Time zones acknowledge that everyone synchronizes with the people around them, possibly with some added information about people who are theoretically too far away to be in the same time zone together but still want to synchronize with each other. (This gets really absurd in the Pacific, but every time zone has odd jogs.) Removing time zones won't make that synchronization stop happening, it'll just make it more difficult to predict which clock distant people are really keeping in terms of when they're up and active and doing business.
