Example showing how you configure related settings through the HMC CLI:
```shell
chhmc -c date -s modify --datetime MMDDhhmm # Set current date/time: MMDDhhmm[[CC]YY][.ss]
chhmc -c date -s modify --timezone Europe/Copenhagen # Configure your timezone
chhmc -c xntp -s enable # Enable the NTP service
chhmc -c xntp -s add -a IP_Addr # Add a remote NTP server
chhmc -c date -s modify --timezone Europe/Copenhagen # Configure your timezone
chhmc -c date -s modify --datetime 01301615 # Set current date/time: MMDDhhmm[[CC]YY][.ss]
```
Remember to reboot your HMC after changing the timezone.
