How often do we make changes to ntp-stable? Do we generate a new
snapshot every night? If so, then I think that incrementing the
third digit with each snapshot would probably not be such a great

Fair enough. I can see that we need some sort of mechanism of
determining precisely which version of ntp-release/ntp-stable someone
is running, and I think we should differentiate this from ntp-dev.
If we change ntp-stable relatively infrequently, then
incrementing the third digit should be sufficient. If we change it
frequently, I'm not sure what would work best. And I'm not sure
precisely what we should take to be "infrequently" versus
"frequently". Is ten times a year too often? Twenty? I dunno.
But I'd like to see an ISO date-based scheme for ntp-dev.
I'm thinking of something similar to the FreeBSD or postfix
release numbering schemes, but not quite exactly the same as either.
Maybe X.Y.0 would always be an official "ntp-release" version,
whereas X.Y.Z (where Z>0) would be an ntp-stable update, and
X.Y-yyyymmdd would be an ntp-dev snapshot.
People would be able to tell at a glance which version you were
running, and would be able to easily determine when that version was
created, and therefore which code was or was not included.

I've read that several times in the past. Have you already made
changes here to describe your proposed scheme?
