Thank you all for confirming my suspicion regarding generators and clocks and for the advice. While i wholeheartedly agree that a 24/7 load like a clock in an off-grid home seems rather foolish, everyone's line between NEED and WANT falls in a different place. I see it as my job to educate and not to judge, as hard as that is sometimes. Though i don't share their views, I still put in systems for those folks believing in "TEOTWAWKI" (the end of the world as we know it). Thanks again, Kris

The local power authority keeps the diesel generators cranked. Hope this help a little. .

Has anyone seen this before? Do clocks use the zero crossing on a 60Hz wave for keeping time and could a frequency discrepency in the generator cause this? My thanks to the brain trust...
