## Configure date/time through CLI
|
|
|
|
|
|
|
|
|
|
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
|
|
|
|
|
```
|
|
|
|
|
Remember to reboot your HMC after changing the timezone.
