The following link contains two or 3 differing concepts of time. https://www.quantamagazine.org/does-time-really-flow-new-clues-come-from-a-century-old-approach-to-math-20200407/
The SO(4) physics model of nucleons is a model including a temporal time scale associated with a magnetic rotating flux at a specific frequency. This “temporal time” reflects space parameters and the observed phenomena of EM photon propagation in space controlled by those parameters , magnetic permeability and electric permittivity. A good model for space and its “intrinsic” parameters is warranted IMHO. Bob Cook
