 We can't synchronize all the watches in our 3D universe.

 This is nevertheless done (in ECI frame of reference when it
comes to GPS, or in Earth frame for airports as Paul tried,
in vain, to explain to you).

Since Oslo is 8 degrees east of Paris, UTC clocks in Oslo
and Paris are not absolute synchronous in the ground frame,
because the ground is moving in the ECI-frame.
But the difference is so minute that the clocks are synchronous
in the ground frame _within 1 second_.
I saw no reason to explain this to Richard.
