As it turns out, it's called msntp and it is already part of m0n0wall, 
acting as a client...

Looks like to get it to serve, you only need minor surgery to 
system_ntp_configure() , /usr/local/bin/runmsntp.sh, and 
services_dhcpd_configure(). To get it above the kludge level, you'll 
also need some UI work and some smart things with firewall rules.

Personally I'm quite happy running ntp server(s) behind m0n0wall, and 
lacking any php experience or coding clout, I'll gladly leave it to 
properly motivated people (for instance the guy that wanted the feature 
in the first place?) ;-)
