There used to be a lot of WWV receivers available to pick up time
from the NBS broadcasts, but they seem to have gone away with the
arrival of GPS.
I wrote some software for a wwv receiver about 15 years (on topic
even!), but had to re-write it about 4 years ago when the receiver
died and was replaced with a stationary GPS box. Even pulled
Lat/Long/Alt from the GPS because I could :)
