> If you're planning to call someone far away, picking a time "during work hours" becomes very difficult without time zones.

Does everyone in your office work the same hours?

We _already_ have the problem of "What are Bob's work hours" because most office workers don't work the same hours. Some folks come in early, some work late -- some come in late and leave early.

That has been common for decades and has become even more pronounced with increased remote work, particularly across time zones.

We shouldn't build our society around a myth of 9-5 office workers.

I'll add that for serious scheduling, people use digital calendars extensively. Some sort of "work hours" would need to be marked on those, but everything else would be simpler.
