Clocks successfully re-align with earth's rotation
Was it as good for you as it was for us? The longest day of the year is flying by here at the Guardian’s Sydney HQ. Here’s how the leap second went down, in real time:
You can really feel the excitement, especially because we’ve slowed the video and replayed the reaction of our editor-in-chief, Emily Wilson, whose passion for this extraordinary moment has been the driving source for our live coverage.
Enjoy the rest of your morning, afternoon, or night, fellow time-travellers. The world’s clocks are as accurate as they’re going to be for three years. Make the most of it.

The chaos we all feared is upon us:
Twitter is having problem estimating how long ago tweets were sent. Seeing tweets from a minute ago say they were sent a day ago #leapsecond

Here’s Guardian Australia news editor Mike Ticher (his hands leathered by years of furious typing in air-conditioned offices) trying to capture history.
Good screenshot technique Mike.

As we bask in the vaguely post-coital (or is that just me?) aftermath of the longest minute since 2012, let’s savour this picture of how the leap second went down in the Guardian’s Sydney office.
(As the TV in the corner drones about something or other.)

You can tell your grandkids about this some day. (Unless you already have them, in which case - go tell them now!)

I hope you all enjoyed the #LeapSecond! Personally, I had a low-key celebration at work with the administrative secretary. 🎉
Bet neither of you will ever forget it.

The leap second appears to have unravelled Karen’s pink scarf - this is what happens when you mess with nature, people.

Poor David thinks the danger has passed.
That #leapsecond was a total anticlimax.

The aftermath
Think: that scene in 28 Days Later when your man walks out of hospital to find London abandoned.
We’re tracking the consequences of the leap second here in our usual sober, measured way. Time.gov took a little longer to load then usual. Any other consequences to report?

Consternation has erupted in Leap Second Excitement HQ (aka the Guardian office in Sydney) as we realise our clocks differ. We *think* it’s 9:59 aka the longest minute of our lives (since 2012).Consternation has erupted in Leap Second Excitement HQ (aka the Guardian office in Sydney) as we realise our clocks differ.

Listen: the world has come unstuck in time. This is a lot to think about early in the morning – or late, depending where you are – but bear with me. The leap second is looming. What is it? Let Peter Whibberley explain:Listen: the world has come unstuck in time. This is a lot to think about early in the morning – or late, depending where you are – but bear with me. The leap second is looming. What is it? Let Peter Whibberley explain:
“Over centuries, the Earth has been slowing down,” he says. Surely in 2015 someone can invent a clock that keeps time accurately? Alas, that seems to be the problem.“Over centuries, the Earth has been slowing down,” he says. Surely in 2015 someone can invent a clock that keeps time accurately? Alas, that seems to be the problem.
“Atomic clocks keep much better time than the Earth itself,” Whibberley says. “They are more than a million times more stable.” Coordinated Universal Time, which the world abides by, comprises the average time of 400 caesium atomic clocks globally, all ticking away at the highest level of accuracy.“Atomic clocks keep much better time than the Earth itself,” Whibberley says. “They are more than a million times more stable.” Coordinated Universal Time, which the world abides by, comprises the average time of 400 caesium atomic clocks globally, all ticking away at the highest level of accuracy.
“Previously the Earth was the ultimate reference and man-made clocks were adjusted to match,” says Whibberley. “From the beginning of the 1960s, atomic clocks became the ultimate reference. They were adjusted to keep in step with the Earth. Then, in 1972, it was decided that, instead of adjusting how fast the clocks ticked, they would be left to tick away at the atomic rate and the leap second would be introduced.”“Previously the Earth was the ultimate reference and man-made clocks were adjusted to match,” says Whibberley. “From the beginning of the 1960s, atomic clocks became the ultimate reference.

What’s the big deal? Well, the last time we meddled with time in this fashion it took out the web browser Mozilla. Reddit also crashed – briefly forcing hordes of young men into real-life social interaction – and Qantas bookings were disrupted more than two hours. (LinkedIn also went down, so it wasn’t all bad.)What’s the big deal? Well, the last time we meddled with time in this fashion it took out the web browser Mozilla.
