\begin{abstract}
The concepts underlying the Lorentz transform for time dilation and
length contraction are presented. The notion of a rest frame is
introduced and its usefulness discussed. The rest frame of the CMB (the
Hubble frame) is proposed as the correct candidate for the rest frame in
the Lorentz transform, and an equation developed to compute the relative
time dilation between inertial frames based on this assumption.%
