Hmm... not sure what you're getting at. Time is asymmetric, unlike the three spatial dimensions, thus time only moves foward. Time is indeed one of the four dimensions we live in (well, macrodimensions, discounting M-Theory and similarsuch), so I'm not following the time-not-being-a-dimension part.
2 things:
1] Time differs whether you're close to the center of the sun (or wherever the gravity force is high) or where gravity is close to 0
2] That's where it becomes confusing... is t+1 after t?
something about time unlike other dimension does not increase along its axis but things are simultaneous???

Absolute, true, and mathematical time, in and of itself and of its own nature, without reference to anything external, flows uniformly and by another name is called duration. Relative, apparent, and common time is any sensible and external measure (precise or imprecise) of duration by means of motion; such a measure—for example, an hour, a day, a month, a year—is commonly used instead of true time~ Newton. Does that count?

"To travel backwards in time we'd need to unevent events, we’d need negative motion. But motion is motion whichever way it goes. You can’t have negative motion. So you can’t travel backwards in time. There are no time travel paradoxes, because there is no time travel, and there is no time travel because there is no travelling in time. And there never was. Time didn’t start fifteen billion years ago. Because time didn’t start in the first place. It was motion that started in the first place. And it was fifteen billion light years away by every light path you can track through timeless space. "

I guess in simple terms try this (it's how I see it anyway):
Time is our measurement of the passing of motion. Particle Z moves from point A to point B. The amount of energy used to move it and it's mass would determine determine it's time measurement. Double the energy would halve the time. Halve the mass would halve the time etc. So time is the way we can perceive these differences...
Therefore motion must exist before time, because we can't measure something if it doesn't exist.
(After starting this post and doing some searching, this is only one of two main theories relating to time. It refers to time as being part of the "fundamental intellectual structure", not a fundamental structure of the universe which is the other theory.)
