 "Dr. H." is confusing the issue by bringing up the time delay of a
remote
clock.  In SR, one has observers at every location who records the time
shown on the local clock when a local event occurs.  All the records are
then compared, so speed-of-light time delay is NOT an issue.
 

It is obviously impossible to make two clocks side by side show
the same with infinite precision, there will always be a difference.
For atomic clocks this difference may be less than 1 ns,
for say - wristwatches it will be less than 1 second.

 Which is why "absolute" synchronization is a canard.

There cannot be absolute synchronization.
It is absolutely impossible and abstract because our universe is not made like that.
The notion of a flat and reciprocal plan of present time does not exist.
A completely stupid but unfortunately universal view is to say, today is July 23, and it is July 23 throughout the universe. There is there, on Antares, on Tau Ceti, on Aldebaran, a present moment which is the same as ours, and reciprocally, a sort of plane of present time.
This vision is purely stupid and shows a catastrophic incomprehension by physicists of the nature of space and time.
Now, I'm not saying that we can't do some sort of synchronization, it will be very useful, but perfectly abstract, and based on a synchronization carried out on a single real or abstract point in the universe.
But from this point, synchronization no longer means anything.
This is actually how GPS works by "inventing a plan of present time" based on a point ideally located very far away and equidistant from all the 3D points of our local universe, in a hypothetical and abstract fourth dimension .
It's very useful, of course, and this synchronization is perfect.
But only on this point.
Between them, all the points in the universe where we live are perfectly out of sync.
In short, the present, the plan of present time, in the sense in which we understand it, is pure nonsense.
