| > Things like "open on Wednesdays" will cease to have meaning They already don't have that much meaning and we still communicate fine enough. For instance a dance club open on Saturday nights probably closes on Sunday, but nobody is troubled by the imprecision. It might even actual open on Sunday at 00:30, but still advertise it as Saturday night 24:30. Same for restaurants that stay open late enough. Or convenience stores, gas stations, theaters, gym clubs, barbers, tv shows etc. You're right that for centuries the notion of "a day" was structural to everyday life. Most countries are past that point. > Alice still needs a translation table to figure out what the meeting time means for Bob. Why doesn't she ask Bob ? Isn't he the one who understands when his kids are back from school, when does the grocery store close, or if he has a 2h slot right after the sun rises where he can focus on Alice's project, or he needs to be at the office that opens at 8AM. In my view, knowing that "10 AM in Sidney is roughly a few hours before the zenith"
helps very little in practical matters. The information is way too vague and out of context to be usable. |
