Yet, the creators of the Zelda series have gone on record, many, many times, stating that they want the fans to arrange the games how they see most fit. If there was one definitive timeline, it would defeat what they are going for. What you have been complaining about for as long as I can remember knowing you (as far as this site counts as knowing anyone), is not bug; it's a feature. "Official" timelines change, not because the team changes their mind, but because they embrace the different points of view on the subject. Calling for a definitive, solid, timeline is not calling for clarity, but calling for the art/intent to be fundamentally changed.
