Is the Leap Second 2015 a danger like Y2K Many IT companies are dreading over the leap second 2015. Most of these companies are considering the leap second as another Y2K-like bug. However, a recent blog on MSDN clears the air saying that leap second 2015 that is coming on June 30th is not a severe problem like Y2K and it will be taken care by most of the IT companies like Microsoft and Google. The concept behind a leap second and a leap year is same. It is basically a one-second adjustment done to the UTC or the Universal Time to match the days’ time adjacent to the mean solar time. Sometimes, due to climatic changes or natural events like earthquake, earth’s rotation varies. This directly affects the mean solar time. In order to match this irregular time, the leap seconds of UTC are made irregular and hence they become, slightly unpredictable. In simple words, when the event like leap second occurs, the UTC system’s clock can tick a second at any time, to adjust that extra second. The event of leap second hasn’t appeared for the first time. The last time it appeared was the year 2012. And this year it is going to occur on June 30th. The extra second will be inserted in the UTC at 23:59:60. IERS or the International Earth Rotation Service measures the earth’s rotation and makes sure if it is in sync with UTC. If it is delayed than UTC, then IERS decides when to insert a leap second to UTC. Generally, the leap second is inserted at the end of June or December and at UTC midnight. This time also, it is going to take place at the end of June. Basically, it is not the Leap second 2015; but it is the effect that this leap second might have on the computers and software that people are worried about. IT companies are even calling this extra second as the leap second bug. As per their prediction, the software cycle will go haywire due to this extra second and the program may respond in an unpredictable way; as it might misinterpret the leap second. So basically, when the clock completes the 3rd step, it should go to 5th step mentioned in above list. However, an extra second is inserted and that makes as 1 extra leap second. And people are worried that the software programs, internet and computer’s system clock will the 4th and 5th step as same and will overlap the procedures.
