Concerning Ben Topin: I noticed. No complaint, but I noticed. The idea that your viewers didn't notice is bizarre.
Concerning night and day on earth: The interpretation of the statement is bizarre, since it's always every hour of the day somewhere earth. I understand that comment to mean that the Enterprise followed a 24 hour day, with 'time off' following the idea of night and day on earth, rather than the human clock which is not exactly the same as the 24 hour day. People living in dark caves cut off from the cues of the outside world do not follow a 24 hour day. Right now Kirok L'Stok is in the early morning hours of March 1, while I am in the late afternoon hours of Leap Day. It's not even the same DAY everywhere on earth, for Pete's sake. There would be no logical reason to undercut efficiency in deep space during certain hours by declaring they are to be 'night' for the whole ship. Everyone can work during their own day, every shift. Falls into the whole, "Why I am not such a great Trekkie" class of statements. I like Trek, I love Trek Fans. I'm a Trekkie Fan!
And yes, I live in New York City... I can order a breakfast or dinner at any hour of the day or night. It would only make sense that a large Starship never sleeps...
