The Indictment
Time zones, as currently implemented, are a system of 37 parallel realities coexisting on a single planet. Not 24, as a reasonable person might assume — 37. Because the International Date Line has opinions, half-hour offsets exist for reasons no one alive can explain, and Nepal chose UTC+5:45 out of sheer defiance.
For thousands of years, the sun was the best clock available. A stick in the ground, a shadow on a dial — that was the state of the art. Time was local by necessity because the only reference point was the sky overhead. Noon meant the sun was at its highest. Midnight meant it wasn't. Every village had its own time, and that was fine, because nobody needed to coordinate with a village 500 miles away.
Then came the railroads. British railways were the first to feel the pain — by the 1840s, they had largely standardized to Greenwich Mean Time just to keep schedules coherent. Across the Atlantic, hundreds of American cities still kept their own local solar time. Pittsburgh was 20 minutes ahead of Columbus. When a train schedule said "arrives at 4:00," the obvious question was: whose 4:00? Trains were crashing. Passengers were stranded.
The solution came from multiple directions at once. Sir Sandford Fleming, a Canadian railway engineer, proposed a worldwide system of 24 standardized time zones as early as 1879. American railroads unilaterally carved the continent into four zones on November 18, 1883 — "The Day of Two Noons." And in 1884, the International Meridian Conference in Washington D.C. brought 25 nations together to establish Greenwich as the prime meridian and lay the groundwork for global time standardization. By 1929, most countries had adopted the system.
Meanwhile, the science of timekeeping moved on. Quartz oscillators. Cesium atomic clocks accurate to one second in 300 million years. GPS satellites broadcasting coordinated universal time to every device on Earth. The ability to measure time has advanced by orders of magnitude — and yet the system for displaying it remains anchored to the sun. The same sun. The same shadows. The same ancient instinct that noon should feel like noon and midnight should feel like midnight.
That instinct made sense when sundials were cutting-edge technology. It makes considerably less sense in a world where a server in Virginia processes a request from a phone in Tokyo, timestamps it in a database hosted in Ireland, and sends a confirmation to an inbox in São Paulo — all in under 200 milliseconds. The sun is irrelevant to this transaction. The clock should be too.
The Cost
The cost of maintaining the timezone system is not merely inconvenience. It is measured in engineering hours, in bugs, in money, and in the slow erosion of sanity among those who maintain software that must operate across borders.
The IANA Time Zone Database — the canonical source of timezone rules for virtually every computer on Earth — is maintained by volunteers. It is updated multiple times per year because governments keep changing the rules. Morocco once changed its DST schedule four times in a single year. Russia has abolished and re-adopted DST multiple times. Samoa skipped an entire calendar day in 2011 to jump across the International Date Line.
Updating a clock is trivial — operating systems handle that automatically. The real cost is in the business logic built around the clock. Every application that schedules, bills, reminds, expires, or recurs must account for the fact that users exist in different time zones and that those zones shift unpredictably. "Send this notification at 9 AM" means writing code that knows what 9 AM means for every user, in every zone, on every day of the year — including the days when some zones jump forward, some jump back, and some do nothing at all. That logic is where the millions of developer hours go.
And yet the world accepts this. Accepts it because nothing else has ever been known, and because the alternative seems unthinkable. This manifesto exists to make it thinkable.
The Proposal
Picture a world that operates on a single, universal, coordinated clock. No offsets. No conversions. No "well, it's 3pm here, but what time is it there?" Just one time. Everywhere. For everyone. Always.
All clocks, worldwide, shall display the same time. Whether this is called UTC, Universal Time, or something more inspiring is unimportant. Suggestions are welcome. "Earth Time" has been proposed.
Local schedules shall adapt to Earth Time, not the other way around. If your business hours in Tokyo are 01:00 to 09:00, so be it. The numbers on the clock are arbitrary. The sun does not care what your watch says.
Daylight Saving Time shall be immediately and irrevocably abolished. No phase-out period. No grandfather clauses. It ends. The clocks do not move. Ever again.
Any software function, API endpoint, or database column that currently stores, converts, or displays timezone-adjusted time shall be simplified or decommissioned. Entire categories of bugs will cease to exist. The IANA Time Zone Database will become a historical document, like the Rosetta Stone — fascinating, but no longer necessary.
Time shall be represented exclusively in 24-hour format. AM and PM are relics of a sun-based system — "ante meridiem" and "post meridiem" literally mean "before midday" and "after midday." When the clock is no longer tied to the sun, the concept of midday as a fixed point loses all meaning. 24-hour time is unambiguous, universal, and already used by aviation, medicine, and the military. The rest of the world can catch up.
Objections and Rebuttals
Resistance is anticipated. Humanity has been dividing the Earth into temporal fiefdoms since 1883. Below, the most common objections are addressed with the seriousness they deserve — which, to be clear, is very little.
But people need the sun to be up during the day!
They do. And it still will be. Earth Time does not move the sun. It changes the number on the clock when the sun is up. If sunrise in your city happens at 22:00 Earth Time, you simply know that your day starts at 22:00. You already know that "lunch" is at different clock-times depending on your culture. In Spain, lunch is at 14:00. In Japan, it's at 12:00. Did Spain collapse because their lunch number is different? No.
The association between "12:00" and "noon" is arbitrary. It is learned, not innate. Children in a universal-time world would learn their local "daylight hours" the same way they currently learn that bedtime is at 20:00 — by being told.
But farmers need Daylight Saving Time!
No, they don't. Farmers have historically opposed Daylight Saving Time. This is one of the most persistent myths in the timezone discourse. DST was introduced for energy conservation during World War I, not for agriculture. A cow does not understand what a clock says. A farmer wakes up when the work needs doing, regardless of whether the government has decided to shift an hour.
The farming argument is so thoroughly debunked that continuing to make it should be considered a misdemeanor.
It would be too confusing!
More confusing than the current system? The current system where a flight from Los Angeles to Sydney crosses the International Date Line and arrives two days later despite being in the air for 15 hours? The system where you can fly from Samoa to American Samoa — a 30-minute flight — and arrive yesterday?
Right now, scheduling a meeting across three time zones requires a timezone converter, a calendar that understands DST transitions, and a willingness to accept that someone will inevitably show up an hour late. Under universal time, you say "15:00" and every single person on Earth knows exactly when that is. The confusion argument is not an argument against universal time. It is the strongest argument for it.
Midnight should be at midnight! Noon should be at noon!
Says who? China — the fourth-largest country on Earth, spanning five geographical time zones — operates on a single time zone. Has since 1949. The sun rises in Kashgar at roughly 10:00 Beijing Time. The population of Kashgar has not descended into temporal chaos. They simply know that their morning starts later on the clock. If 1.4 billion people can handle one time zone, the other 6.6 billion can manage.
This would never be adopted. It's too radical.
The metric system was radical. Decimal currency was radical. Abolishing the Julian calendar in favor of the Gregorian calendar was radical — and that transition was so messy that some countries didn't adopt it until the 20th century, resulting in the October Revolution actually happening in November.
Every major improvement to how humans coordinate has been called impractical until it was implemented, at which point it was called obvious. This manifesto simply asks to be ahead of that curve.
But my culture's traditions are tied to specific clock times!
Traditions are tied to events, not numbers. "Dinner when the sun sets" is a tradition. "Dinner at 19:00" is a convention. If sunset in your city moves to 02:00 Earth Time, the tradition is perfectly intact — dinner happens when the sun sets. The number changed. The tradition didn't.
Ramadan already follows a calendar entirely disconnected from the Gregorian clock. Jewish Shabbat begins at sunset, not at a fixed time. These traditions survived the introduction of Standard Time in 1883. They will survive this too.
A Final Word
The world will not change overnight. Time zones are deeply embedded in law, in infrastructure, in the human psyche. Abolishing them would require international cooperation on a scale that humanity has rarely achieved.
But it has been achieved before. The meter. The second. TCP/IP. A man on the Moon and back, using a computer with less memory than the device displaying this page.
Agreeing on what time it is should not be this hard.
Until that day, developers will continue to file bug reports and stare at timezone conversion charts with the hollow expression of people betrayed by a system they did not choose and cannot escape. But silence is no longer an option.
