Definitions of Time !
1) Time is a measure 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.
2) Time is the dimension on which the evolution of state of a system is allowed to occur.
3) Time is a necessary parameter in order to describe observed changes in three dimensional space, dx/dt, dy/dt, dz/dt. If there were no observable changes in the (x,y,z) contour map of the world (including us as contours also) there would be no time parametrization needed.
4) According to Albert Einstein "Time is what a clock measures" .
5) Time is measure of rates of change .
6 ) What prevents everything from happening at once
7) A linear continuum of instants
8) A certain period during which something is done .
9) A continuum that lacks spatial dimensions
10) The indefinite continued progress of existence and events in the past, present and future regarded as a whole (Oxford Dictionary)
11) The measured or measurable period during which an action, process or condition exists or continues (Webster’s Collegiate Dictionary)
12) The continuous passage of existence in which events pass from a state of potentiality in the future, through the present, to a state of finality in the past (World English Dictionary)
13) a continuous, measurable quantity in which events occur in a sequence proceeding from the past through the present to the future (Science Dictionary)
14) The measured or measurable period during which an action, process or condition exists or continues (Merriam-Webster Dictionary)
15) the dimension of the physical universe that orders the sequence of events at a given place (McGraw-Hill Encyclopedia of Science and Technology)
16) A non-spatial system in which events appear to happen in irreversible succession (Words Myth Dictionary)
17) The inevitable progression into the future with the passing of present events into the past (Wiktionary)
18 The indefinite continued progress of existence and events in the past, present, and future regarded as a whole (Google)
19) 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 (wikipedia )
20 ) Time is the ongoing sequence of events taking place. The past, present and future.
21) The duration or interval of change
22) According to my point of view ( i.e Admin ) , the change occur in the whole universe in any form ( temperature , pressure , energy , direction of any thing , speed etc etc ) at any place is called time ! Point to be noted that I mention change in any form and at any place in whole universe .
Note ;-
And plz dont compare these definition of time with Einstein quotes " Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute. That's relativity.” -
AT LAST :-
According to " Isaac Newton "
I do not define time, space, place, and motion, as being well known to all.
Thanks !

What is yours opinion about time in Physics ?
