That definition excludes OpenNTP and early versions of W32Time, neither
of which exits after setting the time and both of which are only SNTP.

A crude definition is an NTP client is mandated to implement most of one
of the NTP RFCs (parts of version 3 are non-normative), in respect of
issuing client requests and responding to server responses. An SNTP
client need implement only a small part of an SNTP RFC.
