Don't you find it interesting that the clocks behave as accurately predicted by relativity?
The variation in time corresponds to the calculated value, else the GPS system would not work.
Correct. Because they would be in different frames.
It would seem to me that if two atomic clocks were synchronized on Earth and one were placed on the Moon, they would not stay in sync.
Ah. I think I see what you are getting at. The clock is improperly calibrated as a timekeeping device on Earth but it's just fine for the Moon. Yes time is operating at a different rate on the Moon.
The clock would not disappear into the future or fall into the past just because it's now improperly calibrated for the conditions as a timekeeping device.
Too lazy to look it up even when I give you an exact search term? OK lazy bones:

Tired light? I'm talking about photon interaction with space's zero point energy. Surely you are not suggesting that photon interaction laws conveniently ceases when one looks up at distant galaxies?
Tired light is a class of hypothetical redshift mechanisms that was proposed as an alternative explanation for the redshift-distance relationship.
So you're not denying the redshift, you're saying it's not caused by a "rush-away-from-each-other movement" or more correctly the "metric expansion of space" as others have pointed out, but by something else, and even if you don't realize it, your hypothesis is a form of a "tired light" hypothesis and you're not the first to think of it, it's an idea which has been explored thoroughly, with some of the main contradictions to observation noted here:
I also say, "redshift from other galaxies is not caused by general rush-away-from-each-other movement...
And the translation of "degrade a photon's energy" for you non technical folks, is "cause redshift". That's just the first on the list. I suggest you read the whole list of problems with the idea.
There is no known interaction that can degrade a photon's energy without also changing its momentum, which leads to a blurring of distant objects which is not observed. The Compton shift in particular does not work.
If I understand why you think there is a difference maybe I can explain better...but I don't understand why you think there's a difference between timekeeping and time in this case. Please explain. How could you determine if there was a difference?

Yes time is operating at a different rate on the Moon.
You mean if you were timing it with a clock on the Moon? I'm not sure. You'd have to take the orbital velocity of the Moon into account as well as the reduced gravity. But unless it balanced out just right, it wouldn't be 24 hours. But whatever it was it wouldn't amount to much difference.
If you were on the Moon watching the Earth rotate, how long would it take to see one full rotation?
One orbit per one rotation of Earth, yes. The flow of time isn't really relevant. It's orbital mechanics that synchronizes them, not time.
How does it work with a geosynchronous satellite? Regardless of how it's calibrated, it's still going to make one revolution per day with respect to the stars isn't it?

great thread too many attackers though

Timekeeping is only as accurate as the device keeping the time.
I view one year as real. If an atomic clock were calibrated to sync with a clock that remained on Earth and then suspended at 100,000 feet for one year, the clock was suspended for one year regardless of what the inaccurate display reports. Does this help? I really want to know about this.
Yes I think it helps. In relativistic terms, what you seem to be saying is that your reference frame is the preferred one. According to relativity, there is no preferred reference frame.

Ready? Okay. I'll form the opposition to root concepts (particle existence, observation of dark energy) - just to see how strong they are.
I, as the oppostion, say, "quarks don't exist". Prove me wrong.
I also say, "redshift from other galaxies is not caused by general rush-away-from-each-other movement, as many galaxies actually move towards one another and even collide. Instead, redshift is caused by photon interaction with space itself". Prove me wrong.
I finally say, "if virtual particles exists even in total vacuum, how come the CERN is never picking them up? " Prove to me quantum model is the right one.

Meaning my time dialated and slowed my time relative only to me down.
Also time dialatikn is real and exactly measured in relation to gravity and velocity, it is even used by us todY, google gps and how it works, this will provide a better explanation than I probably can, I am not a very patient or apt teacher, I am the doing type.
That would depend upon what you base your logic. Basing it on personal experience is not valid in this case.
So, what would be the most logical explanation for the difference in the time shown on our onboard clock as opposed to the clocks just outside our rocket?
The "energy" that runs the clock is the frequency of vibration of atoms. That doesn't change a whole lot. But using your logic, why does a clock run faster when it is in orbit than it does on Earth surface? But when brought back to Earth it runs at the "normal" rate?
That we altered time itself, or that the speed of the ship slowed down the energy that runs our onboard clock, along with the atoms that make up us and everything on the rocket?
