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.
