Where is the NTP server usually set to? Can it be set to an Internet clock address?

In the cloud computing management platform, the system time between the CVM and CVK hosts must be kept consistent. In general, it is recommended to set up the CVM as the server side of NTP, that is, in setting up the NTP server, just write the IP address of the primary server as the IP address of the CVM, or write the virtual IP of the hot standby if it is a dual-computer hot standby environment. It can also be set to the Internet clock address, but you must ensure that the system time of CVM and CVK are consistent.
