NTP not correcting server time

My CentOS server's time is incorrect. Right now, my local time is 17:22. This is what my server reports:

# date
Sat Apr  7 17:37:51 IST 2012

Open in new window


When I run ntpdate, it doesn't seem to correct this:

# ntpdate -v 0.centos.pool.ntp.org
 7 Apr 17:38:46 ntpdate[32076]: ntpdate 4.2.2p1@1.1570-o Fri Nov 18 13:21:21 UTC 2011 (1)
 7 Apr 17:38:47 ntpdate[32076]: step time server 129.128.5.210 offset -891.236361 sec

# date
Sat Apr  7 17:39:25 IST 2012

Open in new window


Is it because the offset is too large? Or is it because it's a Xen based server? How do I fix it?

set NTP on Xen server else all virtual machines will get updated from Xen server time.

XenServer Hosts manage time for all virtual machines (VMs), unless the VMs are specially configured. It is therefore very important to keep time synchronized, especially on VMs that function as domain controllers.

To configure NTP when installing or updating your XenServer, just enter NTP servers in the installation wizard.

To configure NTP on XenServer Host after the installation, perform the following steps:

1. Edit /etc/ntp.conf and add NTP servers

#vi /etc/ntp.conf

2. Add NTP servers at the end of the file in the following format:

server ntp.server

Citrix recommends using the following NTP servers:

0.pool.ntp.org
1.pool.ntp.org
2.pool.ntp.org

3. Restart the NTP service:

#/etc/init.d/ntpd restart

apparently, it's a sort of hybrid server, not 100% sure how it's set up exactly, but it seems the data centre staff need to fix this on their end, so I guess it's out of my hands. Thanks though.
