I think the time scales we're dealing with here are getting down to the level of accuracy of atomic clocks. How do you verify that the clocks are in fact synchronized closely enough to measure stuff like this? (Answer: Probably by using GPS...)

There are more checks of systematics currently under discussion, one of them could be a synchronisation of the time reference at CERN and Gran Sasso independently from the GPS (Global Positioning System), using possibly a fibre.

And like us, the scientists are each just mathematically temporalized sets of material and personal phenomena. Who curiously attempt to relate to and explain further sets of material phemomena yet wind up stumbling in the conceptual boundaries dividing and nesting in the current incomplete theoretical schemas. Where the limits of sapient sensorium and intelligence begin to factor as speculation evolves, and where wisdom is scarcer than a Higgs event.
