[time-nuts] Personal time keeping...

Well in the old days, when I worked in AM radio, the beep was generated from
a relay across the Western Union clock.

I worked in a couple of stations that did this.  The time hack (at the risk
of bursting anyone's bubble as to accuracy) was based on glancing up at the
control room clock and pushing a button to transmit the tone, all while
creating the impression that it came directly from WWV.
