Antwort: Re: [rhn-users] listen to a timeserver with ntp,continuously sync the time on a running sys

[Brian T. Brunner]

If you have NO time server, and must manually set the clock on one system 
in a site that the other systems will sync to, hwclock is the correct tool for 
setting time on that "blind guide".

Once hwclock has been used to set the system and hardware clocks, ntp no longer 
functions (you're doing it yourself, I'll stay out of your way) until the next reboot.

So
service ntp stop
date (to set)
hwclock --systohc
service ntp start

seems to be getting us what we need.

(nb this is memory of lessons learned a few months ago. I'll
dig up precise details if needed).

Could you please explain what you do with hwclock, because this is a tool 
to set the hardware clock (thats what hwclock stays for).
I'm not really sure how to sync continuously with a time server using 
hwclock.

Having wrestled with this same beast, I discovered that 
using hwclock after ntpd starts running will cause ntpd to 
stop operating. Rebooting cures this until hwclock is again used,
This might not be related to your problem but it was to mine.

I am having the same problem with ntpd. I have tried to sync to different 
servers with no luck. This is my main dns server that all other servers 
sync to, I hope someone finds something. Thanks
