Time=Sun?

When I think about the existence of time, I don’t see how time cannot exist. As humans we are completely dependent upon time. Time determines when we go to work, our age, the day of the week, as well as many other important aspects of our lives. I believe that time is completely dependent upon the sun. The days of the week, seasons, hours, and minutes are all mathematically calculated by the sunlight. It is evident that this is true because there are various time zones around the world that reflect the amount of sunlight received. Time zones were created so that 12:00pm has the same consistent amount of light throughout the world. Perhaps we use the sun’s light as a way to describe and measure our day, which has been mathematically divided into minutes and seconds so that we can better describe our day, thus creating something that we call “time.”

But how could an event exist without time? I suppose I do not have a full answer to the question about the existence of time yet. I do however believe that we could have the idea of time completely wrong, and that we are interpreting this possible “4th” dimension wrong. If this was the case, then many physics and other mathematical problems that include “t” or time would be incorrect, thus misinterpreting more aspects of our world.
