How can this be? The rocket is a rigid structure, the front and rear clocks accelerate at the same rate.
First, there are no rigid objects in relativity theory. Otherwise they could be used for FTL signaling. Second, there is no simultaneity at different places, like the front and rear of the rocket. So it is frame dependent whether the two ends of the rocket begin to accelerate at the same time.
