I think time zones should be eliminated and that the whole earth should use one central time. CMV.

In the past all cities used their own time. So even cities that were quite near to each other could keep time that differed by 10 minutes for example. Starting from the 19th century, we began to use time zones. (Mainly to make it less confusing to travel with trains. The world got smaller.) The next logical step, I think, is using the same centralised time for the whole world.

The internet has made the world very small. We can travel to the other side of the world in a day. Having time zones in the modern times is just confusing. Having a centralised time for the whole earth wasn't logistically possible in the past, but it is now.

Yes, it's perhaps a bit weird at first to wake up for work in the "morning" at 17:00, but after a few months I'm sure this feeling will fade. The advantages are greater than the disadvantages. Or are they not?

Change my view.

A large number of mental models and systems are based on a common experience with time. Everyone wakes up at the same time and goes to bed at the same time. Jobs are 9-5. Prime-time TV is 5-9. Hours of operations for most buildings are the same. If you get rid of time zones, then this order is shattered. Every single city across every nation would have different workplaces deciding when work would start and end. Schools would have different start and end times. This would cause a lot of confusion for locals. If you are traveling then you will be completely and utterly lost. Let's say you travel from NYC to LA. Now you will be unable to figure out when shops close, work starts, rush hour is expected, etc. without looking up each one individually.

This also skims over the massive costs in switching over to a new system.
