I can't speak in general, but my digital clock sync.s to the 60Hz (or cps,
if you insist...) when it's available, and reverts to a very crummy battery
powered RC osc. otherwise. (Also, trying to run at ~60 Hz, but not doing
a very good job. Gains about 15 - 20 minutes per hour when runing on backup.)
