Greenwich Meantime


What is NTP? Network Time Protocol is a protocol-based software on the Internet that uses an algorithm to check a computer system clocks and set them adrift with reference to a single source of time. NTP is not the only available time synchronization protocol, but is without a doubt the most popular, since has been constantly updated since its development at the end of the 80s. What is UTC? Coordinated Universal time is the world global calendar, based at Greenwich Meantime (though fits the natural slowdown of the Earth by the increase of leap seconds). UTC is governed by a constellation of watches atomicos from around the world and is used by computer networks, air traffic controls and the commercial world. What is network time synchronization? Network time synchronization is when all the computers in a network are running at the same time. Timing is essential for modern computer networks as a lack of synchronization can lead to the loss of data, system errors, failure of sensitive transactions at the time and you can even leave a network vulnerable to security threats.

Where can I receive UTC? The most common place to receive a source of UTC time is, of course, through the Internet, although users should be warned that they do not offer any guarantee of accuracy, reliability and may leave a system vulnerable to security threats since the UTC source is beyond the firewall. A safer and much more accurate method of receiving the UTC is to use either the network of GPS (Global Positioning System) or radio transmissions specialists from national broadcast provided by several laboratories of physics. What is the difference between a network time server and a NTP server? Nothing, they are really interchangeable names, most network time servers use NTP and, therefore, are NTP servers. Other names for these devices are often cited as they are: time server, Atomic, server clock time or server schedule.
