You point out that you can't even read and understand
a paper with simple math, but you flee from the real challenge
in the post you are responding to.
So please, answer the simple question below:
When the train leaves Nantes, you see the watch on the railway station
showing 8:32, and you start your stop watch. When you arrive in Berlin,
you see the watch on the railway station showing 20:41. You stop your
stop watch which show that the duration of the journey was 12h 9m.
The question:
-------------
Why is the difference between the Berlin clock at arrival and
the Nantes clock at departure equal to the duration of your journey,
  20:41 - 8:32 = 12h 9m ?
You will flee again, won't you?
