Popis: A detailed description of the analysis of neutral kaons decaying to e pi nu is given, based on the complete set of data collected with the CPLEAR experiment, Using a novel approach involving initially strangeness-tagged K-0 and (K) over bar (0), time-dependent decay-rate asymmetries were measured, These asymmetries enabled T- and CPT-violation parameters to be measured in the context of a systematic study. The highlights of this study arc the first direct observation of T violation and the direct determination of the CPT parameter Re(delta) with an accuracy improved by two orders of magnitude with respect to the current value.
