A Heated Time Zone Debate

Ok so today in class we did our time zone debate. As we ended our discussion I'm leaning more towards the side that we should keep time zones. I do see the benefits in abolishing time zones but, I think it would just be more practical to keep them. Because the world is already using time zones it would be hard to get everyone to get on board with the idea of abolishing them. Even if we were to abolish time zones and have a 24 hour clock, the sun would still rise/set for different parts of the world so it's kind of pointless.
