That is totally dependent upon the speed of the rocket.
Explanation:
The most recent trip to mars by the New Horizons satellite took about 9.5 years so it would take 19 years round trip, earth time.
Now if you place a human inside that rocket things change because of Einstein's theory of special relativity. Because of this that astronaut would observe a slightly slowed down time. But the distance, time, and speed are not great enough for the human to be much more than a few minutes or so younger than had he stayed on Earth.
