  The laws of quantum physics can be studied under the mathematical operation T
that inverts the direction of time. Strong and electromagnetic forces are known
to be invariant under temporal inversion, however the weak force is not. The
BaBar experiment recently exploited the quantum-correlated production of pairs
of B0 mesons to show that T is a broken symmetry. Here we show that it is
possible to perform a wide range of tests of quark flavour changing processes
under T in order to validate the Standard Model of particle physics covering b
to u, d, s, and c transitions as well as c to u, d and s transitions using
entangled B and D pairs created in Y(4S) and psi(3770) decays. We also note
that pseudoscalar decays to two spin one particle final states provide an
additional set of CP filter bases to use for T violation tests.
