Re: Star Wars The Clone Wars Season Five News and Discussion
Just look at the very first season of TNG. In "Encounter at Farpoint" Data says he's from the Starfleet Academy "class of '78" whereas later episodes clearly set the first season of the series during the year 2364 and Data's discovery on Omicron Theta taking place in the year 2338.
