I give up.

You are told the same thing over and over, but either you
don't read it, or you don't understand what you read.

I suspect the latter.
You seem to have a serious reading comprehension problem.

absolutely, good point, I was almost about to mention it, for the 
Einstine, a one without proper skills and education, the term delay wasnt 
into his vocabulary. Even today, it takes long time to realize what a 
propagation delay is. Here more truth, taught in schools about relativity 
in europe

No, but in Einstein's paper.

Actually I can almost sing 'On the Electrodynamics of moving bodies' and 
can assure you, that 'transit delay' or anything similar was neither 
calculated, measured or even mentioned.

Einstein seemingly assumed, that the actual reading of the remote clock 
would be the remote time.

To eleminate this error, you would need to 'ping' the remote station, 
measure the delay for a round trip, cut that in half (supposed the 
remote station is in relative rest) and add this value to your own time.

Then you need to encode the own time plus delay into a signal and send 
that to the remote station.

The remote station would need to decode the signal, extract the time 
value and adjust the own clockks according to that value.

But Einstein didn't say anything like that.

This problem was simply missing entirely in his paper.

The main point is this:

a 'clock' can also be a device, which has no hands and shows time values 
by electronic means. To this value you need to add the delay.

These values need to be encoded somehow into a carrier signal. The 
encoded signal needs to be sent to the remote station, where someone 
decodes it.

The sending station needs to know the delay in advance, hence had to 
measure it by measuring some sort of reflected message.

This is equvalent to a 'ping' on the internet, but can be any kind of 
mechanism.

If you don't do that, your process of synchronization is wrong.

Quote from § 1. Definition of Simultaneity:
  "we establish by definition that the “time” required by light
   to travel from A to B equals the “time” it requires to travel
   from B to A."

"the time required by light to travel from A to B" _is_
the 'transit delay' you say is never mentioned.

Another quote from § 1. Definition of Simultaneity:
  "In accordance with definition the two clocks synchronize if
     tB − tA = t′A − tB."

If the clocks synchronise, then the transit delay for
the pulse is tB − tA = t′A − tB.

The transit delay is _measured_!

So the transit delay is calculated, measured and mentioned.

How did you manage to miss that?
You must have a serious reading comprehension problem!

> 
> Einstein seemingly assumed, that the actual reading of the remote clock

??? Is the clock at B the "remote clock"?

Do you mean that the actual reading of the clock at B
is _not_ the time showed by clock B?

Or what do you mean?

There is no error to correct.

Good Grief! :-D


1. The observer at A reads the time tA when the light pulse
    is sent. He reads the clock at A!

2. The observer at B reads the time tB when the light pulse
    is reflected. He reads the clock at B!

3. The observer at A reads the time t'A when he receives
    the reflected light pulse. He reads the clock at A!

These are all the measurements that are done.
Only local clocks are read.
There is no "reading of the remote clock"!

The observer at A has _measured_ the transit delay.
It is (t'A-tA)/2 ! How did you manage to miss that?

To check if the clock at B is synchronous the observers have
to communicate. They can do it by shouting, send it by snail mail,
E-post, a mobile phone or whatever.
And there is not necessary to encrypt anything!

If they find that their clocks are not synchronous, the clock
at B can be corrected as I explained above,

Quite. Einstein wasn't stupid!

Now you can read my previous post quoted above again.

But with your serious reading comprehension problem,
you will probably not understand it.

Right. All your problems are missing.

There is no problem in his paper.

Moreover Thomas could see this procedure in action at https://noedge.ne/e/ 


He could even check the source code and see Einstein's very equation are 
used to compute the delay to be applied to any of both clocks or both.

Replaying the synchronisation checking procedure allow te see how it is 
reflexive and symmetric.

I may add more clocks to illustrate that the procedure is transitive.

Which all that is needed to dismiss idiotic Hachel's claims btw...
