Re: difference between sntp and ntp server

a simple question: Is there a difference between a ntp server and a sntp server? I studied the RFC's, but found no evidence, that for the server side there are differences.

NTP servers are always (give or take version and permission considerations) acceptable to SNTP clients.

An SNTP server behaves the same as a stratum 1, NTP server, supporting only client/server and broadcast modes. It must only be used where an NTP server would be stratum 1 (i.e. early (pre-Windows 2003) versions of w32time cannot legally act as servers).

Earlier version of the SNTP spec permitted more association modes. Earlier versions didn't allowed impending leap seconds to be signalled.
