'Time' In the math books, time is known to be an ongoing and continuous sequence of events that occur in succession, from the past through the present, and to the future. Time is used to quantify, measure, or compare the duration of events or the intervals between them, and even, sequence events.
Physicists explained time as the progression of events from the past to the present into the future. Basically, if a system is unchanging, it is timeless. Time can be considered to be the fourth dimension of reality, used to describe events in three-dimensional space.
The books told me all this and more importantly, the universal essence of time is 'Time waits for no man' . The passing of time is unstoppable, and it will march on regardless of what anyone says or does.
