Let's imagine we have no time zones and the article is trying to make fun of introducing them. Before introducing time zones I want to call my Uncle Steve in Melbourne. When does the evening start there? Google tells me it's 8:00. Better not call right now. After introducing time zones I want to call my Uncle Steve in Melbourne. When does the evening start there? It's 20:00, same as it is here, of course! Same as it is in New York, Bangalore and Hawaii, at the South Pole and on the Moon. Well, hold on a second. First of all, we need to straighten out some terminology. What does 20:00 mean exactly? It's strongly deprecated now, because now it refers to the position of the Sun, not of the clock. And then it goes on like this for 5 pages... Imagine we had universal time across the globe and someone tried to introduce time zones. It would seem like a batshit crazy idea to everyone.
