An extra second will be added to the Earth's official clock today, but some computer programs might have trouble handing it, according to a report by ABC News.
The "leap second" is needed to account for a discrepancy between Earth's rotation and the atomic clock, according to the International Earth Rotation and Reference Systems.
In the United States, the extra second will be added at 8 p.m. Eastern time. It's possible that programs not designed to handle the extra second could have issues, the ABC story said.
Websites such as Qantas, LinkedIn and Yelp had problems the last time a leap second was added on June 30, 2012, according to the story.
Amazon Web Services said last month it plans to "implement alternative solutions" to avoid the leap second, ABC reported. "AWS clocks will be slightly different from the standard civil time for a short period of time."
