  The matter antimatter asymmetry in the Universe is one of the outstanding
problems in physics.and cosmology. CP violation (CPV) is a necessary condition
for generating such asymmetry but the amount predicted in the Standard Model
(SM) from quark oscillations is too small by several orders of magnitude. The
dynamical time operator derived together with Dirac's Hamiltonian from the
Dirac canonical quantization of special relativity is shown to exhibit a CPV
inversely dependent on mass. Applying to all fermions, it follows that extended
Standard Models (ESM) with massive neutrinos contains a much larger CPV as the
electron and muon neutrino masses are six to nine orders smaller than the up
and down quarks masses. Furthermore, it also follows that the CPV differs
between neutrino and antineutrino, in agreement with the T2K observations.
