Let's invert the argument:

Using UTC only:

I want to call my Uncle Steve in Melbourne. What are the working hours there? Google tells me it is currently 7:00 to 15:00 there. It's probably best not to call right now.

Using the current system:

I want to call my Uncle Steve in Melbourne. When are the working hours there? It's 8:00 to 16:00, same as it is here, of course! Same as it is in New York, Bangalore and Hawaii, at the South Pole and on the Moon.

You get the point...

That latter example is pure nonsense - it's the situation today, and that's not how we do it today.

Realistically, both ways you're using a table you looked up online. What's the advantage of one chart over the other?

Of course not. If everyone uses UTC, Melbourne wouldn't start they working hours at 8 UTC, neither would you (unless you are in a place where 12pmUTC is sun-noon). So you would need to either ask him his hours, or convert anyways
