System Status Word always show "sync_unspec"
On Ubuntu 24.04 using ntpsec installed from Ubuntu repos, querying the system variables with 'ntpq -c rv' always shows 'sync_unspec' even though the system seems to be in sync with an NTP server.
Expected value is 'sync_ntp'.
'ntpq -pn' show that the system is in sync:
$ ntpq -pn
