Extra classification points if you can contain it in an hour glass.

Depends on whether you're traceable to NIST...

As much as I believe there should be a place and appropriate recognition
for anyone who has shown dedication to the art of time keeping,
regardless of the technology employed, I remind you of the bylaws of the

I laugthed myself into pieces over that one. ;O)
It needs a thad of update thought, neither HP or Agilent sells these
wrist-
watches anymore, Symmetricom is the manufacture these days.
OK, I fixed the HP link. Thanks.

Well, yes, thanks for asking! I did it a year ago.

Time nuts,
Being a recent addition to the list, I'm going to use my one dumb question*
card on an epistemological
question that's puzzling me.
When you come up with a better measuring device (clock, oscillator, etc.), how
do you know its better?
Since, presumably, the only other tools
Hi!
This weekend I spent a few cycles on making my Wavecrest SIA-3000P more
interactively usefull. The P model has no front display and keyboard, but
hooking up an VGA monitor at the back gave me a picture. The next thing was to
get a mouse working over USB, but I needed a keyboard to press enter
Hi Tom:
Thanks for the lab test report on the earth frequency standard. Since
there are a number of frequency/time standards that have much better
performance I'd like to find a way to directly measure the performance
of the earth standard. I've thought about a telescope looking at stars
or
Mark,
Good question. Here are the rules:
1) If all you have is one clock - then that is the true
time, period.
2) If you have two clocks and they always agree, then
that just means you need better measuring tools.
3) If you have two clocks and a good comparator, then
at least you can tell how

I proposed a platform driven by a synchronous motor referred
to a cesium standard. On this platform is an arrangement to
project an attenuated image of the sun onto a mirror that is
attached to a galvanometer. Light-beam galvos used this kind
of arrangement. The mirror projects the solar
