You claim that clocks in Norway and France are not synchronous
even if both show the time UTC + 2h because of the universal
anisochrony.

The question is about your anisochrony, so please read this and
answer the questions.

I leave Oslo Airport (Gardemoen Airport) when the watch on the airport
shows 12.00.00
I arrive at Paris Airport (Charles De Gaulle Airport) when the watch
on the airport shows 13.30.32.

The difference is T = 1h 30m 32s
Is this a real time, or is it impossible to know the real time
because of the universal anisochrony?

The distance in the ground frame between the airports is L = 1358.03 km.
Is the real speed of the plane in the ground frame v = L/T = 900 km/h,
or is it impossible to know the real speed of the plane because
of the universal anisochrony?


The question is simple:
Is it possible to calculate the real duration of the journey
by comparing the reading of the clock in Oslo at the departure
and the reading of the clock in Paris at arrival?

Yes or no, please.

I can understand why you find it very hard to answer
questions when they are taken from practical scenarios
in the real world, and not from your fantasy world.
