  The observed CP violation in neutral kaons experiments is explained as an
interplay between two oscillations in the earth's Schwarzschild geometry: (i)
mixing associated with second order weak coupling and (ii) quark's
zitterbewegung. This violation is in fact a CPT violation with T conservation
rather than a T violation with CPT conservation. The Hermitian evolution of a
stable kaons system leads to the identification of this CPT violation. Then,
the finite lifetime of the short-lived kaon rotates the violation parameter
such that it appears as a T violation.
