The cluster time zone is a setting that determines the time zone used by all CVMs in the cluster. The cluster time zone affects the timestamps of Nutanix logs, events, alerts, and reports. The cluster time zone also affects the scheduling of tasks such as snapshots, replication, and upgrades. By default, the cluster time zone is set to UTC (Coordinated Universal Time) when the cluster is created3.
To change the cluster time zone, the administrator needs to use the ncli (Nutanix command-line interface) on any CVM in the cluster. The steps are as follows4:
* Log in to any CVM using SSH.
* Run ncli cluster get-timezone to check the current cluster time zone.
* Run ncli cluster set-timezone timezone=<timezone> to change the cluster time zone, where <timezone> is a valid time zone identifier (for example, America/New_York).
* Run ncli cluster get-timezone again to verify that the cluster time zone has been changed.
Note that changing the cluster time zone does not affect the time zone of Prism Element or Prism Central VMs. To change their time zone, the administrator needs to use Prism Element UI or Prism Central UI respectively5.
