The theory of multiple times considers the existence of four times: irregular time, mathematical time (t in equations), psychological time and relative time. In general, time is the continuous succession of irreversible changes. Time is the continuity of movement. Actually we find events with variable or irregular rhythm, such as the current of a river or the flight of birds. The mathematical time has uniform and periodic rhythm, and is taken as reference to measure the duration of events. Clocks are an example of mathematical time. The relative time is affected by speed or gravity.
