The GUI lets me change the fields to what ever I want but the GUI resets the NTP server and Continous Check box back to the System console setting and leave the time zone set to Europe/Berlin.

No matter what I do I cannot control the time zone.

This may be related I am trying to use the NAS function. I am getting "Time differences between NAS and KDC are too large"

and

Cannot renew kerberos ticket

I have the time set to manual and it is within a couple of seconds of the domain controller.
