then assuming both clocks are accurate enough, you can
see any difference in the rate of time you are experiencing vs the other person.

Hi
A GPS receiver is simply picking up the time information from the orbital
system. The satellites
do not change height when you move around, thus their reported time does not
change either.
Coming up with 20 ns from GPS involves a lot of post processing, that’s not
going to play very

I believe not. 20 nS is about 6 meters error in height. I would need to know
the height difference much better than this to have an accurate measurement.

To my simple mind they'd be out but by a constant amount because they're
still locked to one master clock. The discrepancy would be from the "time
of flight" between the top and bottom of the mountain.
Or I may have completely misunderstood.

I have a recording of this on my hard drive, at1.3 Gb it's too big to
email but I can share it via Wetransfer if anyone wants it. I would
need a recipient's email address to do this.

For those of you who missed the live TV broadcast, I'm told PBS has a live
stream:
http://www.pbs.org/video/2365757267/
The cesium clock parts are in the last 15 minutes of the show.
I also added more photos/plots to:

Well, Tom, you did get an active part in the show, and Stephen Hawking
credited your worldwide reputation. Wow.
You even sounded as natural as the actors used to give emotional depth
to a science story.
What troubles me is that we have the instruments to detect a 20

Having not seen it yet, I can't make a promise of its "SNR" (Science to
Nonsense Ratio).
