There’s no doubt that time commands our everyday lives in many ways. Everything we do depends on time since most obligations have been structured based on the twenty-four hours of the day: the hours we work, the hours we rest or sleep, the times we’re allowed to do certain things (you’re not supposed to play loud music at two in the morning, for example), and so on. More importantly, our existence is controlled by time as well, since aging and eventually dying is directly intertwined with time as we perceive it. However, according to thinkers, scientists, and philosophers, the concept of “time” is a weird one, and the world of quantum physics that attempts to analyze it in greater detail is even weirder. The modern double-slit experiment—a demonstration that light and matter can display characteristics of both classically defined waves and particles; and moreover, that it displays the fundamentally probabilistic nature of quantum mechanical phenomena—attempted to explore the role of consciousness in shaping and influencing physical reality, illustrating even further how strange the concept of time is and how we might never manage to understand it using traditional logic. If this intro has not confused you enough. then feel free to read the following 25 Facts About Time To Mess Up Your Biological Clock. We can assure, these facts about time will make you reconsider a few things about “reality”.
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. To get an idea what a great variety of opinion there is keep in mind that Isaac Newton considered time to be absolute but according to Einstein time is more flexible and relative in scope.

An Egyptian device that dates to about 1500 BCE, similar in shape to a bent T-square, measured the passage of time from the shadow cast by its crossbar on a nonlinear rule. The T was orientated eastward in the mornings. At noon, the device was turned around so that it could cast its shadow in the direction of the nightfall.
Source: Wikipedia, Image: Wikipedia Immanuel Kant, in the Critique of Pure Reason, described time as an a priori intuition that allows us (together with the other a priori intuition, space) to comprehend sense experience. With Kant, neither space nor time are conceived as substances, but rather both are elements of a systematic mental framework that necessarily structures the experiences of any rational agent, or observing subject.
