I'd say let's just install ntpd by default, and stop running ntpdate automatically, because it 1) only runs when (re)connecting, which is kind of misleading and not correct on servers and 2) isn't currently reported in the GUI as automated Internet time sync, while it's actually doing this in the background. The new time & date tool in GNOME Control Center 3.0 also relies on the fact that ntpd is present to sync time.
