My revised timeline

I assume you meant to say 'what do TRR and AST stand for?'

TRR = Frehsly-Picked Tingle's Rosy Rupeeland

AST = Ancient Stone Tablets

You can find a list of abbreviations here.

I hope that's helpful...

Hmm, I doubt either of those are meant o be official Continuity, why not also include Link's Crossbow training.

There are many different fan made and disputed cannoncity games... As for TRR it doesn't have to be in the timeline, but it can be placed on it to help hold things together. AST probably isn't canon, however it can help to explain aLttp/LA a little bit! Most people don't include these, and the same is the for LCT, but some people do put it in the timeline. It doesn't really matter though!
