The last time this happened 3 years ago. In other words, the total length of the current days will be about 86 thousand. 401 seconds.
But there are fears that the leap second can make some problems for computer networks, since it has to be added manually.
What is it? Her and I added on 30 June. Extend one day in the year required deceleration of the Earth caused by the sun and the moon. However, the first of this century quite frightened others: unexpected start missiles, nuclear breakdown, failures in factories and the like. It depends on the atmosphere of the inner core of the Earth’s tectonic plates and, changes in the ocean, soil and groundwater.
The time is measured in astronomical and atomic clock.
This year, July will come a little later – for one second, if to be exact. This date is one second longer than the conventional hours. Hardware vendors such as Cisco, is now holding consultations on how to respond to their equipment, “leap seconds”, but the side effects is still unpredictable. Scientists have calculated that in fact the Earth revolves around its own axis of 86400.002 seconds.
And if for the introduction of more people a second pass unnoticed, the hardware and software can “go crazy.” Therefore, the council of the song “do not think about the seconds down” in this context takes on a special meaning. The first time it was introduced in 1972. They begin to hang out and lose orientation.
Every six thousand. Years of the passage of the axis of the Earth is different from humanity computable time for one hour, which results in the addition of a second more.
