While I agree in spirit and think that was true for most of the games when written, there has been an official timeline published by Nintendo[1,2] since 2011 (and the idea was apparently around internally since 2002).
I would be surprised if it did not have some impact on the writing of the games, though of course there is (as of yet) no explicit reference to the timeline in the games.

Sure but the Nintendo timeline is just another retelling of the legends of Zelda, an unreliable meta story of a past (or future) that is lost to time
