You still have to maintain all of the same information. Keeping track of the local solar time for cities, countries, and regions. Also, consider what it would be like to travel to other time zones. Not only do you have to learn of the UTC offset for the local region in terms of the time of day, but you have to keep remembering it constantly for everything you do throughout the day. So now, if you're living on the East Coast and you want to get up at 8am local time you need to set your alarm to 12pm UTC instead. But when you travel to Hawaii you need to set your alarm to 6pm UTC. And now every single one of your waking days is distributed across two days with the day change happening at local 2pm in the afternoon. Your work week is Monday through Saturday, your weekend is Saturday through Monday. I do not understand why anyone ever thinks this insanity sounds like a good idea.
