The degree of accuracy of clocks on the Internet is usually defined in "hour levels". The highest, first level, is synchronized with the most accurate clocks, for example, with an atomic time standard, a GPS system or GLONASS (Unified State Time Scale of the Russian Federation). The next in accuracy, the second level, is synchronized with one of the servers of level 1, etc. The synchronization process itself today is carried out using the Internet and local networks, and, of course, any Internet visitor can see the time of a high degree of accuracy on the network.
Instructions
Step 1
To find out the exact time, you just need to go to any of the sites that provide such a service, for example, the site of the Main Metrological Center of the State Time Service - vniiftri.ru. A clock with the inscription "Standard time of Russia" in graphic and digital (including microseconds) versions is located on the right side of the site pages. The site direct-time.ru, in addition to showing the exact time, will compare it with your computer clock if you click the link “Compare the time.” On the website worldtimeengine.com you can find out the exact time in any locality - start entering its name, and the site will try to guess it. Then press the "Get Time" button and get the exact time at this point, and in addition a lot of information from the time zone and the end date of "summer time" to a satellite map of the area.
Step 2
It should be borne in mind that with the default settings, the operating system of your computer itself, without your participation, must synchronize the time of the computer clock with the time of the Internet time servers. If this setting works correctly, then you always have the time that you want to find on the net before your eyes. Double-clicking on the clock on your computer opens the window for setting the properties of the date and time. Enabling synchronization with the time of the Internet server is located on the "Internet Time" tab - there you should check the box next to the inscription "Synchronize with the time server on the Internet". In the "Server" field, you can select from the list or specify your own version of the server that is the source of the exact time, and by clicking the "Update now" button, you can start an unscheduled synchronization. Synchronization of the computer's internal clock with the Internet time is carried out using a simplified version of the specially developed NTP protocol (Network Time Protocol). Its main feature lies in the fact that the protocol makes it possible to make a correction for the constantly changing signal transmission time from the server to the computer. The accuracy of such synchronization can reach one hundredth of a second.
