Since your Pokemon gain exp for each step you take, making your character take more steps than normal (like, ride a bike or something) will make your Pokemon level up faster.
you let him came and stay with you and that will make the days go by faster or break up with him if he does not
No.
All you have to do is just put a pokemon (preferrably a level 100, or at least your highest leveled pokemon) in the front of your party, and give the pokemon you want to train up the exp. share. Then it will get a share of the exp. points. The reason you would want a level 100 in front is because then the pokemon holding the experience share will get 100% of the exp.
use rare candies, an exp. share, and battle the people in the elite four (you get a lot of exp poindts that way.
Turning the screw up will make the pendulum go faster on a clock. The screw adjusts the length of the pendulum, and a shorter pendulum will swing faster.
