Then when you visited different parts of the world, not only would you need to know that the seasons might be in different months of the year, you would also need to know that people worked different hours.
This might actually help with jet lag. If you go on a virtual reality ride where the movement of your seat is not correctly synched to the movement on the screen you will tend to get sick.
It could be that when we go somewhere else and are constantly told "It is 8am and we should be wide awake" but we just came from somewhere where it was 5am and we want to sleep in a bit more, that we suffer something similar.
If everywhere we go it is the same time then we will at least intellectually know when we should be tired and when we should be awake, and then only have to decide to gut it out when necessary.
Nah, people would still synchronize their world to their local sun. I’m not going to work at 1 in the morning because we decided GMT is the time, I’d be going to work at 3PM which oddly enough would look just like 8AM did before.
It’s called Zulu time. Or Greenwich Mean Time. If we’re a global community then we’ll all be on the same time.
I’ll call you at 6AM means you call at 6 anywhere in the world regardless if it daylight or nighttime.
Seems to work okay for the military.
