We arrive at a much more practical determination along the following line
of
thought.
If at the point A of space there is a clock, an observer at A can
determine the
time values of events in the immediate proximity of A by finding the
positions
of the hands which are simultaneous with these events. If there is at the
point B
of space another clock in all respects resembling the one at A, it is
possible for
an observer at B to determine the time values of events in the immediate
neigh-
bourhood of B. But it is not possible without further assumption to
compare,
in respect of time, an event at A with an event at B. We have so far
defined
only an “A time” and a “B time.” We have not defined a common
“time” for
A and B, for the latter cannot be defined at all unless we establish by
definition
that the “time” required by light to travel from A to B equals the
“time” it
requires to travel from B to A. Let a ray of light start at the “A
time” tA from
A towards B, let it at the “B time” tB be reflected at B in the
direction of A,
and arrive again at A at the “A time” t
.
In accordance with definition the two clocks synchronize if
tB − tA = tA − tB.

I don't understand anything this man is saying.
Is it me who's a moron or him who was incompetent and didn't understand
anything at all?
