   That is, again, your assertion and you have not provided any proof of that.   
   You may think your assertion is logical, but physics is not based in logic   
   but in building models and test them by experiments.   
      
   The different elapsed times are due to the geometry of the movements of the   
   clocks. They follow different paths, which each clock travels at exactly   
   1 sec/sec. Since the paths are different, it follows that the amount of time   
   between the start and the end of the experiment will indeed differ.   
      
   Again, this is quite similar to why two identical odometers, in two identical   
   cars, show different distances between Chicago and New York, because they   
   followed different paths between these two cities. The difference is due to the   
   geometry of the problem.   
      
   You recognize that you are not interested in going into the equations that   
   show this geometry, because you are not familiar with any math regarding this   
   problem. Proceeding in that way, it will get too difficult to you to understand   
   any of the basics of Special or General Relativity.
