Time is a dimension in which events can be ordered from the past through the present into the future, and also the measure of durations of events and the intervals between them.

It has been said that time is used by the universe to ensure that everything doesn't happen all at once.

It has also been said that: "Time is an illusion, lunchtime doubly so." Not everyone agrees on the nature of time, and time is not fully understood even today.
