Transport Giant (UP)

This is cummulative and unlocks directly in-game when you pass 1 hour. When you play the story you can not really pause the game, only reduce time speed to 0. However, this does not affect this achievement.
You can start the first mission press LB to freeze time and let it sit for how long you want. If you want to get the other time achievements but not in one session: save the game, quit and come back later.
