- There is some controversy over the dating of Star Trek: The Motion Picture. The earliest the film could take place is late 2272 (based on information from VOY: "Q2", which stated that Kirk's first five-year mission ended in 2270, and information within the film that Kirk had not "logged a single star hour in two-and-a-half years." The latest the film could take place is 2277, since the Star Trek II: The Wrath of Khan style uniforms are in use by 2278. (TNG: "Cause and Effect"). Pocket Books officially places the film in 2273.
