How does Windows synchronize?
It's time to talk about how Windows synchronization works. Responsible for this in the Microsoft operating systems service, which is called W32Time.
In order to configure it, you needmake appropriate changes to the registry. The most frequently used parameters relate to the source lists for time, as well as the intervals of this synchronization, after which the source will be accessed.
Windows XP Time Synchronization occursonly from one source. Even if there is a rich list on your list, the system will use only one. Why do they indicate a large number of sources? Everything is very simple. This is done so that if the first is unavailable, the system accesses the next list.
If there are problems with the following,will happen to the third, fourth and so on, until the procedure is completed successfully. The synchronization of Windows 7 is done in the same way.
The specified source list forsynchronization using a special registry key. It looks like this: HKEY_LOCAL_MACHINES SYSTEMS CurrentControlSets Servicing W32Times Parameter NtpServers. The last value is a key that is separated by spaces and is a list of time servers. It can be specified either by a domain name or by the IP address itself. Each of these servers can have the specified hexadecimal values for the flags, which must be specified comma-separated. This is prescribed after each server name.
There are four possible flags. The first one is 0x01. It is called a special interval. The second one is 0x02. It is called "used only as a spare". The third one is 0x04. It is called symmetrically active. And finally, the fourth one is 0x08. It is called a client. Windows time synchronization can only occur with these flags.
When you use the first, you must specifyvalue for the interval in the key that is responsible for the given interval. By default, the system is set to one week. Thus, the synchronization of Windows time occurs every 604,800 seconds. If the accuracy of the system clock is low, this interval is too long.
Some devices have an error ina few minutes from the update to the update. Therefore, it makes sense to shorten the interval in such a way that the Windows time synchronization is performed in a few hours. This change does not significantly increase your traffic or load on the server. However, such an adjustment will enable you to maintain a fairly high accuracy of your computer clock.
When you make the necessary changes to yourregister, confirm them, then you will need to reboot your system. After that, the update interval will be reduced to the one that you set for this purpose.
Now you can be 100% sure,that the clock on your computer or laptop will display the correct time. I just want to warn you that working with the registry is necessary very carefully and carefully. No errors are allowed. Otherwise, you risk reinstalling your operating system.
