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.
