This is an example of time dilation due to special relativity. Clocks on a spaceship moving at high speed relative to the Earth will appear to run slower when viewed from Earth. This effect is not noticeable at everyday speeds, but becomes more significant as the speed approaches the speed of light. From the perspective of someone on the spaceship, the clocks would appear to run normally.
