Needed an #NTP server on a Raspberry Pi. To keep it light, I chose #OpenNTPD.
Not a great idea.
If your clock is off by more than 180 seconds, it won't adjust it; logs say
adjtime failed: Invalid argument
Now, according to the man page, it will jump to adjust larger offsets on startup, but apparently #Debian has patched this to require adding `-s` to /etc/default/openntpd.
They also don't support `constraint from` config stanzas used to get a trusted date via HTTPS.
Trying #chrony now.
