
I plugged in a digital clock-radio into my solar powered back up system 12v to 120ac during a power outtage and the clock gained time like crazy. Whats up?

Your clock uses the system frequency to count time. That is 60 cycles per second for USA. Your back up system must have been running at a high frequency 65 Hz for example.

All winter long, the clock on my kitchen range ran fast. Now it's summer and the clock runs slow. Not exactly what I would have guessed for a changing clock speed in my Xantrex 3000 plus, which sits in an insulated compartment outdoors. When I build my perfect inverter, one priority will be a stable clock speed. --tom

Maybe the cooktop clock just likes summer more than winter. I live in the atlanta area and my power goes off quiet frequently and all these clocks have to be reset

a big mennice. I like the battery power ones they run about 2 years before I have to change batteries. I also agree that the frequency is greater than 60 hz causing the faster speed.
