Well that's good to know. I've considered retrofitting my project
to use the 60 Hz power signal, but the drift isn't really
aggravating enough to do so. I usually only have to reset the time
every couple of months or so when the drift has gotten bad enough
so that the lights come on when it's daylight out or go off in the
morning well before sunrise.
