On November 18, 2022, the International Bureau of Weights and Measures reportedly announced plans to phase out leap seconds by 2035. That would end more than a century of calendar adjustments meant to keep atomic time aligned with Earth’s uneven rotation.

## Key Details: How Big Tech Prepared For Leap Seconds Removal

Meta warned the industry publicly about serious software risks from leap seconds. It pointed to a **2012** Reddit outage, caused by a leap second insertion, as a clear example of the danger. Google tackled the problem with a proprietary synchronization method called leap smear, which spreads added milliseconds across a full **24-hour** period instead of inserting an extra second all at once.

Amazon Web Services later adopted the same approach across its EC2 infrastructure, protecting cloud instances from timing anomalies. Internet of Things hardware creates a major complication: updating firmware worldwide is nearly impossible. Reports point to an urgent need to modernize how we track planetary movement.

**The 2012 Reddit outage showed how a single extra second could disrupt online services.**

## Context: Understanding The Shift From Astronomical To Atomic Time

Scientists can’t control the physical forces that determine our planet’s rotational speed. When Earth slows, officials add a second so astronomical observations stay aligned with digital clocks. In recent years, they even considered a negative leap second because the planet’s rotation had sped up slightly.

The Bureau International des Poids et Mesures carries responsibility for maintaining the international standard. Based in Sèvres, France, the organization maintains Coordinated Universal Time (UTC), and the last adjustment of any kind came on **December 31, 2016**, beginning a long pause in manual interventions.

| Standard | Maintained By | Location | Status |
| --- | --- | --- | --- |
| UTC | BIPM | Sèvres, France | Active |
| UT1 | Observatories | Global | Variable |
| Leap Smear | Google / AWS | Cloud Infrastructure | Deployed |

## What’s Next: The Roadmap For Leap Seconds Removal

The proposed timeline gives engineers plenty of time to reconfigure critical digital infrastructure. Major providers should be able to move away from traditional atomic clock dependencies without widespread disruption. The aim is to avoid a huge remediation effort like the Y2K bug crisis, with future-proofing focused on separating human schedules from strict astronomical alignment.

Navigation systems can keep tracking precise orbital mechanics while consumer applications rely solely on stable atomic oscillation. This separation should prevent minor planetary fluctuations from threatening global connectivity again, while organizations adapt to new data paradigms. By ending manual calendar corrections, we prioritize computational reliability over strict astronomical alignment, bringing the era of unpredictable clock jumps to a close.

## FAQs

### When will leap seconds be permanently discontinued?

The International Bureau of Weights and Measures reportedly plans to phase out leap seconds by **2035**.

### What software failure proved the dangers of calendar corrections?

A major Reddit outage in 2012 showed how an extra second inserted instantly could bring large-scale web platforms down.

### How does leap smear prevent server crashes?

Rather than adding the extra second in one instant, leap smear gradually inserts milliseconds over a full twenty-four-hour period.

### Why are IoT devices unable to handle new time protocols?

Updating firmware across billions of embedded sensors worldwide is [technically](https://arstechnica.com) impossible, so patches aren’t feasible.

### Does removing leap seconds affect space travel?

Navigation satellites will keep tracking precise orbital mechanics independently of consumer-facing digital clocks. Source: [Theregister](https://www.theregister.com/networks/2026/10/19/time-lords-kill-leap-seconds-before-they-become-the-new-y2k-bug/5303711)
