Animal Crossing: Wild World/Time Traveling

Time traveling, simply put, is using the "reset clock" feature in the options menu to change the time and date. This is useful for getting things to happen immediately (e.g. getting fruit to reappear after you've picked it all, getting mail sooner, and so on). The only bad part about traveling is weeds. In order to do this you will need to pick up the phone in your attic before you wake your character up.

If you time travel backwards so a character doesn't move, don't try it. It doesn't work. Weeds come up when time traveling to the future but traveling to the past is easy to get something from Nook's Store that you missed or so on.
