China shows why this is impossible.
When people propose switching to UTC what they are actually proposing is that everyone nominally switches to UTC but still uses local time informally in everyday life, which is a worse system than time zones. At least with time zones there is a way to know what time it is in any given place. With informal time you lose that.
how so?
Eastern parts of China gets up at 05:00 AM and westtern part gets up at 10:00 AM.
People get used to it.
Local time tells you things like "when is it a good time to call this person". Unless the person is calling is in China.
