If you're of a certain age, you certainly remember the rampant doom forecasted around Y2K—when people were practically predicting an apocalypse in 1999, as we looked ahead to the clock striking midnight on the year 2000. As it turns out, that transition went relatively smoothly. However, a similar, quieter moment is upon us, and it might really do some damage.
Tomorrow, June 30, there will be an extra second added to the day to account for the earth's rotational movement slowing down. According to The Next Web, scientists have added this so-called "leap second" 25 times since 1972 to ensure the atomic clock is in sync with this planet we call home.
The last time this occurred was in 2012, and it did a decent amount of havoc-wreaking. Popular websites like Reddit, Foursquare, Yelp, LinkedIn, and StumbleUpon crashed. Hundreds of flights in Australia were significantly delayed. Systems required full reboots before they were back online.
Tomorrow's leap second is even more at risk as it's taking place on a weekday, while the stock market is open. According to Bloomberg Business, one single second of downtime could cost the market $4.6 million; however, international markets have been preparing.
Is this the first you're hearing of tomorrow's leap second? Read more on Bloomberg, then join us in crossing our fingers that all stays relatively calm!
