  We comment on CP, T and CPT violation in the light of interesting new data
from the CPLEAR and KTeV Collaborations on neutral kaon decay asymmetries.
Other recent data from the CPLEAR experiment, constraining possible violations
of CPT and the $\Delta S = \Delta Q$ rule, exclude the possibility that the
semileptonic-decay asymmetry $A_{T}$ measured by CPLEAR could be solely due to
CPT violation, confirming that their data constitute direct evidence for T
violation. The CP-violating asymmetry in $K_L \to e^-e^+\pi^-\pi^+$ recently
measured by the KTeV Collaboration does not by itself provide direct evidence
for T violation, but we use it to place new bounds on CPT violation.
