'in opposite directions' - So not the same.

Not a 'moving' clock, an 'accelerating' clock - as also for a clock
held up against gravity. It does indeed flow at a different rate, as
has been physically demonstrated without controversy.

The rate of a clock is dependent on its state of absolute motion.
Clocks in relative motion are in different states of absolute motions
and therefore they are running at different rates.

If you measure the distance with a physical ruler instead of light
then you will find the value of TWLS is distance dependent.

OK. Let's analyse the experiment according to the emission theory.

The following is a thought experiment.
It is however based on the results from real 'experiments' which
are performed daily when the UTC clocks are synchronized.
So there is no point in disputing that a real experiment would
show different results from what I state below.
(The required precision is probably not practically attainable, though.)

At equator we have two ground stations which are separated
by 100 km. Station A has a clock, a laser and a light detector.
Station B has a clock, a mirror and a light detector.
The equipment is placed in towers so that they are in plain sight
of each other.
There is no wind, the air is stationary with respect to the ground.

Using the GPS, both clocks are synched to UTC to within 0.1 ns.
----------------------------------------------------------
Are the clocks in synch according to the emission theory, Ralph?
If yes, - are they in 'absolute synch'?
If no, why are they not in synch?

When A's clock shows exactly tA = 0 (00:00:00 UTC) a pulse
is emitted.
The reflected pulse is detected when clock A shows:
tA' = 667.1282 us

At station B, the pulse is reflected off the mirror
and detected by the detector when B's clock shows:
tB = 333.5636 us

The readings of the clocks are compared, and it is found
that tB = (tA + tA')/2 - 0.5 ns

Are the clocks in synch according to the emission theory, Ralph?
If yes, - are they in 'absolute synch'?
If no, why are they not in synch?

Well no. If you separate the two clocks slowly, you can make the
effects of the acceleration negligible. If the two clocks end up
separated but relatively at rest, then they will still be synchronized
in the frame in which they are both at rest. However, they will not be
synchronized in any frame in which they are both moving.

Henri's confusion comes from this scenario:
Take two clocks that are at the same place and both moving together in
some frame. Because they are in the same place, then it is certainly
possible to synchronize those clocks even in this frame in which they
are moving. Now let the clocks slowly separate in this frame, making
the acceleration as small as you like, and bring them to a state where
they are now moving in this frame but separated by some distance.
What, Henri asks, happened so that the clocks are no longer
synchronized?
