A solar-powered airplane finished crossing the United States on Saturday, landing in New York City after flying over the Statue of Liberty during its historic bid to circle the globe, the project team said. The spindly, single-seat experimental aircraft, dubbed Solar Impulse 2, arrived at New York's John F. Kennedy International Airport at about 4 a.m. local time after it took off about five hours beforehand at Lehigh Valley International Airport in Pennsylvania, the team reported on the airplane's website. Such a pleasure to land in New York! For the 14th time we celebrate sustainability," said the project's co-founder Andre Borschberg on Twitter after flying over the city and the Statue of Liberty during the 14th leg of the trip around the globe. The Swiss team flying the aircraft in a campaign to build support for clean energy technologies hopes eventually to complete its circumnavigation in Abu Dhabi, where the journey began in March 2015.

The "leap second" means the spur of the moment of June will have 61 seconds in it. Leap seconds - and leap years - are added as essential approaches to keep the check in a state of harmony with the Earth and its seasons. Be that as it may, there are concerns the additional second could bring about issues for some PC frameworks in light of the fact that it must be included physically. Timekeepers are separated about whether to keep the extra unit of time - and the issue is situated to be discussed at a meeting not long from now.
Flighty revolution
Theexpansion will imply that the spur of the moment of June will have 61 seconds; while 23:59:59 generally turns into 00:00:00, the leap second will guarantee the time turns into 23:59:60.
Dwindle Whibberley, senior examination researcher at the UK's National Physical Laboratory (NPL), said: "In light of the fact that they rely on upon estimations of the Earth's pivot, which differs capriciously, leap seconds happen at sporadic interims." News scope has concentrated on the potential for programming issues that could influence money related exchanging and different operations around the globe. Mr Whibberley, who lives up to expectations in the time and recurrence bunch at NPL, focused on the requirement for arranging. "Leap seconds are declared just six months ahead of time. This implies PCs and programming can't be supplied with leap seconds customized in, and they must be embedded physically," he clarified. "Getting leap seconds wrong can bring about loss of synchronization in correspondence systems, monetary frameworks and numerous different applications which depend on exact timing. "At whatever point a leap second happens, some PC frameworks experience issues because of glitches in the code kept in touch with handle them. The outcomes are especially serious in the Asia-Pacific district, where leap seconds happen amid typical working hours." Since the inconsistency of including leap seconds causes issues for PC systems, a few proposition have been set forward to annul them. The issue is as yet being considered by the International Telecommunications Union (ITU) and is situated to be examined at the World Radio communication Conference in Geneva in November this year. Agents will plan to achieve a choice to either end leap seconds or embrace a specialized answer for diminish the issues they cause.
