Same behaviour here. It worked well under dapper and only became broken after an upgrade to edgy.
Under dapper i was still required to enter the admin password whenever i wanted to change time-settings using the [Time-admin], in edgy however this is no longer required. Therefore i suspect it has something to do with writing permissions on the "/etc/ntp.conf" file. (note that a manual "sudo vi /etc/ntp.conf" to add the servers does indeed work) -- [time-admin] The time server that added the last time doesn't exist when open time and date again https://launchpad.net/bugs/55582 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
