Time confusion in the 20th century

Even with fewer time zones, time confusion arose again in the 20th century. Air travel, the internet and mobile devices gave us a 24-7 culture in which we're tightly interconnected to events in other parts of the world.

Another solution was proposed: Abolishing time zones and putting the entire world on universal time (UTC). Under this system, it's 9:00 everywhere on the planet, even if it's morning in one place and evening in another.
