Hi Lester:
Can you say more about that?
I've got a bunch of WU clocks:

and the one at the top of the above web page is a radio studio clock
with the second hand.
Have Fun,

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.

Is anyone else old enough to remember when you would hear on the radio
"Time at the tone, 5 o'clock. Beep." The tone was anywhere from half a
second to one second long and it might have been hard to pin down if the
beginning or the end of the tone was 5 o'clock but it was probably within
a
couple of seconds accuracy which was plenty good for setting your watch or
the kitchen clock. Why don't you hear that now a days? Digital TV has
latency which is dependant on the equipment used by the cable or satellite
company and is somewhat variable between receiver manufacturers. The
engineer of our local public radio station told me that digital radio has
7
seconds delay. When I asked the station manager if there were any plans
to
run studio time 7 seconds ahead of real time so listeners would get
accurate
time he just frowned.

A number of years back the London Science Museum used to sell an Einstein
Relative Time Watch that just had the hours hand and was marked around
the
dial, 1'ish, 2'ish, 3'ish, etc. I bought my ex one, don't know if she
still
has it. It's not the same as the new ones I have seen via Googling as I
think this was much more fun.

Chuck,
In another post I spoke about spending a few days with a fellow from
DATUM.
A lot of our idle chit-chat was about accuracy in timing and GPS
vs.other
off-air standards and propagation. He told me about his background in
the
military and precision measurements and about a watch he used to have
that
displayed in GPS seconds - fascinating stuffs. I noticed that he wasn't
wearing a watch and I commented on that. He told me that he'd spent a
good
part of his life knowing precisely what time it was and still does the
same
thing in his work at DATUM. He then went on to comment that he was
tired
of
knowing exactly what time it was and he personally got sick of knowing
the
exact time. He also said that looking at the kitchen clock once a day
was
close enough for him, that it reduced the stress on him.

My personal preference is for highly jeweled totally mechanical
automatic winding wristwatches. My hobby compels me to have
high accuracy time and frequency around, but my life just
doesn't run with that kind of precision.
