Your stuff doesn't add up. How do you explain the fact that if you sync three clocks, take one to NY, one to Florida, and one to Virginia (Mid point between clocks) that each observer will see their own clock as running ahead of the others, and that the Virginia clock observer will see the other two clocks in sync with each other, but behind his own clock? So previously, it was agreed that each observer at each clock would send a light signal at precisely 12:00:00. The clocks all strike 12:00:00 simultaneously, and the light signals are sent. During the time of light travel, the observer in Virginia travels a distance away from his original mid point position, so the light from Florida reaches him at an earlier time (according to his clock) than the light from NY reaches him. So since the observer in Virginia traveled a distance during the time of light travel, it is impossible for him to see the other clocks as in sync with each other, and different than his own.
