The Perils of Online Time Servers

  |   By

For computer networks, accurate time is essential for preventing errors, fraud and ensures security. Everything from internet banking to air traffic control relies on precise and accurate time, but many organisations take unnecessary risks when it comes to the time on their networks and rely on online time servers instead of a dedicated NTP server

Installing a GPS Time Server for Network Synchronisation

  |   By

As the name suggests, GPS time servers receive their time from the GPS system (Global Positioning System). The GPS signal is basically just a time code sent down from the satellites’ onboard atomic clocks. This time signal is what satellite navigation systems use to triangulate positioning, but because it is generated by atomic clocks is extremely accurate and precise.

Understanding your Network Time Server

  |   By

Network time servers are responsible for providing a network’s time. Of course, all computers have their own onboard clocks built into the motherboards, but these devices are only cheap oscillators and are prone to drift. When you have a network of hundreds or even thousands of PCs and devices, if there was no synchronisation to a single network time source, all the machines could be relaying completely different times, often several minutes apart.

Keeping Time with Network Time Protocol

  |   By

When it comes to network time synchronisation, Network Time Protocol (NTP) is by far the most widely used software protocol. Whether it’s for keeping a network of hundreds or thousands of machines synchronised, or keeping a single machine running true, NTP offers the solution. Without NTP, and the NTP server, many of the tasks we perform on the internet, from shopping to online banking, simply wouldn’t be possible.

Using GPS for Accurate and Secure Time for any Network

  |   By

Perhaps the safest and most accurate means of obtaining a time source is by utilising the time codes transmitted by the GPS (Global Positioning System). All that is required for picking up these GPS signals is a GPS NTP server, which will not only receive the time code, but also distribute it around the network, check for drift and maintain stable and precise time on all machines.

Receiving GPS Time for Network Synchronisation

  |   By

To synchronise a computer network or other technology systems to GPS time, all that is required is a GPS network time server. GPS network time servers are simple to install, simple to use and can maintain accuracy for all sorts of technologies. Used by organisations as diverse as stock exchanges, air traffic control and banking systems, GPS time servers provide an efficient and cost effective solution to maintain network synchronicity.

The Cost of Inaccurate Network Time

  |   By

When a network loses time, you are at risk of losing far more than just what time of day it is. Time is an essential aspect of network security and any errors in a network time server can lead to catastrophic result. However, the solution for ensuring network security is fairly simple and relatively inexpensive – the NTP time server.
