  Assuming a model of aether non-entrained by the motion of celestial bodies,
one can provide a rational explanation of the experimental processes affecting
the measurement of time when clocks are in motion. Contrary to special
relativity, aether theory does not assume that the time itself is affected by
motion; the reading displayed by the moving clocks results from two facts: 1/
Due to their movement through the aether, they tick at a slower rate than in
the aether frame. 2/ The usual synchronization procedures generate a
synchronism discrepancy effect. These facts give rise to an alteration of the
measurement of time which, as we shall show, exactly explains the experimental
results. In particular, they enable to solve an apparent paradox that special
relativity cannot explain (see chapter 4). When the measurement distortions are
corrected, the time proves to be the same in all co-ordinate systems moving
away from one another with rectilinear uniform motion. These considerations
strongly support the existence of a privileged aether frame. The consequences
concern special relativity (SR) as well as general relativity (GR) which is an
extension of SR. We should note that Einstein himself became conscious of the
necessity of the aether from 1916, in contrast with conventional relativity.
Yet the model of aether presented here differs from Einsein in that it assumes
the existence of an aether drift, in agreement with the discoveries of G.F.
