No matter where we are in the world we all need to know the time at some point in the day but while each day lasts for the same amount of time no matter where you are on Earth the same timescale is not used globally.<\/p>\n

The impracticality of Australians having to wake up at 17.00 or those in the US having to start work at 14.00 would rule out suing a single timescale, although the idea was discussed when the Greenwich was named the official prime meridian (where the dateline officially is) for the world some 125 years ago.<\/p>\n

While the idea of a global timescale was rejected for the above reasons, it was later decided that 24 longitudinal lines would split the world up into different timezones. These would emanate from GMT around with those on the opposite side of the planet being +12 hours.<\/p>\n

However, by the 1970\u2019s a growth in global communications meant that a universal timescale was finally adopted and is still in much use today despite many people having never heard of it.<\/p>\n

UTC, Coordinated Universal Time, is based on GMT (Greenwich Meantime) but is kept by a constellation of atomic clocks. It also accounts for variations in earth\u2019s rotation with additional seconds known as ‘leap seconds’ added once of twice a year to counteract the slowing of the Earth\u2019s spin caused by gravitational and tidal forces.<\/p>\n

While most people have never heard of UTC or use it directly its influence on our lives in undeniable with computer networks all synchronised to UTC via NTP time servers<\/a> (Network Time Protocol).<\/p>\n

Without this synchronisation to a single timescale many of the technologies and applications we take for granted today would be impossible. Everything from global trading on stocks and shares to internet shopping, email and social networking are only made possible thanks to UTC and the NTP time server<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
