Sure.

But I use this setting, anyhow.>

No, because Einstein wrote about a method, which included clocks.

But clocks are technical devices and are subject to human interactions.

Time in contrast is not supposed to be affected by humans or clocks.

So, Einstein's definition does not define time, but describes a 
technical method, which ultimatively synchronizes remote clocks.

(And as an enignieer I know a few things about technical procedures.)

If Einstein actually wanted to define simultineity he should have use a 
hypothetical signal, which connects without delay.

That such a signal does not exist in reality does not hinder to define 
it and use it in a definition.

The discrepancy to the real world  and the real signal by light or radio 
waves could be put in 'by hand' and by calculating the delay of light to 
travgel between two points and adding the result to the timing signals.

Really? Could he do that?

Well, yes.

This is similar to a proof in mathematics.

The mirror was supposed to stand near the clock at point B, while the 
observer at A sends out a beam of light at some known point in time.

So, the observer at B (also named 'B') watches his mirror and tries to 
catch that moment, when a signal from A arrives, looks immediatly at his 
watch and tries to remember, where the hands were.

But what Einstein didn't write was also important:

he had to write down the read out of his clock and mail it to A.


Ok, actually that method was the other way round:

A reads out his clock at the start of the ray, writes that value down

next A reads the own clock, once the ray returns and writes that value down.

Then this paper is sent as a letter (by US-postal service or similar) to 
the remote station (the Moon for instance).

There the observer at B receives the letter, calculates the delay, adds 
that delay to the start time and turns the own clock to the result.

Well, but I could.

So lets assume 'Alpha Centaury'.


the only problem:

Us postal has no office there.
