In Einstein's physical geometry, the geometry of space and the uniformity of time are taken to be non-conventional. However, due to the stipulation of the isotropy of the oneway speed of light in the synchronization of clocks (or definition of simultaneity), as it stands, Einstein's views do not seem to apply to the whole of the Minkowski spacetime. In this work we will see how Einstein's views can be applied to the Minkowski space-time. In this way, when adopting Einstein's views, chronogeometry is a physical chronogeometry.
