Since humans still prefer to work in daylight and sleep in darkness, even without timezones you still need to have extra information in addition to "what time is it" to figure out if Steve in Australia will be awake at @700 or asleep...

Maybe when the nuclear winter makes it dark all the time, or forces us all to live underground, then we can abolish timezones.

To be fair, I still have to look up what is the time zone difference to Australia and do mental maths, which is the exact same effort as looking up whether @700 is day or night time over there.

Aren't we saying the same thing?

On second thoughts, the extra information is probably less complicated, Steve can say "I'm available between @300 and @1000" (maybe he keeps odd hours), and this knowledge plus a glance at the current time can tell me whether I can call Steve.

Steve could also just tell his availability in UTC, and the same lack of maths is needed. Although, we still need maths because most of us don't use UTC time, in the UK only half a year as well. Except Icelanders...

Good luck convincing Aussies, Kiwis and Americans to share their times in UTC without having to ask or doing the conversion yourself.
