Replying to your latest comments including but not limited to:
"It is obviously ridiculous to claim that "time itself" changes
because a clock changes. Clocks used in satellites are always
atomic clocks with precision one to 1E15 or better.
They _never_ change their rate due to change of altitude
or speed or anything else-

That the atomic clocks change with gravity doesn't prove time itself
changes.
For the umpteenth time:
Atomic clocks don't change with gravity.
Nothing affects the rate of a _proper_ clock. It always run at
it's proper rate, advancing one second per second.
"Time dilation" doesn't mean that a clock has changed its rate."
-----------------------------------------------------------------
A reasonable person would acknowledge that the atomic clock's rate can
vary when most other rates do not. Time on the satellite is the distance
traveled divided by the speed. The nuclear clock differs from that until
it is adjusted for the effects of gravity. This has nothing to do with
time itself dilating/contracting. This is correctly regarded as an
instrumental error. The rate of an atomic clock in space provides no
evidence for time dilation. It is a stupid error to equate the reading
on clocks with time.
I said the accuracy is only one issue. My issue was not with the
precision. Please don't put words in my mouth. You couldn't understand
that the atomic cock can function differently while everything else is
unchanged, so time itself is unchanged.
According to the European Space Agency, atomic clocks run faster in
space: "Einstein’s principle details how gravity interferes with time
and space. One of its most interesting manifestations is time dilation
due to gravity. This effect has been proven by comparing clocks at
different altitudes such as on mountains, in valleys and in space.
Clocks at higher altitude show time passes faster with respect to a
clock on the Earth surface as there is less gravity from Earth the
farther you are from our planet." -

Einstein's theories of relativity. First, when two clocks are subjected
to unequal gravitational forces due to their different elevations above
the surface of the Earth, the higher clock—experiencing a smaller
gravitational force—runs faster." -
https://www.nist.gov/news-events/news/2010/09/nist-pair-aluminum-atomic-clocks-reveal-einsteins-relativity-personal-scaleI agree that it is obviously ridiculous to claim time itself changes
because a clock changes. However, the ESA does just this in the above
quote.
You lied when you said, "Atomic clocks don't change with gravity."
You lied when you said, "They _never_ change their rate due to change of
altitude or speed or anything else-"
