Paul, that one clock runs a different rate under certain conditions does
not warrant the inference that time itself runs at a different rate
 
Please define "time itself". How can you measure that the rate of
"time itself" is different from the rate of your clock?
 
See:

Can you point out an error in 1.1 "What is proper time"?
 
What is proper time?
It's time measured "loco dolenti," that is, where it hurts, and elsewhere
in the frame of reference, or worse, elsewhere in another frame of
reference.
When someone has pain in a joint, such as the shoulder, you don't inject
the knee. You inject, in loco dolenti.

How does an aspirin know where the pain is?
