Personally, I'm not really sure what information there is. Certainly it's clear it happened relatively recently, as during the funeral for Aillil (who died during the uprising) Cahir was ten years old and he's around 25, certainly no older than 30 in the Saga, around 1267 to 1268. Also Dacre Silifant and Ola Harsheim both served in the Nilfgaardian force sent to supress the Uprising, and that army was commanded by Markus Braibant.

I'm presuming it was just one significant uprising, since all references seem to refer to one event (instead of them saying "the first uprising in Nazair" or "the Nazair uprising in the year XXXX"). It'd definitely fall under the Nilfgaardian push northwards that set the Northern Wars into motion (starting 1239). Taking all the above into account and given how far northwards Nazair is (meaning all lands below would have to be conquered first) it probably happened around late 1240s/early 1250s as a rough estimate.

Beyond that, I'm not sure if anything else is mentioned. I'll have a look though.
