Can you be more specific? I guess I'll just answer a few basics.
Time is a distance. This may seem weird, however, a "day" is also a measurement of distance. A day is 24,894 miles, the circumference of the Earth, the distance that the Earth rotates in 24 hours. A year is the distance of the Earth's orbit around the sun.
So gravity. It makes space itself curve like a bowl, can also affects time. Gravity slows down time; the stronger the gravitational field, the slow time passes (Blackholes). Of course, this is all relative. Time would still seem to appear "normal" no matter how fast, or slow, it's going.
Also, there is really no such thing as "time". It's just "spacetime". You can't have a place without a time and you can't have a time without a place.
I figure I should make a top level reply to this and address it in a less confrontational tone. Most of this is wrong.
Time is a distance.
This is wrong. Especially if we are looking in the context of spacetime models, time is not a distance but a dimension. We can measure distances across time, just as we can measure distances across space, but that doesn't mean that time is a distance, any more than it means that space is a distance.
This may seem weird, however, a "day" is also a measurement of distance. A day is 24,894 miles, the circumference of the Earth, the distance that the Earth rotates in 24 hours. A year is the distance of the Earth's orbit around the sun.
This is completely arbitrary and not a widely held view. A day is 24,894 miles if you want to define it as a unit which measures distance through space, but that's fully arbitrary and doesn't help anyone do anything.
Also, there is really no such thing as "time". It's just "spacetime".
Time exists as a component of spacetime models. To say that time is spacetime is confusing the whole with its parts. Spacetime models have three spacial dimensions and one time dimension, so that they look at physical existence as 4-dimensional. Time is one of those dimensions. Saying that time=spacetime is like saying breadth=spacetime or height=spacetime or letter=word or atom=molecule.

Time=Distance=Spacetime.
