When the Okudas came out with the chronology in the 90s, they placed TWOK and TSFS in 2285. They said it was conjecture with no explanation on how they determined 2285 for these films.
How did they come up with this year? The Okudas say Space Seed is in 2267 which is 18 years prior to TWOK in their chronology. Khan mentions in TWOK that its been 15 years, so shouldn't these films be in 2282-2283?
Anything I've read since the Okuda chronology uses the 2285 year for these two movies. As far as I see it, there is nothing on film that points to 2285. Any idea how to quantify 2285 for these two movies?
