Time has been defined as the continuum in which events occur in succession from the past to the present and on to the future. Time has also been defined as a one-dimensional quantity used to sequence events, to quantify the durations of events and the intervals between them, and (used together with other quantities such as space) to quantify and measure the motions of objects and other changes.
