The old rubber-ruler problem. I tend not to worry about it too much as long as the equations work out.
I'll posit this -- we calculate for the effects of general relativity (due to altitude) and special relativity (due to velocity) when we communicate with satellites. Now, the interesting fact here is that general relativity (in this case) speeds time up, while special relativity slows it down. If our calcuations weren't correct, we couldn't communicate very effectively with these satellites, as the timings have to be very precise.
All I can do is look to those who have better scientific understanding than I of such matters.
We are talking about basic carpentry tools here.

We aren't talking about levels of reading, we are talking about reading levels as in looking at a simple carpenters tools and understanding why you think it has somthing to say and what it has to say means.

You know, we could send an old Atari 8-bit far enough away that it would be way faster than anything here on Earth -- as far as we're concerned. It'll still be 1.79 MHz (1.77 for the PAL version) in its own frame of reference. It's just that years could go by for it while one second goes by for us.
Needless to say, this sort of strangeness makes it easy for me to reconcile a reportedly young Earth with an apparently old universe.

This sort of idea will never be of any practical use.

True enough. Even as I typed that, I realized we'd never be able to retrieve any results from it (and probably couldn't send it that far away in a reasonable amount of time anyway). It's still an interesting thought experiment, and it might help those having trouble with it to better understand the nature of relativity. So I went ahead and posted it anyway.

There's an easier way to conceptualise the issues.
When we send a satellite into orbit, we know the different gravity environment will affect it's clock. Thus we set it's clock to run at a different rate than our Earth-bound clocks.

We also have to calculate for its orbital velocity. Unless it's geosynchronous, in which case it's always in the same place as far as we're concerned, and therefore shares the same inertial frame of reference.
You and I see the same results -- we're just looking at the equations in a different way. You see time as a constant and C as a variable. I see the opposite. Either way, the end results still work out the same.

Actually, we synchronize it with Earth-bound clocks initially (a second is always a second, wherever one happens to be). When it gets into orbit, we have to re-synch taking time dilation into account.
Good question. I can't think of a way to do it other than comparing your level to another level.
And there in a nut shell is the root of all our various differences mate. (not that our differences have ever caused us not to get along)
You, seem to think that (based on your above statement) Yaweh gave Adam the first level and all levels are calibrated against that level.
But we don't have that level anymore.
I am of a mind that we (mankind) figured out/defined level.
Assumptions play into this and those need to be defined and examined.
But that's what a conversation is all about, right?

Alright, then which second is a real second? The one measured on Earth, or the one measured on the satellite? Why?
Easy. Time isn't constant throughout the universe. It runs at different rates in different places. If the universe has a gravitational center, and we're near it (and these are pretty big ifs, as these notions are generally rejected by most astrophysicists), then due to general relativity time will run by slower here than it will farther away.
