Time-space as commonly understood, in the sense of the distance measured between two time-points, is the result of time calculation.
Martin HeideggerThe mathematical is that evident aspect of things within which we are always already moving and according to which we experience them as things at all, and as such things. The mathematical is this fundamental position we take toward things by which we take up things as already given to us, and as they must and should be given. Therefore, the mathematical is the fundamental presupposition of the knowledge of things.
Martin Heidegger
