Setting the time zone for a cluster
You can manually set or modify the time zone for a cluster by using the Edit Date and Time dialog box in System Manager. You can also add time servers to the cluster.
Network Time Protocol (NTP) is always enabled on a cluster. You can disable NTP by contacting technical support. However, disabling NTP is not recommended.
You can add the IP addresses of the NTP server at your site. This server is used to synchronize the time across the cluster.
You can specify either an IPv4 address or an IPv6 address for the time server.
In the Setup panel, click Date and Time.
In the Edit Date and Time dialog box, select the time zone.
Specify the IP address of the time servers, and then click Add.
Verify the changes that you made to the time settings in the Date and Time window.
