We revisit various results, which have been obtained by the BABAR and Belle Collaborations over the last 13 years, concerning symmetry properties of the Hamiltonian, which governs the time evolution and the decay of neutral 
mesons. We find that those measurements, which established CP-violation in meson decay, 13 years ago, had as well established 
(time-reversal) symmetry violation. They also confirmed CPT symmetry in the decay 
and symmetry with respect to time-reversal 
and to CPT 
in the 
oscillation.
