The year 2015 will have a second longer, reported the International Service Rotation Earth and Reference Service (IERS) on Monday (5). Although adding no more than a glance, how some digital services to receive can cause widespread interference around the internet.
The second longer occur at the turn of the 30th of June to 1 July. When the clock register 23h59m59s, the pointer does not automatically switch to 00 the next day. The increase has occurred in other years. Results from a mismatch between the universal system of time measurement and time records made by atomic clocks.
As time measured by Coordinated Universal Time (UTC, its acronym in English) delays due to a slowdown in the movement of Earth's rotation, atomic clocks not suffer from it. Continue counting the seconds usually. To reach a balance from time to time, the IERS announces additional seconds. Since 1972 there have been 25.
In practice, the clocks have to read a Second Additional, the 23h59m60s, which will give the June 30 a total of 86401/2. It may seem little, but in 2012, last time an addition was made, the internet world has suffered a wave of instability. The problems occurred with Mozilla, Reddit, Foursquare, Yelp, LinkedIn, the Linux operating system and applications running on Java.
The failure may occur because many computer systems, including computers, laptops, smartphones and the like, use the Network Time Protocol (NTP), which records the time and is aligned with atomic clocks. Most, however, are not prepared to deal with an extra second.
The same problem occurred with Google in 2005, when an extra second was added. The company's systems were not prepared. Some of them "refused" to work while had a "wrong" measurement time. The problem was identified in 2008 by engineers, who began working on a way to dribble it.
The solution was to implement an internal change in the NTP. Milliseconds are added to time throughout the day that will have a second longer. So when the time comes, the second has been added naturally. 
The addition of seconds is subject to international discussions. The United States wants to end the extras. They argue that the correction hinders navigation and communication systems, and can disrupt financial transactions that require an accurate record of time. But the UK is defender of extra seconds. The argument is that the exclusion could create a disturbance in the concept of time, and that would mean "dissolve" the system of time zones adopted from the Greenwich Meridian.
