Time synchronisation<\/a> is extremely important for modern computer networks. In some industries time synchronisation is absolutely vital especially when you are dealing with technologies such as air traffic control or marine navigation where hundreds of lives could be put at risk by lack of precise time.<\/p>\n

Even in the financial world, correct time synchronisation is vital as millions can be added or wiped off share prices every second. For this reason the entire world adheres to a global timescale known as coordinated universal time (UTC<\/a>). However, adhering to UTC and keeping UTC precise are two different things.<\/p>\n

Most computer clocks are simple oscillators that will slowly drift either faster or slower. Unfortunately this means that no matter how accurate they are set on Monday they will have drifted by Friday. This drift may be only a fraction of a second but it soon won\u2019t take long for the originally UTC time to be over a second out.<\/p>\n

In many industries this may not mean a matter of life and death of the loss of millions in stocks and shares but lack of time synchronisation can have unforeseen consequences such as leaving a company less protected from fraud. However, receiving and keeping true UTC time is quite straight forward.<\/p>\n

Dedicated network time servers<\/a> are available that uses the protocol NTP<\/a> (Network Time Protocol) to continually check the time of a network against a source of UTC time. These devices are often referred to as an NTP server<\/a>, time server or network time server. The NTP server <\/a>constantly adjusts all devices on a network to ensure that the machines are not drifting from UTC.<\/p>\n

UTC is available from several sources including the GPS network. This is an ideal source of UTC time as it is secure, reliable and available everywhere on the planet. UTC is also available via specialist national radio transmissions which are broadcast from national physics laboratories<\/a> although they are not available everywhere.<\/p>\n","protected":false},"excerpt":{"rendered":"
