I'm a little leary about some of the time frame here- especially early on, with the one year difference between major events, though I see that those numbers are kinda just place holders for dates that aren't going to be able to have numbers.
There are some others that seem to have weird dates too- the only one that I noticed right off the bat was the date that Darkwood joined the Prolongers. I doubt that it was only a year before he came to the Cage, and I had the sense that he spent years traveling the planes before hand.
Time of Troubles set at +118 would make Attack of Myth Drannor etc be 10 years earlier (Checked through A Grand History of the Realms).
Drannor should fall at -548, be assaulted at -550.
710 DR (listed as -540 Sigil)
1358DR (Time of Troubles is listed at +118) do the math..
710 + 540 + 118 = 1368. Years do not add up properly.
Myth Drannor nearly falls to the Army of Darkness in 712DR (see source below)
Myth Drannor Actually fell at 714 DR (WTC11836)(TSR1085a)(A Grand History of the Realms),
I dunno the timeline seem really too short. Not the ages and ages that planescape should have with more forgotten than remembered, and more remembered than could ever be known to any mortal.
One thing with the source for this information is you have to look at the context and In-Character Source of it to see how trustworthy it is.
Given the source of the earliest material I'd say the idea of the yugoloths forming first is more an idea of the yugoloths and not perhaps a real fact.
I agree with Ohtar. The yugoloths are created only one year after the baernaloths come into being? That's fast work!
Much more than two hundred years passed between the casting of the Labyrinth Stone and Shekelor's expedition. Shekelor only found a hint of the event, in a scroll ancient even to him.
The fiendish teleportation ability is, if I remember right, based on an aasimon the 'loths imprisoned, so that must have been invented after the creation of that celestial type.
The Great Modron March should be listed before Dead Gods, and Primus was slain before either.
"Torment" definitely took place before the Faction War, as the factions are doing fine. It probably happened around the time of the Factol's Manifesto or slightly thereafter.
