See below for managing time synchronization.

In multi-node installations, all the nodes must have synchronized dates to prevent communication errors.

Listing the NTP servers

Run the following command to list the NTP servers currently used by the built-in chrony service.

chronyc sources

When Installing CSP, the installation process automatically configures this service to use the NTP server provided by DHCP. If DHCP does not provide one, chrony uses the following NTP server by default.

pool.ntp.org

Configuring chrony

To modify the default chrony configuration, edit the following file on all the installation nodes. 

/etc/chrony.conf

Do not modify the following lines in any case.

bindcmdaddress 0.0.0.0
cmdallow all

See a reference of the chrony parameters at https://chrony-project.org/doc/4.4/chrony.conf.html
