"The precise chronolgy of the Zelda universe is hotly debated among fans, although some fans do not feel the games are definitively connected. As the series progressed and more games were released, the exact order of the games in an overall timeline became complex and heavily disputed. The most common theories are that most games take place with a different Link, as hinted by Miyamoto in many interviews, or that the games follow a split timeline, parallel universes created by the ending of Ocarina of Time. It is often concluded by many fans that no specific timeline is necessary, and that each game is simply a new retelling of one core Legend of Zelda thesis.
In an interview that Nintendo Dream conducted with Eiji Aonuma in December 2006, he mentioned that there could exist two universes. The split in the timeline occurs during Ocarina of Time, when, at the end of the game, Link is sent back in time by Zelda. Once returned to his original time, Link goes to see her again, and the result of this meeting is an alternate future in which the villain Ganondorf is arrested and tried by the ancient sages, which causes him to get banished to the Twilight Realm; Twilight Princess then occurs over a hundred years after the Ocarina of Time child Link's era. Meanwhile, The Wind Waker occurs in the 'original' timeline, hundreds of years after the adventure of adult Link in Ocarina."
"The creators maintain that the series has a set timeline, but due to the poor translation protocols in the 1990s, and debate over what counts as "canonical" material, the available information continues to be disputed. Eiji Aonuma has since promised he will do his best to patch it all up, and reveal the timeline someday, and Miyamoto stated in a 2003 interview that there is a master document containing the timeline. Eiji Aonuma has also stated in a July 2007 video interview that there is such a document on his PC, and that this document is considered confidential. According to this interview, development of a Zelda title can commence without the team knowing in advance where exactly the title will fit into the timeline; but by the time the title is finished, its placement in the timeline will be determined. However, this document has not been seen publicly, and there is little other proof of its existence."
