FYI, the term “Time Reversal” has long been used by physicists to describe a symmetry of quantum mechanical processes with regard to flipping the sign of t (ie, time). Just like Charge and Parity symmetries which flip the sign of electric charge and position. See https://en.m.wikipedia.org/wiki/CPT_symmetry https://en.m.wikipedia.org/wiki/CPT_symmetry
