  The conclusions summarize the main, but not all, aspects of a two-days
workshop held at MITP Mainz. The four covered aspects are T violation in decays
of neutral B mesons, T and CPT studies in B0B0bar transitions with Belle,
future measurements of T violation in B and D decays, and direct tests of T and
CPT symmetries in the entangled neutral Kaon system at a ?Phi factory.
