Accuracy is becoming more and more relevant as technology becomes increasingly important to the functioning of our everyday lives. And as our economies become more reliant on the global marketplace, accuracy and synchronisation of time<\/a> is very important.<\/p>\n

Computers seem to control much our daily lives and time is essential for the modern computer network infrastructure. Timestamps ensure actions are carried out by computers and are the only point of reference IT systems have for error checking, debugging and logging. A problem with the time on a computer network and it could lead to data getting lost, transactions failing and security issues.<\/p>\n

Synchronisation on a network and synchronisation with another network that you communicate with are essential to prevent the above mentioned errors. But when it comes to communicating with networks across the globe things can be even trickier as the time on the other-side of the world is obviously different as you pass each time-zone.<\/p>\n

To counter this, a global timescale based on atomic clock time was devised. UTC <\/a>\u2013 Coordinated Universal Time \u2013 does away with time-zones enabling all networks across the globe to use the same time source \u2013 ensuring that computers, no matter where they are in the world, are synchronised together.<\/p>\n

To synchronise a computer network, UTC is distributed using the time synchronisation software NTP (Network Time Protocol<\/a>). The only complication is receiving a source of UTC time as it is generated by atomic clocks which are multi-million dollar systems that are not available for mass use.<\/p>\n

Fortunately, signals from atomic clocks can be received using a NTP time server<\/a>. These devices can receive radio transmissions that are broadcast from physic laboratories which can be used as a source of time to synchronise an entire network of computers to.<\/p>\n

Other NTP time servers use the signals beamed from GPS satellites as a source of time. The positioning information in these signals is actually a time signal generated by atomic clocks onboard the satellites (which is then triangulated by the GPS receivers).<\/p>\n

Whether it\u2019s a radio referenced NTP server or a GPS time server<\/a> \u2013 an entire network of hundreds, and even thousands of machines can be synchronised together.<\/p>\n","protected":false},"excerpt":{"rendered":"
