No, it does not, according to special relativity. This may seem somewhat bizarre, but infact the cardinal ordering of events doesn't necessarily remain the same, unless there is some causality link between them. In the case of a car crash in London and one in New York, the ordering of these events may depend on your frame of reference:

I see a distinction without a difference. I don't think time is something that CAN be.measured. The passing of time is all we can measure. An improperly calibrated clock does not indicate a change in time anymore than turning a clock back is time travel.
It's not "time" that's changing, it's the "passage of time" that is changing.

In what way is the passage of time changing? Can you give an example to help me understand exactly what you're saying?

DenyObfuscation was asking if different time measurement (say in GPS satellites was one topic) could be a measurement issue due to the calibration of the clocks. I have been trying to explain that it's not a measurement issue, but time is actually slower on the Earth clocks than in the GPS clocks, yet the above statement by you seems to contradict what I've been saying. So I wouldn't use the word "enemy", but you have chosen to express a distinction contrary to my claim there isn't one. I can hardly say you're agreeing with me when you say something that's the opposite of the point I've been trying to make, and there was already enough confusion about this already.
Time doesn't change, the perception of (or measurement of) time can vary
Sounds like good advice. It's not unreasonable for us to suppose your comments are made in the context of the ongoing discussion.

Holy cow, we have done went and did it now, you are a scary fast learner. And correct, very nice.

In a series of experiments described in the September 24 issue of Science, researchers at the National Institute of Standards and Technology (NIST) in Boulder, Colo., registered differences in the passage of time between two high-precision optical atomic clocks when one was elevated by just a third of a meter or when one was set in motion at speeds of less than 10 meters per second.
The clocks are not mechanical. The prelaunch adjustments made to them are accurate because the calculations used rely on relativity. If other effects were at play the accuracy would not be as high as it is.
My belief is they are affected mechanically
Yes.
Then I sincerely ask, were these clocks in a different frame of reference from each other?
Yes.
It seems reasonable to me that launching these clocks into orbit is just an exaggeration of this effect.

Sure, just as Phage stated with the light entering the black hole, the light doesn't speed up, the measurement of the light changes, it changes in wavelength. The passage of the light changes, not the amount of energy, just the measurement of it.

Frankly I don't understand the distinction you're trying to make between time, the passage of time, and the measurement of time using atomic clocks in ANY context.

Too bad it doesn't help you solve time dilation issues. The rate of time passing really does change. Ask a muon.
