NTP - fix massive offset

Question

I've got a RHEL 5.4 and I'm synced to my NTP server .... I have managed to reduce the jitter to almost 0 with

ntpq -q

But then it came right back. The huge offset remains regardless of what I do. I also tried

[root@myHostname ~]# tinker panic 0
-bash: tinker: command not found

I can't find much else on the internet besides the "-q" command because it seems to work for everyone.

this is how bad it is currently:

[root@chtlcprvc1 ~]# ntpq -p
remote           refid      st t when poll reach   delay   offset  jitter

Not sure if you need more information. Thanks for any help.

Solution

It was a Xen VM and I had to use set this in /etc/sysctl.conf:

xen.independent_wallclock=1

then bounce network ... after that I set the time manually with:

date--set="JAN 11 2016 18:00:00"

then ran

service ntpd stop
ntpd -gq
service ntpd start
