NTP<\/a> (Network Time Protocol) is an internet based protocol designed to synchronise the clocks on a computer network. It is the main time synchronisation software used in computer networks and is also packaged with most operating systems.<\/p>\n

An NTP server<\/a> is a dedicated device that receives a single time source then distributes it amongst all devices on a network. The protocol NTP monitors the drift of the internal clocks on a network and corrects for them.<\/p>\n

An NTP server<\/a> can receive a time source from either a national physical laboratory such as the UK\u2019s National Physical Laboratory (NPL<\/a>), however, these time signals are broadcast via long wave radio and have finite range.<\/p>\n

GPS NTP servers<\/a> are designed to receive the time source generated by the atomic clocks onboard GPS satellites (Global Positioning System). GPS is available anywhere on the planet as a time source as long as there is a clear view of the sky.<\/p>\n

Without correct synchronisation all sorts of potential problems can occur such as leaving a computer system vulnerable to fraud, malicious users and hackers. An unsynchronised computer network may also lose data and be difficult to audit.<\/p>\n

A global timescale called UTC <\/a>(Coordinated Universal Time) has been developed to ensure the entire world uses the same timescale. The NTP server<\/a> utilise UTC ensuring the computer network is telling the same time as every other computer network.<\/p>\n","protected":false},"excerpt":{"rendered":"
