Just curious, it appears you have native DNS, why do you need to proxy NTP over APRS (unless you use a similar technique for DNS).
BTW, at startup our project always steps the time using (8 second timeout would be too low for you):
--
chronyd -q -t 8 "server time.example.tld iburst"
--
before starting "chronyd" in the background. (no systemd).
