(not very secure), so I have to keep changing it to be the local server.

Well, none that have been reported by anyone other than myself when asking questions in the first place about it. But none opened a bug about it because it's "not a bug" even though it is, (in my personal opinion) a very big bug to have EVERY GUEST contact pool.ntp.org every 10 minutes. wether it's a guest that's behind a proxy, or the proxy itself, or the net vm. This is a security concern, and a big one at that. for all unix types, the clock VM should contact the NTP server once every 6 hours (or on boot and then every 6 hours), and every guest should be updated by that guest for time, unless set to otherwise update from elsewhere. I have my own NTP server, and yet I install things, and I just want to capture all NTP from everything behind the NetVM and make it all get the NTP from the NetVM.
