Simultaneity by PeRi

Simultaneity can be determined by
synchronising clocks, setting two clocks to the same time at location
A and then taking one of them to location B.

How quickly do you plan to move one clock to location B?

If an event occurs at A
at say local time 10.01 hrs and the signal is received at B at local
time 11.01 hrs and if the observer at B knows that the distance AB is
one light-hour and the speed of the signal is c, he could say the
event at A occurred simultaneous with an event that happened one hour
ago at location B.

Yes.  According to the convention you have incompletely described.

Martin,
yes, my OP was incomplete. Regretfully, no one else noticed it. To add
more incompleteness let me add that there are two possible methods to
identify simultaneity (simultaneous events) and one impossible one:

1. Without a clock.
2. With one clock as described in my OP.
3. With two synchronized clocks. This method compares the time of the
stationary clock with the time of the clock that has traveled at a
different speed and then returned to the common location. This method
is illusory because clocks cannot recognize dilated time let alone
accumulate it.
