News

TimeTools new US website is now live. This will provide customers in the North American region greater access to our NTP Server products.

TimeTools new SR and SC series of rack-mountable and compact time servers are now being shipped. Offering a complete range of Linux based true stratum 1 time references that provide a real breakthrough in price and performance.

The units can be provided with a range of reference clock options for true flexibility. High stability TCXO oscillator options can also be provided to increase holdover in the event of the loss of the primary reference clock.

Our confidence in the reliability of the new devices is reflected in the provision of an industry leading 5 year warranty.

UPDATE !!! The SR/SC series is now provided with a cutting-edge high-sensitivity GPS receiver that can often operate with an indoor located GPS antenna. Additionally, the new receivers can operate from a single satellite-in-view making operation from a window often possible. These features potentially provide a great saving on installation costs when compared to traditional roof-mounted GPS antennas. Of course, our GPS antennas are completely weather-proof and can still be roof-mounted, if required.

A new SR9860D will be available soon with increased processing power and accuracy. Able to synchronise to within 1usec UTC and serve in excess of 128,000 clients.

NTP Authentication
NTP authentication is intended to overcome any security risks associated with the Network Time Protocol. Authentication allows a NTP client to ascertain that a response to a request for time has actually come from the expected NTP server. A client can authenticate a server to ensure that no one has maliciously intercepted the communication between the client and server. .... more>>

NTP on LINUX
NTP is an acronym for Network Time Protocol. It provides a standard means of disseminating time to servers, workstations and general network infrastructure. It is a client-server based protocol that utilises UDP over TCP/IP and is widely used across the Internet. Originally developed for the Linux operating system, it has since been ported to Microsoft Windows. The protocol and associated applications and tools are freely distributable under a public licence from the NTP web site, no charge or subscription fee is demanded for its use. This article describes how to install and configure a Linux based time refernce....more>>

Reference Clocks
A number of external hardware reference clocks are available to synchronise NTP time servers. One of the most common is the Global Positioning System (GPS). GPS provides a highly accurate source of time, typically to a few hundred nanoseconds. GPS has the advantage that a good signal can be obtained anywhere in the world. All that is required is a GPS receiver and antenna...more>>

Why Use GPS For Accurate Timing Systems?
GPS is increasingly being used as a standard hardware clock reference for NTP servers and other computer timing systems. GPS is a US military system that consists of an array of 24 satellites arranged in a constellation that covers the entire globe. Each satellite contains a high precision atomic clock to provide accurate time and positioning information to Earth based systems.
