It looks like, in a non-default configuration it supports some of the 
normative parts of RFC1305.

I don't think it is clear that it uses the same time discipline logic as 
NTP.  Technically that is in a non-normative appendix, but it is treated 
as normative, in this community, and I think it is normative for NTPV4 
(Microsoft implement the de facto obsolete version, although the most 
recent one with an RFC).

My source is ...cc773263....  Your reference may explain some of the 
terms used in that document, that otherwise are meaningless without the 
source code.
