ABSTRACT
All processes, motions and movements, all behaviors of systems and their responses, as well as all external actions on the systems, occur and propagate in time. It is natural from the physical point of view to study systems directly in the temporal domain. This requires to be clear about how we understand what is time and what are its properties. It was explained in brief in 68, 69 and for the more complete analysis can be seen in 64, 65 and 66.
