Hello,
In able to check your NTP settings you will have to access diagnostic shell from the Main menu (option 4 >> option2).
Once you are at the prompt, login with the maint or root user and you can cat the ntp.conf file
diag@databroker:: cat /etc/ntp.conf
As far as for the commit option, there is one under the main menu (option 3 >> option 7)
Thanks
