To a certain extent you are correct, although time was not created by a particle that started to move in "space". Time is a human factor here.
"time" does not have the same significance anywhere. Thus can not be generalized by human calculation.
What is persived as an hour here could be months in another planetary system. While orbiting Mars "time" is not exactly the same as when you are orbiting Earth but humans calculate it the same way none the less!
That is because time is RELATIVE. Maybe you should read up on Relativity, you know, Einstein? For example, light does not travel faster in different areas of the galaxy, it is a constant. Therefore the time it takes to travel a specific distance is the same nomatter where it is.
