So a standard unit of measurement can change value
daily in an unknown fashion and still yield non-arbirtary
results?

You'd have to be able to demonstrate that relativistic effects single
out particular units of measurement to the exclusion of others without
having an effect on the observed phenomena and all within the same
reference frame before being able to substantiate any claim that the
result of a particular measurement is arbitrary. Can you demonstrate
that?

Relativistic effects certainly single out measurements
of time - also length in the direction of velocity.

It has been demonstrated numerous times that the velocity
of a clock affects the length of its second. What is
the velocity of the cesium clock on Earth?

Zero by definition.

Now, that is quite easily proved to be FALSE.

The earth is 25,000 miles in circumference, it makes one revolution a day.

25,000mph/24hrs is over 1,000mph. As you sit there typing you are
traveling over 1,000mph, and so is every cesium clock on earth.

Just as the Earth was the center of the universe by
definition.

Let's ask NASA how they keep the atomic clock on board the space station
in sync with those on earth? Even in synchronous orbit, that space
station has to "race" (travel faster) to keep up ...
