I refer here to the case of a light clock where theeach light pulse usedemitted travels back and forth and then reflected back between the two plates of the clock on the same axis as the direction of the moving clock:

Assuming you are using very short duration light pulses much shorter in duration than the time it takes them to travel to the opposite plate in the case where the clock was stationary, then when the clock is on the move and you registerregister only the pulse moving in the same direction with the clock when it reaches the opposite plate, the result will be yes time dilation for the time recorded by thethis clock.

However my question is, if you register the time instead, of the reflected light pulseonly by using the reflected light pulse coming back to the initial plate, then will there be any time dilation effect?

Case of moving longitudinal light clock with no time dilation?
