Earth is a terrible roommate. It cannot keep a schedule, its rotation is constantly dragging due to tidal friction, and it expects us to accommodate its sluggishness by adding random, chaotic extra seconds to our year. But the tech industry has finally had enough. No leap second will be introduced in December 2026, marking the beginning of a messy, decade-long divorce between the way our planet spins and the way our servers count.
We have decided that if the universe does not align with our network protocols, then the universe is wrong. By 2035, we are officially freezing the alignment between Coordinated Universal Time (UTC) and astronomical reality. We are choosing the database over the sun. It is the most human decision we have ever made.
The astronomical equivalent of a pocket dial
To understand how stupid this situation is, you have to realize that a second is no longer defined by the Earth. Since 1967, a second has been defined by the vibrations of a cesium-133 atom, which is incredibly reliable and doesn't get distracted by the moon. The Earth, meanwhile, is an wobbling rock covered in sloshing oceans that slows down whenever it feels like it.
To keep our hyper-precise atomic clocks in sync with the actual position of the sun, metrologists invented the leap second in 1972. Since then, they have forced us to insert 27 extra seconds into our history. It is the astronomical equivalent of hitting the snooze button, except instead of sleeping in, we are forcing billions of machines to pause and ask themselves if reality is glitching.
Imagine explaining this to an alien. "Yes, we have mastered atomic physics, but we must occasionally pause our entire global communications network for one tick because our dirt-ball is heavy and tired."
The night Cloudflare fell down the stairs
If you want to know why engineers hate the leap second, look no further than the trail of digital destruction it leaves behind. Computers do not comprehend a minute with 61 seconds in it. To a database, a minute has 60 seconds. If you show it a 61st second, it does not say "ah, a bonus moment to appreciate life." It panics, consumes 100% of the CPU, and passes out.
During the leap second of June 30, 2012, Reddit, Yelp, and LinkedIn all crashed simultaneously. Qantas Airways' entire booking system went down, forcing staff to write boarding passes by hand. In 2016, Cloudflare went sideways because their software calculated that time was moving backward.

Engineers tried to fix this with "leap smearing," which is a real industry term that sounds like a cream cheese accident. Google and Meta literally stretch the seconds across an entire day, making every second on June 30th a tiny fraction of a millisecond longer. We are literally warping the fabric of perceived reality just so some PHP script doesn't throw a tantrum.
The great atomic standoff of 2035
This brings us to the political thriller currently happening in the sterile offices of the International Bureau of Weights and Measures (BIPM). In late 2022, they voted to suspend the leap second by 2035. This was not a peaceful negotiation. It was a bureaucratic cage match.
Russia voted against the proposal because their GLONASS satellite navigation system relies heavily on astronomical time, and changing it requires them to basically rebuild their space infrastructure. The UK, historically obsessed with Greenwich Mean Time because it makes them feel like the center of the world, abstained. But the tech lobby won.
We are now on a path where UTC and Earth time will drift apart. By the time we reach the year 2135, our clocks will be about a minute out of sync with the actual position of the sun. Our great-grandchildren will have to deal with the fact that high noon is happening at 11:59 AM. They will look back at us and wonder why we couldn't just write better code.
What This Actually Means
This decision is a massive white flag waved by the software engineering community. We have built a civilization so fragile, so dependent on sub-millisecond synchronization for high-frequency trading and GPS routing, that we cannot tolerate a single hiccup from the cosmos. We would rather let the sun drift across the sky than rewrite our legacy NTP daemons.
It is also a reminder that time is entirely made up. We pretend it is an absolute, immutable law of nature, but it is actually just a shaky compromise between French bureaucrats, atomic particles, and how fast a giant wet rock spins through a vacuum.
For now, you can sleep easy in December 2026. There will be no extra second. You will not get that bonus moment to reflect on your life. Your phone will tick smoothly from 23:59:59 to 00:00:00, and somewhere in Silicon Valley, a systems administrator will quietly weep with relief.
Quick Answers
Why are we canceling the leap second?
Because modern computers lose their minds when a minute has 61 seconds. It causes servers to crash, websites to go down, and airlines to stop functioning.
Will the sun rise at midnight now?
Not anytime soon. The drift is incredibly slow—about one minute every hundred years. You won't need to eat breakfast in the dark for a few millennia.
How did tech companies handle this before?
They used "leap smearing," which involved slowing down their clocks by a tiny fraction of a percent over 24 hours so the extra second was absorbed without the servers noticing.
