Tripppppyyyy dude.
"Time" has not always existed.
The theory of relativity suggests that before the Big Bang 13.7 billion years ago, space and time did not exist and matter was packed together in a tiny ball.
Since time is measured by motion in space, there was no time without moving cosmos.
Time on Earth is actually slowing down.
Due to tidal friction from the sun and moon, the solar day is lengthening by 1.7 milliseconds each century as the Earth's rotation slows down.

Dinosaurs had to fit a full day's work into just 23 hours.
In 140 million years, a day on Earth is expected to last 25 hours.
Cultural background affects our perception of time.
Time perception differs dramatically across the globe. For example, Americans tend to think about time in 5-minute increments, while Middle Easterners do so in 15-minute increments.
This means that an American's five minute siesta and a Middle Easterner's fifteen minute siesta are actually experienced as the same length of time.
