The Network Time Protocol (NTP) is widely used around the World to synchronise computers and to provide an accurate time reference. NTP supports accuracy down to nanoseconds but the real accuracy achieved depends upon the operating system and the Network performance. It relies upon a reference clock to define the time, and synchronises all clocks on the Network to that reference. NTP uses Coordinated Universal Time (UTC) to indicate the current time. UTC is independent of time zones and enables NTP to be used anywhere in the World regardless of the time zone settings. An NTP time server is used to obtain the correct time from an NTP time source and adjust the local time in each participating computer. The time source used by the time server is very important as it forms the basis of time updates across the whole Network. Recent studies show that the use of Internet time servers is not recommended for Industrial or Commercial applications due to high numbers of bad clocks, unbalanced network loads and security considerations. It is now considered essential to use an accurate time source such as GPS or an atomic clock. We offer a range of timing and synchronisation technologies based on GPS which offer an ideal professional level solution.
