The best I've ever imagined as what time really is to us is that it is a form of energy relating to the expansion of the universe, and light.
I tend to think of the Universe as an expanding bubble that started with the "Big Bang". The way I see it is without time, there is no universe. Light and energy spread out, but somewhere that light has not reached yet simply cannot exist since this energy has not reached there in order for us to have a measurable understanding of such a place. Objects could not move, therefore atoms could not exist in a place which does not feel time.
I wonder about Gravity's effect on light, and the expansion of the universe. Since Gravity does have a pull on light would it not make sense that light would move slower in the presence of Gravity? If so would time and light move faster in intergalactic space therein causing us to have the age of our universe wrongly calculated?

I have one observation on this and two answers. 1. Remove your idea of your senses. If you are with out your senses and imagine you are immortal. Then you are a thought in the void. Does light have to reach a certain area for time to exist, if there is nothing there to reflect the light to an observer. Your initial question is a lot like the question: If a tree falls in the woods and no one is there to hear it does it make a sound. If you you are blind does light exist. Consider dark matter as well. On the gravitational effect on light, research Gravitational Redshift.

Perhaps time could be thought of as the numbers of a clock corresponding with the way particles move during that hour.
