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 us to be clear on how we understand what is time and what are its properties, which we explain in brief as follows (for the more complete analysis see: [54], [64], [65], [66]).
