If an NTP package is installed, systemd-timesyncd is not used. It just never starts. On my system, it's not even installed. After digging around a bit, I think Debian has changed something on me, which I didn't notice until now. In older versions of Debian, systemd-timesyncd and ntp (or chrony, etc.) would coexist. systemd-timesyncd.service was configured so that the daemon wouldn't be started if any of the other NTP daemons existed on the system. I can no longer see that in the systemd-timesyncd.service file (which I'm viewing as <https://salsa.debian.org/systemd-team/systemd/-/blob/debian/master/units/systemd-timesyncd.service.in> because it's not on my system). Instead, the ntp and systemd-timesyncd *packages* now appear to have Provides: time-daemon which might make them mutually exclusive.
