Time travel

Time travel, sometimes called TTing or time traveling, is when the player manually changes the time of their game to advance to a future event or go back to a past event without having to wait in real time. It is considered by some to be a form of cheating, with players arguing over its usefulness and legitimacy.

Changing the time of date does not affect villagers, weeds, flowers, hair, trees, dump/recycling, mail, bell bank, turnips, police station/lost and found, or construction. It will, however, affect sun/moonlight season, weather, and the time until a holiday or event.

How to Time Travel
There are different ways to change the clock time in each console the games were released on. Below address how to change the clocks:

In Animal Crossing
To change the time in there are two options - the Nintendo GameCube clock or the in-game clock access through the in-game options. The ideal option is to change the GameCubes interntal clock, because the in-game clock effects the growth of trees, the way letters are sent and how the Police Station and Dump restock with items.

To access the GameCube menu, hold 'A' while the GameCube is starting up. Follow the on-screen options.

In Animal Crossing: Wild World
To change the time in-game, load the game and when at the character select, click the phone and follow the option that goes to the Date and Time settings.

To change the DS time, turn on the DS then touch the screen/press "A". Instead of loading Wild World, press the DS icon at the bottom of the touch screen. Click the second menu, the blue one. The top button changes the date, the right button changes the time, and the middle one changes the alarm. Press "B" until it asks if the system should shut down. Click "A" and load the game up as usual.

To change the DSi time, choose settings and the time, then press B and start the game as normal.

In Animal Crossing: City Folk
Like in the original Animal Crossing, there are two options to change the date and time settings for. The easier option is to change the Wii date and time instead of the in-game date and time settings. This is again due to the in-game settings effect the bank interest, plants and trees.

To change the Wii time settings, go to the Wii Menu and click the 'Wii' button at the bottom left of the screen. Once there, go to 'Setup' and find the menu which opens up the Date and Time settings.
