Time is perceived and represented visually relative to cycles, events, measurements, motions, changes, and transformations. Cores from ice, rocks, sediments and trees contain time dependent layers. Iterative irreversible events (generally planetary) define time; (entropy is ‘time’s arrow’). Radioactive decay is used in dating very long processes. Time is a dimension of space in relativistic physics. [See magnitude.]
