The prologue to TWW clearly tells that it takes place in the timeline as when OoT Link defeated Ganon in the future. Furthermore, this Ganondorf recognizes WW Link's green tunic and hat, and went to great lengths to seal the Master Sword, proving that he fears it's power, having remembered it from the past, when he was first destroyed by it.
In TP, sages who are not the Sages awakened by Link in OoT put Ganondorf on trial and (attempt to) execute him, and then send him to the Twilight Realm. During the game, Ganondorf says nothing at all about either TP Link's clothes or the sword he wields, which he surely would have had this been the same Ganondorf that had fought the adult Hero of Time only about a century earlier. From this, the most logical conclusion is that TP Ganon is not, in fact, the same Ganondorf that adult OoT Link defeated, and that he is what Ganondorf would have become if Link had never opened the Door of Time.
ALttP's history meshes much more easily with TP's version of the sages and Ganondorf than with OoT's (though Ganny was revived at some point between TP and ALttP, presumably in TP's upcoming sequel). Therefore it logically follows TP for the time being.
LA could be in two spots. There are those who believe it is ALttP Link (which is supported by the fact that LA was created after ALttP, while the series' timeline was still fairly straightforward, and by how Zelda games come in pairs, and LA pairs off with ALttP), and there are those who believe it comes after the Oracle saga.
ALttP was expressly a prequel to LoZ, so LoZ must follow ALttP in the same timeline. AoL is an express sequel to LoZ, so must follow it in the same timeline.
Phantom Hourglass is an express sequel to TWW, and so must follow in it's timeline.
The Oracle games enclose themselves, and so can be inserted at any point after which Ganon has been killed.
The Four Sword games are known to be far in the past to the rest of the series, but so far have no true connections and thus are currently in a timeline of their own.
