Are you running NetworkManager?

This is a problem with NetworkManager.  It starts AFTER ntpd.  The fix 
is to cause ntpd to start after NetworkManager but that is not a good 
solution in my mind.

You are also supposed to be able to declare a server as 'dynamic' in 
/etc/ntp.conf.  This does not seem to correct the problem for me.

So, two options remain:

1. modify /etc/init.d/ntpd to start later.
2. start ntpd from rc.local, which runs last.

Personally I hate to modify system files that I then have to track over 
releases.  In either case, here, this is necessary. :(

It is my opinion that the ntpd maintainer needs to start ntpd AFTER 
NetworkManager.

ntpd is: 58

NetworkManager is: 98

99 is sorta conventionally held for local customized startups scripts, 
so I don't know what would be best.  Obviously the NetworkManager 
maintainers feel the need to start as close to the end as reasonable.

So, I guess its best to:

# /sbin/chkconfig ntpd off

and then edit /etc/rc.local and add:

service ntpd start

to then end of it.

Good Luck!
