In TP you find the Master Sword in the woods.
In ALTTP you find the Master Sword in the woods,which tells me that ALTTP takes place on the same timeline.
Miyamoto said that way before Wind Waker came out.
The evidence is everywhere in WW.
Hyrule is a forgotten kingdom in WW,in fact no one even speaks the language.
The Imprisoning war and ALTTP can't take place in the Adult Timeline.
ALTTP would have to take place after WW in a new Hyrule where they would have to be up on there history of the old Hyrule's legands.
Lgands and history that the Great Flood would have wiped out.
