Hylian Alphabet in Breath of the Wild

I was watching the recent treehouse stream, and noticed that there was a [distinct Hylian alphabet on the stable](http://imgur.com/a/lbBhD), different from the Sheikah text we have seen everywhere else. As I don't really pay much attention to mobile games, I didn't really recognise it, but /u/Ymcan64 pointed out that it's the exact same alphabet used in _A Link Between Worlds_.

What implications, if any, does this have of the timeline placement of the game?
