Time is a basic scalar physical quantity that measures the duration of an event, the intervals between events, as well as the motion of objects through space. It is a non-spatial linear continuum that is apparently irreversible. Basic divisions of time include past, present, and future. The past is final and cannot be altered. The present is unfolding. The future is to be anticipated. Common units of time measurement include seconds, minutes, hours, days, weeks, months, and years. Common timekeeping devices include clocks, watches, and calendars. Clocks and watches measure units smaller than a day such as hours, minutes, and seconds. Calendars measure units greater than a day such as weeks, months, and years. The basic SI unit of time is the second (s). Time passes more quickly or slowly depending on the observer's motion through space according to the general theory of relativity. The second law of thermodynamics states that matter decays as a result of entropy due to the passage of time.

∙ 6y agoTime is the physical quantity that measures the rate of a process in the universe. It also consists of the entire history of the universe in terms of a process from singularity to simplicity to complexity to entropy. It is measured using the SI unit of the second.
