so you don't know what a *unit* stands for in physics and mathematics.
Units *are* to represent the same amount.

again, you don't know what *unit* stands for in physics, math, science
and technology. If not the same, that's *NOT* an unit. Did you see how
big Japan is??

But it does. A second on the GPS master clock at USNO,
which is what GPS time is, is the same as a TAI second,
which is the one and only second there is in physics.

No explanation is needed or possible.
It is just the way things are, by design,

So are you asserting that a clock second is an absolute interval of time?
I don’t think so. I think a clock second in different frame contains a different amount of time
and that’s why a clock accumulated different number of clock seconds when it returns
after a journey.

It appears that you don’t know what a unit is. You think wrongly that a unit of clock time (a clock second ) is an absolute interval of time.

I don't think. That's a convention for that particular *unit*, any
*unit*. Go to wikipedia and come back with what it says. Don't be a fool,
just do it.

JJ, poor halfbrain, TAI second and TAI cllocks are improper
according to your precious physics. That's because TAI time
is observer independent, i.e. absolute.

No, things are exactly opposite. By design. And it's
because they are opposite that your religion had
to ban common sense.

Correctly, an interval of proper time.
(oscilations of cesium atoms and all that)

You understand what that means, I hope?

Jan

PS Invariance under time translations (and hence energy conservation)
is a fundamental postulate of physics.
So yesterday's second will be the same as today's second,
and tomorrow's second will be the same once again.

How can you be sure? TAI definition is an average of some clocks.
If tomorrow an earthquake put one of them a little higher...

No it doesn’t.....that’s why the GPS second is redefined to have 4.4647 periods more of the Cs 133 radiation than the earth second.
