Chrony is the two program used to maintain the accuracy of computer system clocks, both of which are named Chronyd and Chronyc.Chronyd is a daemon that runs in the background of the system. He adjusts the system clock by measuring the offset of the local time based on other time server time on the network. For orphaned

CentOS/Linux automatic server synchronization time The newly installed CentOS system server may have an incorrect time, which is very important during cluster creation. It is very likely that the cluster will fail due to time, therefore, you need to adjust the

It is not known why the server is on the wrong system time, nearly 63 minutes faster than the actual UTC. It is easy to confuse when a timestamp checksum is involved in a local file and a remote server file. Here, the process of correcting the system time is recorded as follows.
