What is the fact behind the process of synchronizing universal time

We live and work in a world totally different from what many of us were born. We are now more likely to buy something over the Internet than walk down to the street market. Also big business and trade has changed with the market becoming truly global and the Internet is the most common tool for trade.

Trading does not provide its overall problems but that different time limits governing the various countries around the globe. To ensure parity within overall was introduced in the 1970s knows Coordinated Universal Time (UTC).

The biggest problem is that most of the clocks and watches, including those built in computer motherboards, are susceptible to drift. And as different machines will drift at different rates, global communication and e-commerce could be impossible. Just think of the difference a second can make in markets such as stocks, exchange where fortunes are won or lost, or when you buy seat reservations online, what would happen if someone computer with a slower clock booked the same seat, you think the computer will display timestamps the person you booked before.

Other errors may result in unexpected, even in internal networks, when the computers are running at different times. Data can be lost, mistakes can be difficult to log, track and correct and malicious users can take advantage of the confusion of the time.

To ensure truly global synchronization, computer networks can be synchronized with an atomic clock that allows all computers on a network to remain within milliseconds of UTC. Calculate the use of networks of servers NTP (Network Time Protocol) to ensure precise timing, most of the time NTP servers receive the atomic clock of the GPS satellites or other radio frequency.
