Network Time Server

The Network Time Protocol (NTP) is used by network time server systems to distribute accurate time received from an external time source, such as MSF, DCF-77 radio and GPS references, to network time clients over an IP ethernet network. Thousands of clients can accurately synchronise their system time using NTP. For many applications and computer based systems precise time is a critical factor in recording accurate information.

There are a number of accurate external time sources available to timing equipment:

1. The MSF radio time signal is broadcast from Anthorne, Cumbria in the UK. It is a long-wave frequency modulated signal , transmitted at 60KHz. The transmitted signal covers the British Isles and much of North-Western Europe. The UK National Physics Laboratory quotes the accuracy of the time signal as being within 1 millisecond of UK local time (GMT\BST).

2. The DCF-77 radio time signal is transmitted from Meinflingen, Frankfurt, Central Germany. It is a long-wave frequency modulated signal , transmitted at 77.5 KHz. The transmission has a range of 2000 Km, covering most of Central and North-Western Europe. Deutsche Telecom claims the broadcast is accurate to with 20 milliseconds of Central European Time. (CET).

3.The WWVB radio time signal is transmitted from Fort Collins, Colorado in the USA. The signal is a long-wave frequency modulated broadcast , transmitted at 60KHz. The broadcast can be received throughout much of the US and parts of Canada. Accuracy of the time signal is quoted at <2 milliseconds.

4. The Global Positioning System (GPS) is widely known as a global navigation and positioning system, particularly car navigation. However, it also has a very precise timing element. Indeed, GPS is easily the most accurate broadcast time reference available, which boasts accuracies in the range of a few nanoseconds. This is enhanced further by the fact that reception is world-wide and soon to be expanded still further by the European Galileo system.

TimeTools has a comprehensive range of computer and network time synchronisation solutions utilising GPS and radio technologies. Solutions range from RS232 serial and USB devices that synchronise time on a single PC to dedicated network time servers that can provide accurate time to thousands of network time clients. We also provide a comprehensive range of ethernet network, NTP synchronised, digital and analog wall clocks that continuously display accurate synchronised time.

• High Precision GPS and LF radio (MSF and DCF-77) time references.
• RS232 and USB time synchronisation devices for accurate PC time.
• Dedicated network time servers to accurately synchronise thousands of clients using the Network Time Protocol (NTP).
• Precise timing for all operating systems including Microsoft Windows, Linux and Unix.
• Synchronise network infrastructure such as Cisco routers, hubs, switches, CCTV cameras, DVR's and telephone systems.
