Experts have said that adding a leap second this year may result in problems with the computing world as the world community is planning to add a second on 30 June, 2015.

A leap second is required to be added this year in order to make sure the time on atomic clocks stays in sync with Earth's rotational time. However, some of the internet based firms are concerned about the day. The International Earth Rotation Service has recommended a plan to add a second every now and then to keep the standard atomic time in sync with Earth's time

Experts have said that the Earth's rotation has been slowing by about two thousandths of a second every day. However, atomic clocks that are accurate up to quadrillionths of a second do not incorporate this change. They said that the situation is not immediate and will not effect working immediately but it might become out of sync with Earth's rotation and show inaccurate timings in the future.

DemetriosMatsakis, chief scientist for time service at the U. S. Naval Observatory said, "Earth is slowing down over geological time, and that can lead to a problem when you've got a ton of clocks. What do you do when the day gets longer?"
