No, light and time are not even remotely the same thing and the only relationship is that time is used to measure the speed of light. Time is a dimension. Light is a quantum object.

Well, I need light to see my watch. (OK, kidding.)

There is a connection between the speed of light, which is a kind of cosmic speed limit, and the nature of time. That connection is detailed in Einstein's special theory of relativity.

That doesn't really make sense.
