content: We measure Hours, Days, Months, and Years by the Sun and Moon's arc across Earth's sky. We can measure minutes by turning an hourglass, the turning of clockwork, or counting the oscillations of quarts. Just as distance is the measurements of height, width, and depth between two objects,  Time is the measurement of relation between two objects in motion. Time is not a dimension of space, it has magnitude but no direction nor orthogonality.
