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 :)

Does anyone have the AT protocol spec for it?
I've always been interested
in the concept of a timekeeper that I could read/set from machines that
were not ethernet/NTP-capable. I've even sat around dreaming up ways to
build a wall clock that was settable and readable either via IR or some
serial connection so I'd have a chance of keeping things sync'ed around here.
If I ever did get an RS-232-based timekeeper, I'd think about throwing it on
a terminal server so everybody else on there could get to it.
I don't know what it's like in your part of the hemisphere, but there's an
atomic clock down in Germany which broadcasts its time. IUt's quite easy to
obtain clocks which rely on its signal, and I've seen designs for a similar
cartridge for the Atari ST. Can't remember whether it plugged into the
parallel or cartridge port.
Hmm, sounds very much like something that would be printed in Elektor or C't.
Anyway, that should be the optimal timekeeping device, assuming you can come
up with the hardware and that you're within reach of the transmitter.
