Re: Time and Date?
You don't have to know what zone you're in to just say how long you're going to be gone, in the cases where people really need to know that closely. And "Back in five!" is a whole lot easier on everybody than, "Back at...OK, let me see, that'll be eight o'clock my time, so that's...fifteen, but not everybody does 24-hour time, so...3 PM, GMT!" And then everybody else has to go and back-figure it to their own zones. With "Back in five!", nobody even has to know where in the world they are. You could blindfold me, fly me anywhere in the world, and I could still estimate a relative return time. (But, er, don't. People would come looking for me. Honest, they would.)
I'll agree that not everybody thinks of it all the time, but I can hardly imagine that somebody's not going to think of that, yet take the time to look up their timezone, find the GMT-time even if it's on the main menu, and figure out what their return time is relative to that.
So, happily, I don't even have to look past my nose for this. But, er, Jase? What's wrong with my nose? Is there a smudge, or something?
