Cox has a unique distinction in the series. He is the only guest
star who ever did a “captains log” entry when his captain was in
charge of the Enterprise while Captain Picard was on a mission.
This occurred in the episodes “Chain of Command”.
Roddenberry and some other people locked themselves in Gene’s
office for about 45 minutes to figure out what Stardates mean.
In that 45 minutes, they came up with a coherent setup on how
Stardates are used, and what they mean.
1988 episode “The Neutral Zone” was a milestone in the history
of Star Trek by establishing that the first season of The Next
Generation took place in the year 2364. This was the first time
an exact calendar date was provided for a Trek episode. All Star
Trek episodes, chronologies, novels and background information
since 1988 have been calculated from this date.
