Part LVI. Simple Network Time Protocol Client

The SNTP package provides implementation of a client for RFC 2030, the Simple Network Time Protocol (SNTP). The client listens for broadcasts or IPv6 multicasts from an NTP server and uses the information received to set the system's time of day clock. This will be either the POSIX CLOCK_REALTIME clock or the wallclock device, or both, depending on the configuration. It can also be configured to send SNTP time requests to specific NTP servers using SNTP's unicast mode.

Note that this package predates the existence of the Common Clock Services and has not yet been adapted to use that package's services. Also this implementation is wholly separate to that of the NTP Client.
