In the mid-19th century, local time was still based on a sundial.
But railroads started carrying folks around and telegraphs magically connected them across continents. People needed standardized schedules to catch a train or get a message http://trib.al/rUCaREo pic.twitter.com/Z0ZV4vOT6m
So, in 1884, international time zones were agreed upon. The prime meridian runs through the Royal Observatory in Greenwich, London. The rest of the world was divided into strips of 15º longitude in width, adding up to 24 zones, 1 for each hour of the day http://trib.al/rUCaREo pic.twitter.com/JJCOktjrK8
But, once the system was devised, politicians everywhere started messing with it:
The French for years refused to accept the British standard
In the decentralized U.S., time-keeping remained a free-for-all until 1918 http://trib.al/rUCaREo pic.twitter.com/bPCbH3dLfT
Even now, nations bend the meridians to suit their ideologies:
North Korea shifted its time zone by 30 mins, because it could, before moving it back again
Nepal diverges by 15 mins
Russia has 11 time zones
China, which should have five, has one

Politics isn’t the only thing that exposes the system as intrinsically silly. If you ever visit the right spot in Antarctica (where the meridians converge) and stretch out in your sleeping bag, you’ll be in all time zones simultaneously http://trib.al/rUCaREo pic.twitter.com/Ctc2tcZ33r
Besides being inane, the convention messes with our biological clocks. People who live on the eastern edge of a time zone get their circadian rhythms, and health, thrown out of whack http://trib.al/rUCaREo pic.twitter.com/AsnJGQHS96
The whole notion of time zones rests on a fundamental delusion. It suggests that a number — 7, 12 or 21 — should tell us when to get up, eat lunch or go to bed. We should instead be taking our orders from the interplay of the sun and circadian rhythm http://trib.al/rUCaREo pic.twitter.com/FDdHNQRIHT
Hence we should transition to a simpler but superior system, combining:
One global time
Several billion individual and biological times http://trib.al/rUCaREo pic.twitter.com/RXhaxbrN38
The single global time is necessary in our truly global Zoom-and-Slack era. Pilots, who’d rather not crash in the multinational airspace, already use Coordinated Universal Time or UTC -- the successor to Greenwich Mean Time (GMT) http://trib.al/rUCaREo pic.twitter.com/T22sAamuLf
Initially, having one global time would be weird, even hilarious. New Yorkers would have to get used to having breakfast when the clock seems to say noon, Shanghainese when it shows midnight. But we’d quickly sort it out http://trib.al/rUCaREo pic.twitter.com/OeWKYnNOjB
In the same way, after adopting UTC everywhere, we might also reconnect with natural time. We’d start listening to our bodies again, and associate different numbers with dawn, noon, night and so forth http://trib.al/rUCaREo pic.twitter.com/P5pzDPdtlh
It might even bring us some benefits, by forcing us to rethink conventions:
School might start later to suit teen brains better
Work should finish before dark so the blue light of our screens wouldn’t mess with our sleep

Making time in one sense absolute would be efficient in our global economy. Leaving the interpretation of that number up to us could help re-synchronize us with natural light, aiding everything from digestion to sleephttp://trib.al/rUCaREo
