Why will add a second one for hours in 2015, and why the Internet can crumble in the world?

The second is probably a short period normally do not care, but it is clear they are important when it comes to Balabnak and technology companies and all services that rely on the Internet, which could have caused her second delay problems and stopped working. June 30 of this year, some of the big companies will be in front of a real challenge, according to the International Observatory Aanlh to Paris as a result of delayed international time for one second. What reason? And why? What are the seriousness of the matter on the Internet?


the can crumble in the world

As I said in the introduction French Observatory specialist announced studying the planet need to provide the time the second one in the next summer season this year, since the day June 30, 2015 must watch indicates 11:59:60 instead of 11:59:59, and this in order to achieve a balance between the speed of rotation of the Earth around the same 24 hours between the time.

It was found that our planet is suffering from a slowdown in the speed of rotation about the same amount of two milliseconds every day .asaat worked on a scheduled basis, does not strictly follow these differences. To this must be adjusted to suit the speed of rotation of the Earth around itself.


But, why the worldwide technology companies are worried about the increase again in just one day of the year?
Of course, as we know the services provided by companies rely on time mainly in the work updates and Execution financial transactions etc ... These services operate on the Network Time Protocol account (NTP), a protocol that distributes UTC by synchronizing hours of computers linked together network mechanism one all over the world.

For example, financial transactions specifically can be lost if you did not add a second for Onzma.ohma shows clearly how the world is very interdependent and fragile, and how our systems can be affected for just a second.


In 2012, it is worth mentioning that companies such as Mozilla, and Foursquare, Reddit, Yelp, LinkedIn and StumbleUpon, and Linux systems, as well as some programs that rely on Java, suffered from this problem, in that time. It is expected to be repeated this Alsinareoffa this year if they are not programming computers to deal with the changing times.

It is noteworthy that it is not the first time that this happens. Between 1972 and 1979 have been added the second one at least every Aam.olkn since 1999, has been a calibrated atomic clocks four times.
