Ie, they measure space directly and from that measure we manufacture or infer a measurement of time. Given space and motion, time becomes only a counting of displacements generated by motion over space. Motion is real, space is real. Time is the ghost of dead motions. Or, time is a parameterization of an equation in motion and space.
