The answer depends on what the question is really asking.
(a) If it's asking whether the phenomena that the word "time" signifies is real, the answer is yes. We observe it everyday in our lives.
(b) Can the word "time" also be used to refer to our conception of the phenomena of time? Sure. We use clocks and numbers and dates to identify points of time. We have words like past, present, and future. We use different verb tenses to communicate different spans or points of time in relation to the present. I even suppose a video game maker would have conceive an understanding of "time", and then simulate it in a video game.
Those who've answered that "time" is merely a concept appear to be referring to the word "time" that we humans have created. They fail to understand that the question is likely (1) asking about the phenomena that the word "time" signifies, or alternatively (2) deliberately engaging in linguistic trickery by equivocating between the word "time" and that which it signifies in the real world.
Perhaps even the question was constructed to test who could detect the difference between words and meaning, a common topic in the philosophy of language. https://plato.stanford.edu/entries/peirce-semiotics/
John Polkinghorne, a quantum physicist and Anglican priest, believes that the flow and direction of time are real and relentless. It is a "mistaken argument," he said, to use relativity to assert that time is an illusion, "because no observer has knowledge of a distant event, or the simultaneity of different events, until they are unambiguously in that observer's past. And, therefore, that argument focuses on the way observers organize their description of the past and cannot establish the reality of the awaiting future."
Polkinghorne rejects the notion of the static block universe of space and time together. "We live in a world of unfolding and becoming," he said.
Fotini Markopoulou-Kalamara, a theoretical physicist at the Perimeter Institute, said, "I have the distressing experience of physicists telling me that time is not real. … It confuses me, because time seems to be real. Things happen. When I clap my hands, it happened. … I would prefer to say that general relativity is not the final theory than to say that time does not exist."
Time is a prime conflict between relativity and quantum mechanics, measured and malleable in relativity while assumed as background (and not an observable) in quantum mechanics. To many physicists, while we experience time as psychologically real, time is not fundamentally real. At the deepest foundations of nature, time is not a primitive, irreducible element or concept required to construct reality.
The idea that time is not real is counterintuitive. But many ideas about how the world works that humanity had taken for granted have required a complete rethink. As Tegmark puts it, "There've been so many things in physics that we thought were fundamental that turned out to be mere illusions, that we're questioning everything — even time."
What reality is depends on what time is. Is time irreducible, fundamental, an ultimate descriptor of bedrock reality? Or is our subjective sense of flowing time, generated by our brains that evolved for other purposes, an illusion?
Opinion is divided, but many physicists and philosophers now suspect that time is not fundamental; rather, time emerges out of something more fundamental — something nontemporal, something altogether different (perhaps something discreet, quantized, not continuous, smooth).
The alternative, of course, is our common intuition: time does flow, the present is super special as the only real moment, and the deep nature of reality is one of becoming.
What is time. Time is a measurement of a change in state. Before humans had the concept of time, thing where changing state. For example the humans knew that they would get older. The sun rises and sets. The seasons come and go. None of that would be possible if time did not occur. Without time there would be no change. The universe would be like a picture. The objects in it would not move.
So time is a change in state. Time is also directional. Cause come before effect. People get older not younger.
It is true that humans standardized time to help us predict when some will happened. However, the fact that something happens at all is due to time. What we did not invent time. We only invent standard measurements of it (i.E., seconds, hours, days, year, decades, centuries, and millenniums
The word 'time' was created by humans, the mechanisms that were made to measure time were also created by humans, but the underlying principle of time always exists. Before watches and clocks were made there were many other methods of measuring time, but different methods doesn't mean time can exist in different ways, the concept of time always stays the same regardless.
Humans did invent standardized measures of time for convenience sake, but time itself is a real force in nature. Using Einstein's Theory of Relativity as an example, time slows down as objects speed up (and this effect is demonstrated all the time with satellites). If time were merely a human construct and didn't actually exist, its passing would be unaffected.
By the scientific definition, yes, time does exist. Time is an integral part of our universe and dictates that change and movement can occur, in fact spacetime can be used as an absolute measurement to determine how physical processes in different locations interact with each other. Without it the Second Law of Thermodynamics would be meaningless, which are significant to nearly all scientific inquiries in some way.
Time is a concept unique to humans (and some other mammals). Humans use time as a type of standard to keep track of the past. Also, time is a helpful tool in science and really any subject to measure how things change. I believe time was created through human reflection; we use it to figure out ourselves and the world around us.
Change is palpable, observable and real. It is irregular and unpredictable. What we decide to do with all this is to use the most regular of entities ie day/night, egg timer etc This allowed us to standardize the amount of time within which changes occur. That is why it takes twice as long to eat an apple than it does to eat an orange. Time is a human invention akin to number and geometry. Try catching a five with a triangle and do it within an hour. GO!
Time was created by humans. There is no evidence backing up the whether or not time is real. We decided that second was what it is and that 60 of those world make a minute and so on and so forth. While the moon and sun are destined to rise and set, we created the concept of day and night and how to measure how long each was. There is no evidence of time because time only exists in our minds.
As you read this sentence, you probably think that this moment—right now—is what is happening. The present moment feels special. It is real. However much you may remember the past or anticipate the future, you live in the present. Of course, the moment during which you read that sentence is no longer happening. This one is. In other words, it feels as though time flows, in the sense that the present is constantly updating itself. We have a deep intuition that the future is open until it becomes present and that the past is fixed. As time flows, this structure of fixed past, immediate present and open future gets carried forward in time. This structure is built into our language, thought and behavior. How we live our lives hangs on it.
Yet as natural as this way of thinking is, you will not find it reflected in science. The equations of physics do not tell us which events are occurring right now—they are like a map without the “you are here” symbol. The present moment does not exist in them, and therefore neither does the flow of time. Additionally, Albert Einstein’s theories of relativity suggest not only that there is no single special present but also that all moments are equally real [see “That Mysterious Flow,” by Paul Davies; Scientific American, September 2002]. Fundamentally, the future is no more open than the past.
Time has long been a major subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without circularity has consistently eluded scholars. Nevertheless, diverse fields such as business, industry, sports, the sciences, and the performing arts all incorporate some notion of time into their respective measuring systems. Some simple definitions of time include "time is what clocks measure", which is a problematically vague and self-referential definition that utilizes the device used to measure the subject as the definition of the subject, and "time is what keeps everything from happening at once", which is without substantive meaning in the absence of the definition of simultaneity in the context of the limitations of human sensation, observation of events, and the perception of such events.
Two contrasting viewpoints on time divide many prominent philosophers. One view is that time is part of the fundamental structure of the universe—a dimension independent of events, in which events occur in sequence. Sir Isaac Newton subscribed to this realist view, and hence it is sometimes referred to as Newtonian time. The opposing view is that time does not refer to any kind of "container" that events and objects "move through", nor to any entity that "flows", but that it is instead part of a fundamental intellectual structure (together with space and number) within which humans sequence and compare events. This second view, in the tradition of Gottfried Leibniz and Immanuel Kant, holds that time is neither an event nor a thing, and thus is not itself measurable nor can it be travelled.
Time is merely a concept.
If we run out of time, where does it go?
Is time even real?
Does anyone know?
Maybe time's just a construct of human perception. An illusion created by-
Meh, meh, meh, meh,

Hi friends, fuckboysteve again...
Many people overlook time as just being some sort of measurement. Let me tell you my friends that it is not. Time is actually a physical thing created by the Illuminati in the 18th centuary in conjunction with the reptilian form of Barack oBama. TIme is being used as a BAIT MY FRIENDS A BAIT AHHHH
