Time

Absolute and mathematical time is an indefinite period, continued progress of existence and events that occur in apparently irreversible succession from the past through the present to the future. It is time between two points on a theoretical timeline. It can be measured in seconds (basic SI unit), but a lot of other time units are also in use.

Base unit for Time: second [s]
