> Uncle Steve is zero hours ahead.

Uncle Steve is the same number of hours ahead that he has always been, and that's a thing that could be looked up just as easily as finding his time zone. I think the author is greatly exaggerating the degree to which time zones solve any of the problems mentioned. Uncle Steve might be on a different sleep schedule from me, regardless of whether or not he's in a different time zone.

Days of the week definitely become interesting in a global UTC system, but noon used to literally mean "the sun is at it's highest point". I suspect that people would grumble for a year or two and then forget that another system ever existed.

There's certainly a bit of dramatization/exaggeration here, but the main point is that it doesn't really fix the stated problem while also being a huge change for everyone to adapt to.

I feel like days are a non-issue; they would just start at different times (UTC) in different territories. This wouldn't make things any more complicated than they already are (currently, if I want to talk to someone in Australia, I have to look up what time it is in Australia and infer the day of the week from that, if necessary. If everything is under UTC, I know what "time" it is, but I still have to look up what day it is).

Most of the issues time zones cause are not "day of the week" related anyways (at least in my experience), so I think having to figure out what day of the week it is somewhere else wouldn't be a common problem anyways.

I think you missed entire point of operation.

If everywhere runs on UTC, they will still have different times when people are working/not working/sleeping so you still have to look something up and figure it out.

With time zones, you look up "What time is it?", realize it's 4:30AM and since most people around the world follow similar schedule, you quickly realize he's fast asleep.

Also time references in stories would become much more cumbersome, and never mind how you'd handle fictional locations…
