Forum:KB:SWTOR dates

So I've been playing Star Wars: The Old Republic. I've decided to have a quick look at some Wookieepedia articles about it, and saw something odd about the dates. It seems that articles are written assuming Chapter 1 takes place in 3,643 BBY, Chapter 2 in 3,642 BBY, and Chapter 3 in 3,641 BBY. Most of the sources for dates are just referring to the game. But in the game, there is no indication that the events are spanning years. The game barely mentions the year at all. So I'm wondering where this info came from.
