There is a difference between "some" and "this."
All of the clocks here get their time via some network, or from the GPS
constellation.

According to the assembly manual, it uses the power line 60Hz as a frequency
reference. Last I heard, the utilities actually manage the frequency so the
long-term average is very close to 60Hz.
If you want real-time data on power line frequency, check out the FNET
measurement network. It looks like my grid is currently at 59.990.

Some NIXIE clocks use GPS for time, which is good enough for most purposes. :-)

Don't mean to reopen the topic, but what is the accuracy of this clock?
