I realize that it is similar to my previous post however I am
attempting to 'keep things as simple as possible'.

It also provides additional ammunition for resident manure spreaders
to ‘prove’ their superior intellect. They don’t need to thank me.

A person is located on a mountain top and is looking at a (very large)
clock (B) at sea-level.

He notices that clock B is ticking over at a slower rate than his own
clock (A) as theorized by Einstein in general theory and as ratified
by the Wallops Island experiment where a clock at sea-level, being
located in a strong gravitational tidal area, will tick over at a
slower rate than an identical clock on top of a mountain that is in a
weaker gravitational tidal area.

Is he entitled to be of the opinion that if he were to move to sea-
level his clock would be subjected to the same 'law' of physics thus
it will then be ticking over at a slower rate than it is before he
starts his descent?

He moves to sea-level and although his clock's rate of operation (i.e.
it’s ‘proper rate) has seemingly remained unchanged (as has his heart-
beat rate and mental processes which are also affected by his now
being located in a stronger gravitational tidal area) however this
does not alter the fact that he and his clock are now in a stronger
gravitational tidal area than they were on top of the mountain thus
his clock is ticking over at a slower rate than it was before he
descended.

It matters not if the mountaintop observer is looking at this
phenomenon from a ‘minkowskian curved spacetime’ perspective or a
‘euclidian space and time’ point of view; he will see the sea-level
clock ticking over at a slower rate than his own clock.

I think the point others have been trying to make is, how do you
determine if your own clock starts running slower? If you think about
it, the only way to do that is to compare the clock's tick rate
against something else local. But in the present case, this would
reveal nothing, because *everything* local would slow as you descended
from the mountaintop. Since everything local slows, you've got nothing
that would serve as a standard by which you could tell your local
clock is slowing.
