Clocks are not "slow", though they are not synchronous with each other (except
in certain special circumstances, such as when synchronized and at rest in some
inertial frame). In particular, clocks do PROPERLY measure time, when time is
what clocks measure.
In a stunning irony, physicists call this "proper time".
As I have said before, in every experiment that measures time, a clock is used,
so this is the ONLY definition of "time" that makes sense in the context of
experiments -- i.e. in the context of physics.
Your personal a priori notions of what "time ought to be" are completely and
utterly irrelevant. And as I keep saying, actual experiments show that your
notions are WRONG.

Nonsense. You are reading your own INCORRECT notions into Einstein's words. In
relativity, as I repeatedly say, clocks NEVER "run slow". "Time dilation" is NOT
"clocks running slow", it is a variation in geometrical projection, and does not
affect the running (ticking) of ANY clock.
If "time dilation" did affect the ticking of a clock, it's
easy to see that multiple observers looking at a single clock
would require it to "tick at multiple rates" which is manifestly
impossible. Moreover, it ought to be clear that the mere act of
observing a clock cannot possibly affect the clock.
You are just making up nonsense and attributing it to SR and to Einstein. YOUR
PERSONAL MISUNDERSTANDINGS are not SR.

The many measurements of the constancy of the round-trip speed of light, coupled
with the many measurements of the isotropy of the one-way speed of light, all in
various labs on earth (and thus in ever-changing inertial frames). The accuracy
of these measurements is now approaching a million times better than the earth's
orbital speed around the sun, which is a minimal measure of the difference in
these inertial frames.
As I have said many times, a direct measurement of light's one-way
speed has MUCH larger systematic errors than the combination of
measuring its round-trip speed and measuring isotropy of its
one-way speed.

But we have MEASURED that the speed of light is the same in every inertial frame
we have access to, including some moving with speed >0.999 c.
And one can show that clocks in relative motion DO NOT remain in synch, for all
clocks we have access to. We can only use clocks we have access to, which is why
it is impossible.
When you invent some clocks that behaves differently, then you
have a leg to stand upon. Until then, you are just hallucinating.
As I keep saying, you have NEVER described how to achieve
"absolutely synchronous clocks", and you have even refused to
describe what you mean by that phrase.

The problem is with your poor reading skills, not with the clocks. Einstein
NEVER said "they are slowed", because he knew full well that they are not (see
above).

How does your mistake affect Einstein, or what he said????
