What really screws me up concerning time is the idea that it can travel faster in different places. They say stars bend time, much like they have gravity. I see gravity as a bend in the 3 dimensions - put a few marbles on a sheet, put a cricket ball in the middle, watch the marbles approach the cricket ball... anyway, it's pretty nuts to think if you were closer to the sun, time would pass differently for you, to the observations of an outsider. So, if I lived near the sun, then I would die before someone not living near the sun... I'd age quicker... it's confusing me now!
