But how accurate are all these clocks and does it matter if they are all telling different times? For our day-to-day business it probably doesn't matter too much. If the office wall clock is a faster than your wrist-watch your boss probably won't fire you for being a minute late but when it comes to solving criminal cases, timing is everything! Take the case of Joan Beddeson, a 71-year-old found murdered in her home in Macclesfield.
  • Use a NTP Server To Keep Precise Network Time - Computers systems have internal real-time clocks that are notoriously poor at keeping accurate time. Hence, the time on all computers and network devices can drift away from one another at different rates. This can be a real headache when trying to synchronise time-critical processes. However, it is quite simple to synchronise every device on your network to an accurate time reference - a NTP time server. NTP servers are Internet, or locally, based time references that maintain a highly precise time and make this time available to client computers.
  • How to Configure an NTP Network Time Server in Windows XP - Computer time synchronisation is highly important in modern computer networks, precision and time synchronization is critical in many applications, particularly time sensitive transactions.
  • The Significance of an accurate Time Server - This article demonstrates the implication of poor network time synchronisation and how significant it is to have network time in your Companies.

It not only provides the only frame of reference between all devices, it is critical in everything from securing, planning and debugging a network to providing a time stamp for applications such as data acquisition or email. Microsoft Windows XP has a time synchronisation utility built into the operating system called Windows Time (w32time.exe) which can be configured to operate as a network time server. It can be configured to both synchronise a network using the internal clock or an external time source. For many applications, an internal clock can be quite adequate, although, on a network, problems can arise with applications such as sharing network files or in some environments even fraud, so it is vital for security reasons to use an accurate timing source for your network.
  • Use of GPS for Computer Timing Applications - The Global Positioning System (GPS) is now a very familiar tool in helping motorists to navigate but GPS has more uses than merely triangulating a position for direction finding, it can also be utilized to provide time and frequency information worldwide. Developed by the United States military, GPS incorporates at least 24 communication satellites in high orbit, all of which contain precise timing equipment to enable the satellite to triangulate positions accurately. However, each satellite's highly accurate atomic clock timing reference can also be used by NTP (Network Time Protocol) servers to synchronise computer networks using the highly accurate GPS time as an external reference.
  • Time Server's and the Importance of Synchronisation. - Time servers are like other computer servers in the sense they are usually located on a network. A time server gathers timing information, usually from an external hardware source and then synchronises the network to that time.
  • Synchronised Time on your Computer - An accurate time reference is very important for the use of computer software applications. Athough every Computer includes an internal clock, it pays to check time and date settings are correct on your PC every time you turn it on. For important applications, the time base should be synchronised with a highly accurate external time source. Personal Computers are not designed to be perfect clocks. Their design has been optimised for mass production and low-cost rather than maintaining accurate time. Where time is crucial to the application, there are a number of precise external references available that enable computers to maintain accurate system time.

  • The Lost Eleven Days - Have you ever gone to bed one night and wondered just where the day went? Well could you imagine waking up to discover that eleven days had vanished completely? That is just what happened in 1752 when the entire inhabitants of Britain and America went to bed on Wednesday 2 September, only to awake on Thursday 14 September. However, it wasn't an epidemic of sleepy sickness or even a mass dose of laziness that kept the entire populace in bed but merely the authorities attempting to synchronise with the rest of the world by adopting the Gregorian calendar.
  • NTP Security: Authentication and Trusted Time References - NTP (Network Time Protocol) synchronises networks to a single time source using timestamps to represent the current time of the day, this is essential for time sensitive transactions and many system applications such as email. NTP is therefore vulnerable to security threats, whether from a malicious hacker who wants to alter the timestamp to commit fraud or a DDoS attack (Distributed Denial of Service - normally caused by malicious malware that floods a server with traffic) that blocks server access.
  • NTP Server Reference Clocks: What's Best Radio or GPS ? - A NTP Server is a network device that provides network servers and other network infrastructure with an accurate timing reference. A NTP Server obtains precise time from an external time source, such as radio time and frequency broadcasts or GPS. This article describes the external time references that are available to synchronise NTP servers and discusses the merits of each. There are a number of radio time and frequency broadcasts that are available in various locations. The WWVB signal is a US based reference, DCF-77 in Germany and MSF in the UK. These radio time and frequency broadcasts provide a stable and precise source of time.
  • What is Time? From Sundials to NTP - Time is an abstract concept. We cannot necessarily see it, touch it or change it, but we are aware that it exists and that is continues to keep passing us by. It has long been thought that time was constant and was the same everywhere in the Universe. However, Albert Einstein's theories of relativity (General and Special Relativity) have changed the way we think about time. Einstein suggested that time is part of a four dimensional 'space-time' the other three dimension being the up/down, left/right, forward/backward dimensions we are all aware of.
  • History of Horology; Sundials to Atomic Clocks - Mankind has always been preoccupied with measuring and recording the passage of time. Timekeeping has been essential for the development of civilisations;
  • Amaze Yourself - Download your Audio Books From your Hard drive to your ipod - If you have iTunes software installed on your computer, upon inserting the CD with your audio files on it, into your computer, all audio files will automatically upload onto your hard drive. However, due to certain restrictions, known as DRM (digital restrictions management), should you download any audio book directly from a site on the Internet, there is a slightly different process involved. Passwords are required in order to first use digital audio files under DRM, after which they will have to be opened and a short process to ascertain legality completed for you to copy them.
  • What Are the Benefits of Remote Access and Remote Desktop IT Systems? - Remote access is fast being a necessity for many businesses and organisations both large and small.
  • Calendars and the Measurement of Time - We are all aware of the passing of time; it governs us throughout our lives constantly ebbing away, dictating when we should eat, sleep, wake or work. Yet, the concept of time has baffled philosophers and scientists for millennia and we are still unsure of exactly what time is; although the work of Einstein and others has led us some way in its understanding.
  • Hang on a Second: History of the Leap Second - We have all heard of a leap year - that extra day added to the calendar every four years. It may give us a longer February but it is also essential in keeping our calendars and seasons accurate.
