Description:
Meta wants to spearhead an industry-wide move away from what it says is a confusing, decades-old tradition.

FULL STORY ======================================================================

Meta has proposed doing away with "leap seconds", offering to support an industry effort to stop any future usage of the confusing and potentially dangerous practice.

A leap second is a measure used to combat the long-term slowdown in the
Earths rotation , caused by the constant melting and refreezing of ice caps, and the imprecise natureof observed solar time (UT1).

First introduced in 1972, global time watchdog the International Earth Rotation and Reference Systems Service occasionally elects to add another second to an hour. Why the move?

"As an industry, we bump into problems whenever a leap second is introduced," Meta production engineer Oleg Obleukhov and Meta research scientist Ahmad Byagowi wrote in a blog post . "And because its such a rare event, it devastates the community every time it happens"

"With a growing demand for clock precision across all industries, the leap second is now causing more damage than good, resulting in disturbances and outages."

Meta also noted that the leap second can be confusing for computers.

Back in 2012, Reddit experienced a massive outage because of a leap second; rendering the highly popular website inaccessible for 30 to 40 minutes.

The time change reportedly confused Reddit's high-resolution timer (hrtimer), sparking hyperactivity on the servers, which locked up the machines CPUs.

It's not just Reddit that has experienced issues due to the practice.

In 2017, Cloudflare posted a very detailed article about the impact of a leap second on their public DNS, claiming the root cause of the bug that affected their DNS service was the belief that time cannot go backward. READ MORE:

To combat these potentially disastrous outages, big tech firms such as Meta and Google have been using a technique called smearing, where the leap second is "smeared" over a longer period of time, or 17 hours in Meta's case.

It's not just Meta that is highly critical of the practice.

TheInternational Telecommunication Unionis debating whether or not to end
leap seconds and will publish a report on the topic in 2023.

There have been 27 leap seconds added since 1972, and there's a good chance that could be all we ever see. Want to make the best of the seconds that you already have? Check out our guide to the best time management apps
