While atomic clocks relay an accurate, unchanging form of chronology, the Earth\u2019s rotation varies slightly from day-to-day, and in essence is slowing down by a second or two a year.<\/p>\n<p>To prevent noon, when the sun is highest in the sky, from slowly getting later and later, Leap Seconds are added to UTC as a chronological fudge, ensuring that UTC matches GMT (governed by when the sun is directly above by the Greenwich Meridian Line, making it 12 noon).<\/p>\n<p>The use of leap seconds is a subject of continuous debate. The ITU argue that with the development of satellite navigation systems, the internet, mobile phones and computer networks all reliant on a single, accurate form of time, a system of timekeeping needs to be precise as possible, and that leap seconds causes problems for modern technologies.<\/p>\n<p>This against changing the Leap Second and in effect retaining GMT, suggest that without it, day would slowly creep into night, albeit in many thousands of years; however, the ITU suggest that large-scale changes could be made, perhaps every century or so.<\/p>\n<p>If leap seconds are abandoned, it will effectively end Greenwich Meantime\u2019s guardianship of the world\u2019s time that has lasted over a century. Its function of signalling noon when the sun is above the meridian line started 127 years ago, when railways and telegraphs made a requirement for a standardised timescale.<\/p>\n<p>If leap seconds are abolished, few of us will notice much difference, but it may make life easier for computer networks that synchronised by <a href=\"https:\/\/www.ntp-time-server.com\/\">NTP time servers<\/a> as Leap Second delivery can cause minor errors in very complicated systems. Google, for instance, recently revealed it had written a program to specifically deal with leap seconds in its data centres, effectively smearing the leap second throughout a day.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>International Telecommunications Union (ITU), based in Geneva, is voting in January to finally get rid of the leap second, effectively scrapping Greenwich Meantime.
