You probably don't feel it as you rush through your daily digital life, but the Earth's rotation is slowing down. Yeah, right, eh? Seems like there's not enough hours in the day, so that extra second being added tomorrow will really come in handy.
It's called a "leap second" and gets added roughly every 18 months, according to this interesting blog post by The Next Web.
Humans can handle it, but it's more of a problem for computers and apparently "wreaked havoc online" when it was last added back in 2012.
This all brings back memories of New Year's Eve 1999 when there was speculation about e-doom and gloom because of the change to 2000. If I recall, we survived that OK.
It's more technical in nature as the article explains ...
"The leap second is mostly a headache for system administrators who need to ensure their services are highly available and need to plan how to handle the change. Hardware providers such as Cisco now provide detailed advice on how their hardware handles the leap second, but the side effects are unpredictable."
If you want to count it down to a random one-second video with your friends and family, here's a handy Leap Second Countdown Clock from John Oliver.
