Return Trophy in Journey
Start the journey again after a week long break.
How to unlock Return
As the trophy description explains, after a week long break from this game, launch it to unlock this trophy.
If you want it quicker (or simply can't keep away for a week ), here is how to get it right away. After having played and the game is done saving, quit the game via XMB, manually set the date quickly by choosing the next year, and then relaunch the game - this will unlock at the main menu. Don't forget to set the date back, you can have the PS3 set it via Internet.
