   The clock at point 'A' should show 'A-time', which is the local time at   
   point A.   
      
   Same with point B and 'B-time'.   
      
   But those time measures are local to A and B (and do not necessary run   
   into the same direction at all possible points).   
      
   That remote location uses the same time, which runs into the same   
   direction and makes clocks tick at the same rate, that is an assumption.   
      
   But this assumption also means, that all clocks in all the universe   
   would run into the same direction and make clocks tick at the same rate.   
      
   THAT is actually 'Newton's absolute time', which is 'external' (kind of   
   'God's clock').   
      
   But if time isn't external, then time had to be restricted to the   
   location in question.   
      
   This would allow the observer at point 'A' (for instance) to declare   
   himself to be at rest and everything else as moving.   
      
   But that observer would need to consider, that all other observers could   
   do the same, but with other time-measures.

   Not delta(t), of course, but time t itself.   
      
   Without some 'absolute time t' you could hardly use delta(t), because   
   that wouldn't make sense, if you have no time t to beginn with.

   Not just because you say so!   
      
   I wanted to show, that a spacetime diagram could be treated as complex   
   valued plain.   
      
   Then time would become imaginary and the real axes real.   
      
   Now we could take the axis of time and rotate it (in our mind only, of   
   course).   
      
   Then another axis would become the new axis of time with new orthogonal   
   real axes of a space, which is also filled with new matter.   
      
   Even if the concept is mathematically very simple, it is totally   
   counter-intuitive.   
      
   BUT: the real world we live in looks like precisely following such a   
   principle.   
      
   In case you don't understand the idea, you could read my 'book', which   
   can be found here:
