You can change your in-game time zone once every 30 days. To change it:
- Change the time zone on your computer to the desired one.
- Launch the game and click your avatar in the upper left corner.
Click the pencil button next to your current time zone. Your time zone will automatically update, and the game page will reload.
- After synchronizing the in-game time zone, you can switch back your computer time zone.
This change affects game modes and quest reset time.
