It is the frequency that is red-shifted, not the
velocity. A shorter second results in a lower
frequency. Relativity won't allow the velocity
of light to change but everything else changes
including meters and seconds.


Quantum mechanics does however:

On a more humble level, Light changes speed as it passes through
different mediums, such as water.
