Hm, yes, having two similar but not identical implementations of the
timedate interface and using one only when an NTP package is installed
could be a source of confusion.

Beside the selection of the NTP service that should enabled/disabled,
there are some minor differences in the functionality. For instance,
when setting the time, timedatex compensates for the time spent in the
polkit authorization check. E.g. running "timedatectl set-time 12:00:00"
and taking 5 seconds to type the password sets the clock to 12:00:05,
not 12:00:00.

Would it make more sense to always use timedatex in Fedora, even when
no NTP package is installed?
