in my book i think that on any planet if we can stay for 1 year then on earth how much time are gone

A "year" on a given planet is the length of time it takes that planet to complete one rotation around its sun. We would need to know the length of the year on that planet to answer your question. This has nothing to do with relativity.

but i think that there is much gravitation then erth then any effect in our time

It is extremely hard to understand what you are saying. Could you take a little more time to type out your posts or get someone to help you translate?

Anyways, the difference in time dilation between a planet and earth depends entirely upon the force of gravity at the surface of the planet. Even a planet that is 2x as massive as the earth might have less gravity and less time dilation at the surface compared to earth if the density is low enough. In any case, the difference is very very small.

but because of huge gravitation a spacetime can bend or twist. I think that because of this time can slower then the earth. Simple.

General relativity describes all gravitational fields (not just extremely strong ones) as curvature of spacetime.

Time runs faster in interstellar space, for example, than on the earth's surface. To find a place where it ran slower, you'd have to go into a deeper gravity well, e.g., near the sun.

Gravitational time dilation has been measured between different heights on the earth: http://en.wikipedia.org/wiki/Pound-Rebka_experiment
