My problem understanding Time?

I wanted to know about something that has puzzled me for a while now. Im not a cosmologist or physicist so there is probably a simple answer to this question. Which is, we know that time doesnt run at a constant rate everywhere in the universe, such as, it runs slower for say someone on the earth than someone on a space station(only by a minute amount but gravity still effects it)so is it right in saying that the further you are away from an objects gravitational pull the faster time will tick???and if this is correct then what speed would time be going if you were somewhere say between galaxies and there was no gravitational disturbance of time???...im sorry if im making no sense as i only have a very little understanding of this subject but would love someone in this field of science to explain this to me..thanks alot
