In a clustered environment and multi-server applications that require log synchronization, in order to ensure normal collaboration between multiple servers, it is necessary to keep their time consistent, and manually adjust the time on multiple servers is extremely unscientific, and this requires the use of NTP time se

Article Title: system time synchronization and ntp service provision. Linux is a technology channel of the IT lab in China. Some basic classification computers, such as desktop applications, Linux system management, kernel research, embedded systems, and open-source systems, will experience errors soon if they are left blank.

document configuring Windows Time service to using an internal hardware clock, I configured the Windows 2012 physical machine to be an NTP server that uses an internal hardware clock. Note that Microsoft's article how to configure authoritative time servers in Windows serve

This article describes in detail how to configure the NTP time synchronization server, and takes CISCO 7200 as an example. I hope this article will help you. For the purpose of network management, we set up netflow to monitor traffic and obtain detailed access records for Intranet users to access the Internet. Such records can be accurate to seconds, the premise is that the

the Internet to synchronize the time of the computer is very convenient, this way in the LAN has been widely used. Microsoft has embedded the Network Time Protocol (NTP) in a Windows XP system that allows computer time calibration in a LAN or wide area network as long as the computer is networked. The standard

In the computer world, time is very important, for example, the rocket launch of this scientific activity, the unity and accuracy of time requirements is very high, is the time of the computer according to a, or the time of this computer B? NTP is used to solve this problem,
