Hi John, One might think it was the acceleration that slowed time on A's clock, BUT the point is that A's acceleration was only 1g throughout the entire trip which was exactly EQUAL to B's gravitational acceleration back on earth. So if the accelerations were exactly equal during the entire trip how could A's acceleration slow time but B's not slow time by the same amount?
