time is a man made thing, dividing days up into hours and minutes and seconds dosent happen in the animal world there is just night and day.
Not so. Many, if not most animals have a keener sense of time than humans do. Anmals know the passage of the seasons by the minute-or-two daily change in the length of the day. They know of the approach of spring and summer by the lengthening of daylight hours from one day to the next. Even some plants can detect this..

If time is limited (for example a lifetime), it must have a beginning and an end - and 'consume' something from one point/position to another. This may not be the case in an eternal context or dimension, but on earth, this very real, non-illusionary change is observable (ie; seasons, age, ...distance). Its consistent repetition makes it quantifiable and measurable.
Therefore, while 'time' as an observable, repeatable change is real and will be consumed, whether people measure it or not. However, its measurement and division into subsets (years, weeks, hours, etc) is an artificial construct.
Don't confuse how time is measured by dividing the periodic motion of the planet on its axis into seconds, minutes & hours with time itself-- really no different than measuring space in cm, m & km.
Interesting observation abut time as a "distance'-- As we should all know, the path of a thrown ball takes the shape of a parabola as it goes from it's start to finish. Graph it so the x axis is its position over the ground and the y axis its height above the ground....Now if we throw it straight up, it will fall straight down-- graphed as a straight line….unless we change the x axis to its position in time (and not distance along the ground). THEN it traces a parabola again--->
We usually say that gravity accelerates the ball because it covers increasingly more "y" with each tick of the "t" but Einstein would just say that gravity distorts the fabric of space-time, so there is increasingly larger distance from one "Y" to the next "y" with each tick of the "t"( !!)….Conventional physics says gravity is a "Force," but Einstein says it's just a the way a mass distorts space-time.
Consider this: we're in a high flying space station in orbit exactly over the equator in such a way that we're always above the same spot over the ocean. We watch two jets take off from a runway on the equator in S. Am. at the same time. They fly east aiming to land on a runway also on the equator in Africa...Each takes a "Great Circle Route"- the shortest distance between two points on a sphere-- but one plane take the route that goes north of the equator and one takes the route that goes south.....
----As we watch them from high above, they appear to be flying away from each other until mid route, then they appear to be approaching each other again as they near the final destination--- We might think there is a "Force" that separates them, then draws them closer, but it's really only a function of the geometry.....Sounds kinda like Einstein's gravity and space-time, doesn't it?
It is minutes. Birds can detect now, in January, that each day is now slightly longer than yestarday, and they have begun their nesting behavior in my yard, despite the uniform climate..
Last summer, our chorus of tree frogs suddenly began singing after dark, within ten minutes of the same time every day, even though the time of sunset changed every day.
If you have swallows or martins nesting near your house, they will return from migration the same day every year, regardless of the weather.
Poinsettias turn red when the hours if daylight is exactly twelve.
Captive emus born in in Canada breed in winter, because their species remembers when it is summer in Australia and they think it's summer everywhere.
They all have a body clock, that has been running since long before man "invented" time..
