The "timeline" was a big debate in the Zelda fandom/community for a long time until the Hyrule Historia book introduced an "official timeline" that featured a split three-way timeline centered around Ocarina of Time as the source of the split. That was released after Skyward Sword. Breath of the Wild had some discussion about where it fits but wasn't really seen as too big a deal, then Tears of the Kingdom all but straight up ignored the "timeline" and introduced a new "canon" founding of the Kingdom of Hyrule, which while I've long stopped paying attention to the fandom, I could imagine the timeline debate starting all over again. TLDR: some people take video game lore really seriously.
As a proud owner of that wonderful book, I get it. But people need to chill; trying to stick to a chronology, an IP almost 40 years old, seriously? That shit would prevent the series to reinvent itself. I think it's for the best if we all forget about that. It was nice for a while, tho.
