Well, thanks for throwing a monkey wrench into it for me. How do the
famous de-synchronized clocks fit into this? Obviously one of them slowed
down relative to the other. Do we infer that the ground-based clock
decelerated sufficiently to speed up time's local passage? I thought I had
a handle on this, but now I see I'm missing something.

Hmm. This is the part that always messes me up. So if there is a distant
star whose light we see as red-shifted, and X is standing on Earth, while Y
takes off at .9c toward the distant star, will both X and Y perceive the
same red-shift?
Dave!
