I installed F19 using the installation DVD. For software sources, I selected GNOME desktop with a few addons (Epiphany, games, dev tools). chrony was not installed. The NTP toggle in gnome-control-center Time & Date panel is broken (you can press it but it doesn't work and will reset itself the next time you visit) and timedatectl fails to set NTP. Everything works after installing chrony manually. chrony was installed by default in F18; I wonder what changed. I also wonder what the best way to fix this would be, without requiring any user intervention.
It used to be installed conditional on the installation of system-config-date.; since that's not part of GNOME any more, it's not pulled in. I've fixed this in the metadata for F-20; we could pull back the fix to F-19.
... and done for F19 too.
I guess this can be closed?
