My Vera is internal only (no internet access, prevented by Firewall). Anytime I disconnect Vera (say to pair with a z-wave device), I lose the time/date (since it can’t connect to get time from the internet).
So - I followed the steps in the wiki here: http://wiki.micasaverde.com/index.php/Time_Syncronization
After that, I edited /etc/config/ntpclient to add my Domain Controller (Windows Server 2008R2 that’s running a Time Service).
Starting the client failed - because of a lack of trust between the two machines.
The NTP client has a -t option switch that lets you “trust” the connection (not really recommended, from what I understand). After much digging, I found that if I edit the file: /etc/hotplug.d/iface/20-ntpclient
and put a -t option on the two command lines, the start works fine.
Putting this here - in case anyone else with an internal only Vera has the same issue/setup.
