Ok.

But in the case of 'snail mail' the only possible way would be this:

A sends a signal at t_A

B receives a 'ping' at a certain time t_B, which the observer reads from 
his own clock.

He writes that value down and mails the letter to A.

A knows when he had sent out the signal in terms of 'A-time' t_A.

 From the time of arrival of the reflected signal t'_A he can figure out 
the delay and when B should have received the signal in measures of 
'A-time'.

Now A receives the letter from B and reads, what the observer B actually 
measured in terms of 'B-time' of the same event.

A can now figure out the discrepancy between A-time and B-time.

This would enable A to set his clock accordingly, so that it would show 
'B-time' and both clocks are in synch.

But there are two problems with this solution:

1) A couldn't really use a 'B-time-clock' in his environment, which 
based on 'A-time'.

2) Actually he wanted the clock in B to become set to 'A-time'.
