Might be need to find one of those GPS disciplined oscillators that put
out 1pps. Then create a circuit to divide by 3600 and fire a 555
one-shot circuit etc.
Pretty neat!

Yeah.  I have a friend who built a driver for the clock based on an old
Rado Shack product "time cube" that was a WWV receiver.  Those are no
longer available either.

I found a cheapish WWV receiver on ebay, but it is totally undocumented
and microprocessor controlled, so I haven't taken time so far to try to
figure out how it works.
