One photon in a void. It is moving at the speed of light because the laws of physics dictate it. We just cannot measure it in this environment.
Two photons side by side and again, they must be moving at the speed of light, but again, no way to measure it.
Effectively, there is no time in the first two scenarios because the photons will travel forever with nothing to dissipate them and they do not age. Nothing is changing. No matter how long they travel or how far they travel, they will always seem to be stationary and unchanged in the center of the void.
Now that we have thrown you into the void, we have time. We have measurable motion, though we still cannot say absolutely whether you are moving or they are moving. All the math, Newton, Einstein, QM, whatever, will say the same thing regardless of which is moving. All we can state as a fact, is that the distance is increasing.
Motion and change are interchangeable in this dialog. Without either, we cannot have time as there is nothing to measure, so existence does not equate to time. Now time did not magically come about just because you were thrown into the mix, but the ability to observe and measure change did.
Make sense to this point?
Yes, only it turns out time did magically come about just because I was thrown into the mix. At least that's what I'm getting at this end. And time might be defined as the deliberate observation and measurement of change, right?
