How does it solve anything?

If everyone was on UTC and I want to schedule a meeting with my coworker across the country, I still need the application to tell me what time standard business hours are wherever he is located

So the developer still has to do the UTC->Localtime lookup.

Plus, when I travel, I have to keep a chart of local "human-time", so I know that when it's 03:00, it's time for lunch.

You always have to ask the question "what times are good for you?" because everyone lives on a different schedule.

With global UTC it just means the times each of you give don't need to go through a complicated conversion process to interpret.
