 Here is yet another proof of what I am saying, and of the need to re-explain things correctly.

 Do you mean that the fact that Tomas Heger doesn't know what
"invariant" means, is a proof of the need to re-explain
my statement correctly?
 My statement was:
" Richard, read your watch NOW. Write down the time nn:nn:nn.
  The time nn:nn:nn is a proper time (read off a clock), it is
  invariant, not depending on frame of reference.
  Nobody can have another opinion of what time YOU read of YOUR watch."
 Both "proper time" and "invariant" are explained in the text.
 

A piece of paper containing some time value has nothing to do with time, let alone 'proper time', because the value written gets immediatly out of synch with the clock, from which that value was copied.

It is the proper time of the watch at the event of reading it. Nobody
claimed it be useful, just that it is invariont.
