NTP server available as a homebrew service?

I found https://formulae.brew.sh/formula/ntp but the documentation points to the plain ntp documentation. What i am looking for is to be able to start and stop an NTP server on my local machine using the brew services command.

Any hints or URLs where i can read up on how to achieve that?

You can look at how the nginx formula does it: https://github.com/Homebrew/homebrew-core/blob/master/Formula/nginx.rb#L136-L159

Adding a proper def plist to the ntp formula should do it.
