1994 - X-men, X2 and the Last Stand all take place around the year of 1994, within a couple years (1993-1997), stated by Professor Xavier to Logan in X-men, "Logan, it's been almost 15 years hasn't it? Living from day to day, moving from place to place, with no memory of who are what you are."
Also stated by William Stryker in X2, "Wolverine? Well, I must admit, this is certainly the last place I'd expect to find you. How long has it been? Fifteen years? You haven't changed one bit. Me on the other hand--nature."
15 years from 1979 is 1994. There is a reason it says "not too distant future" and not a specific year, they knew they didn't want to be specific in case they needed to slide the time period. 1979 is the year Wolverine lost his memory, the year Three Mile Island had the meltdown in Origins: Wolverine.
