Global time synchronisation<\/a> may seem like a modern need, we do after all live in a global economy. With the internet, global financial markets and computer networks separated by oceans and continents\u2014keeping everybody running in synchronisation is a crucial aspect of the \u00a0modern world.<\/p>\n

Yet, a need for global synchronicity began a lot earlier than the computer age. International standardisation of weights and measures began after the French revolution when the decimal system was introduced and a platinum rod and weight representing the metre and the kilogram were installed in the Archives de la R\u00e9publique in Paris.<\/p>\n

Paris eventually became the central head of the International System of Units, which was fine for weights and measures, as representatives from different countries could visit the vaults to calibrate their own base measurements; however, when it came to standardising time, with the increased use of transatlantic travel following the steamer, and then the aeroplane, things became tricky.<\/p>\n

Back then, the only clocks were mechanical and pendulum driven. Not only would the base clock that was situated in Paris drift on a daily basis, but any traveller from the other side of the world wanting to synchronise to it, would have to visit Paris, check the time on the vault\u2019s clock, and then carry their own clock back across the Atlantic\u2014inevitable arriving with a clock that had drifted perhaps several minutes by the time the clock arrived back.<\/p>\n

With the invention of the electronic clock, the aeroplane and transatlantic telephones, things became easier; however, even electronic clocks can drift several seconds in a day so the situation wasn\u2019t perfect.<\/p>\n

These days, thanks to the invention of the atomic clock, the SI standard of time (UTC: Coordinated Universal Time) has so little drift even a 100,000 years wouldn\u2019t see the clock lose a second. And synchronising to UTC couldn\u2019t be simpler no matter where you are in the world\u2014thanks to NTP (Network Time Protocol) and NTP servers<\/a>.<\/p>\n

Now using GPS signals or transmissions put out by organisations like NIST (National Institute for Standards and Time-WVBB broadcast) and NPL (National Physical Laboratory\u2014MSF broadcast) and using NTP servers, ensuring you are synchronised to UTC is simple.<\/p>\n

NTP servers like Galleon\u2019s NTS 6001<\/a> GPS receive a atomic clock time signal and distributes it around a network keeping every device to within a few milliseconds of UTC.<\/p>\n
