Abstract
We present a general model-independent and rephase-invariant formalism that cleanly relates CP and CPT noninvariant observables to the fundamental par ameters. Different types of CP and CPT violations in the K-0-, B-0-, B-s(0) - and D-0-systems are explicitly defined. Their importance for interpreting experimental measurements of CP and CPT violations is emphasized. In parti cular, we show that the time-dependent measurements allow one to extract a clean signature of CPT violation.
