I disagree. We're inundated with time displays. Right now I have 5 time displays within 20 feet (computer, stove, microwave, phone, watch). I could imagine some people would continue to reference sundown / sunup for relevant situations (kids, get home by dark) the same as they already do, but not for anything time sensitive (like say a meeting). There's just no way I would schedule a call for "3 hours past sunset" even if I was forced to tell time in binary.

You're incorrectly generalizing from yourself to most people. Most people think in local time and would continue to do so regardless of whatever you attempt to do to impose something else on them. Also, think of how deleterious the abolition of local time would have on communication. Right now I can say something like "I received an urgent call at 3am" and you know immediately what that means. But if I said "I received an urgent call at 17:00Z", a lot of the meaning is lost. You'd have to know where I live, i.e. what my local time zone is, and then do some quick mental math to determine what actual time of day 17:00Z means for me. With local time, that calculation is already done for you! Local time is just too damn useful of a concept. It really truly is better than global time for most uses. Global time is really only useful for scheduling global meetings and computer stuff. Even within the US, all of our scheduling is done by US timezones.

  If you said you received an urgent call at 17:00 I would know exactly what time that is... 17:00. No meaning is lost because there is no time zone (local time) and therefore no disconnect / mental mapping / conversion required. Given your example we must be talking about different things. I'm saying ONE time globally.

    I think he's trying to find a case where the absolute hour (1700Z) is less relevant than the subjective hour (0300 local means he was dead asleep)

      Exactly. The point is that it's happening in the middle of the night. That context is entirely lost without local time.

But if I said "I received an urgent call at [3am]", a lot of the meaning is lost.

    It's almost like both are useful for different things, and you're not gonna have any luck forcing people into one or the other for everything. Also, I don't understand what point you're making. The square bracket stuff you've added doesn't work. You haven't managed to correctly communicate the fact that the person was woken up in the middle of the night. Which is what local time is extremely good at and global time cannot do -- putting a specific time in context with the rhythms of the day. Which, you know, is very important for most normal communication. I can't even schedule a worldwide meeting using global time; I have to use the local time of each participant individually to figure out what the best time is that maximizes the # of people calling in during the workday and minimizes the # of people that need to be up in the middle of their local night.
