What If... Time zones didn't exist? | What If

Daylight saving time means we change the clocks twice a year, and the world has over 30 different time zones. Some countries span multiple different time zones, while the likes of China and India choose to have just one time zone despite the huge differences in real time from east to west. Time influences almost every aspect of our lives – yet we barely ever stop to think about what time means exactly. Studies show the Daylight Savings Time leads to spikes in heart attacks and traffic accidents, while reduced sleep due changing times is linked to increased levels of obesity. So, why do we even bother? That's the argument of some scientists, who believe the whole world should switch to Coordinated Universal Time (UTC), which is already used in aviation and in space. In this video we ask, what if we abolished time zones (and clock changes) forever? This video was produced as part of Digital Society, a publishing partnership between WIRED and Vontobel where all content is editorially independent.
