Timekeeping groups are exploring ending leap seconds to prevent potential timing bugs similar to Y2K concerns.
A retirement could affect how clocks, servers, and software handle time updates in the future.
Official decisions are not final yet and timelines vary by country and organization.
Quick read · 1 min
Time authorities are weighing the retirement of leap seconds to avoid future timing glitches. That could mean a continuous time scale for clocks, servers and software, with updates required behind the scenes.
What it means for you: keep devices and apps up to date and watch for official guidance from standards bodies. In the longer run, critical systems and cloud services may implement changes to keep time stamps reliable without extra seconds.
Leapseconds could be retired entirely
Systems will need testing for a steady time scale
Consumer impact should be minor, mainly software updates
The big idea is simple: some time authorities want to retire leap seconds before they cause trouble later on. Leap seconds are occasional extra seconds added to a day to align atomic time with the Earth’s rotation. As the planet’s rotation isn’t perfectly steady, administrators insert a second here or there. The push to end this practice has momentum, but no universal deadline has been set yet. The path forward appears to favor a continuous time scale without those occasional inserts.
So why should everyday readers care? Time matters everywhere online and in real life. Servers rely on precise time to schedule tasks, update certificates, and keep logs in order. If the world shifts away from leap seconds, systems will need updates and careful testing to avoid new failure modes. For most people, the change won’t show up as a visible clock change, but below the hood it could influence how apps and services handle timestamps and security checks.
01
What are leap seconds and why are they controversial?
Leap seconds are the extra seconds added to a day occasionally to keep atomic time in sync with Earth’s slower rotation. The mismatch between Earth’s spin and atomic clocks grows over time, creating a ticking complexity for some systems. Critics say the edge cases and maintenance burden of leap seconds can introduce risk for critical software and infrastructure more often than not.
02
Where the decisions stand
Timekeeping is coordinated across many labs and standards bodies around the world. A shift away from leap seconds would require broad agreement and a transition plan that minimizes disruption. While some groups favor retiring leap seconds, no fixed timetable exists and discussions continue among international bodies and industry partners.
03
Practical impact for devices and services
In the near term, most people won’t notice a difference in everyday clocks. The real changes would be on the software side: developers and operators would adapt to a world without jump seconds, updating systems that rely on exact timestamps for cryptography, scheduling, and logging. The outcome could reduce rare timing quirks but means preparedness for a new, continuous time scale.
04
What happens next
Expect ongoing talks, pilot programs, and possible transition plans from standards bodies and tech companies. If a path is chosen, it will come with a clear roadmap for developers and operators to test and implement changes without disrupting services.
No immediate action is needed from most users. Stay current with device and app updates, and follow official guidance from timekeeping bodies and major platforms. If you manage critical systems, coordinate with vendors on how they’ll handle a leap-second–free future and what testing is required.

Quick answers
Will my clock stop working?
No, but software and devices may need updates to handle a world without leap seconds.
When will this happen?
No fixed date yet; decisions are still being discussed across international groups.
Should I worry about time stamps in banking or email?
In the near term, not immediately, but some systems may need updates as plans progress.
