after seeing `adjtime failed: Invalid argument` in my syslog, I tried using `ntpd -s` but it would trigger `/etc/ntpd.conf: No such file or directory` see https://github.com/NixOS/nixpkgs/issues/31885 Instead of running the daemon with a specific config file, use the standard file so that user are able to use the ntp executable without having to look for the current config file.
