Fermilab experiment E773 has measured the phases +-=43.530.97 and 00-+-=0.621.03 of the CP violating parameters +- and 00 from interference in the decay of neutral kaons into two charged or neutral pions from a pair of regenerators. New measurements of the KL- KS mass difference and the KS lifetime are also given. These results test CPT symmetry and show no evidence for a violation.
