Which version of Debian is this? I'm guessing it's fairly recent, because ntpsec is fairly recent. In the most recent version or two, systemd-timesyncd is a separate package, and it cannot coexist with chrony (they both provide the "time-daemon" virtual package). So, if this is Debian 12 (maybe 11 also, dunno about older), then when you installed either ntpsec or chrony, it should have removed the systemd-timesyncd package. You should be able to verify that the systemd-timesyncd package is removed. In some older versions of Debian, systemd-timesyncd was part of the systemd package, and was always installed, even if you installed ntp or chrony. In these versions, the systemd unit file for timesync had checks for the existence of the binaries belonging to ntp, chrony and openntpd, and would prevent timesync from running if any of those was found. I don't remember which version did which thing. And of course, if you are not actually running Debian, then all bets are off. You're on your own with Armbian, Raspbian, etc.
