lets go over a couple of things to help lower the grumpiness of others.
1) Who are you?
2) What is your position in regards to knowing ntpd and/or chrony in
stability and other things?
I think most people do not know who maintains ntpd, and do not know if
this is a "Oh wow I just found this really great software program and
we should change to it right away!!!!" kind of email.

Ok time is one of those touchstone security tools that people get all
kinds of crazy about when things get changed. Here are a couple of
questions that might help:
1) Why chrony? Why not OpenNTPD [fill in the blank here]
2) Where is the data that chrony actually controls the clock better?
3) How far have you/others tested it in comparison with ntpd?
4) A release plan should probably look like the following:
Fedora-14 we add chrony into alternatives or other commands needed to
get it to work. System-config-date has pathways to configure one or
the other when it is seen. Test days and reviews are done to see how
it is going. Organize a short-term sig and get Mo to make a design for
shirts (melting clocks sounds a good idea). People who test, find
bugs, etc etc qualify for a drawing of stuff.
Fedora-15 from feedback we have gotten on chrony, we go through the
plan of making chrony default (or not) and make ntpd optional.
This is one alternative plan ( a bit slow but for security related
things probably better.). To speed it up we need to move get people
motivated towards 12/13 testing and feedback.
