what about swapping the Cs clocks between CERN and LNGS without re-
synchronizing them, and repeating the neutrino test?
Antonio I8IOV
Right, typically when you perform a traveling clock experiment
you don't touch the clocks -- you don't need to synchronize or
resynchronize anything. The key

Tom,
I had to look up traveling clock synchronization to get a
better understanding, and found this link:

The idea that Qz (time on the quartz clock, no?) drops out in
the subtraction
The idea that Qz (time on the quartz clock, no?) drops out in
the subtraction seems to me to require Qz to be invariant.
Hi Bill,
You might be making this more complicated intended. Antonio
was asking about *resynchronizing* clocks.
Here's another example. You're at home at 7:45 AM and see

You get to work at 8:30 AM and notice that your wristwatch is

So far it seemed to me that the overall standpoint of the authoritative time-
nuts list is that the GPS timing and geografical survey of the OPERA experiment
are good (and hence experimental errors or artifacts, if any, should be
searched for elsewhere).

Hi Antonio,
The GPS is very unlikely to give an accurate speed for anything near the
speed of light - for there are many known effects not taken into account
by the GPS protocol.
In the end the OPERA experiment may alert people to the assumptions and
approximations implicit in the GPS.
Antonio,
