Msntp is intended to be a straightforward sntp (simple network time protocol) daemon/utility that is easy to build on any reasonable unix platform (and most near-unix ones), whether or not it has ever been ported to them before. it is intended to answer the following requirements, either by challenge and response or the less reliable broadcast method:

a simple command to run on unix systems that will check the time and optionally drift compared with a known, local and reliable ntp time server. no privilege is required just to read the time and estimate the drift.

a client for unix systems that will synchronise the time from a known, local and reliable ntp time server.

a server for unix systems that are synchronised other than by ntp methods and that need to synchronise other systems by ntp. it is not intended to work as a peer with true ntp servers, and won't.
