Changing the time zone on a Nutanix cluster

---

We must first check the cluster’s current time zone.

nutanix@NTNX-20SM57030209-A-CVM:200.86.244..11:~$ ncli cluster info

Cluster Id                : 000XXXXX-d7d8-XXXX-639b-XXXXXXXXX::XXXXXXXXXXXXXXX
Cluster Uuid              : 000XXXXX-d7d8-XXXX-639b-XXXXXXXXX
Cluster Name              : CLS01-XXXX
Cluster Version           : 6.8.1

Cluster FQDN              : cls01-XXXX.XXXXXX.com.br

Then we check all the cluster nodes to ensure they are all in the same time zone.

When we confirm the need, we can change the time zone of the entire cluster with the command below.

ncli cluster set-timezone timezone=NEW_TIME_ZONE

Example: America/Sao_paulo
