*SOLVED* Time difference between hwnode and vps [message #9031]

Hi All,

While I did see this question was asked. I didn't see a clear answer on this topic. I have a hwnode running RHEL4 and vps's all running CentOS 4. All I want is my vps's to have the same time as the HW node. In fact, I'm surprised this isn't the default. Is there a simple command to accomplish this? The manual suggests setting up a separate vps just to do NTP, which is ridiculous.

Your timezone in the VPS is MSK; this likely differs from your HN.

During the redhat/centos installer, you choose the timezone for your HN. The VE template has its own preconfigured timezone. So, its very possible for the zones to differ.

To resolve the problem, You should configure your VE to have the same timezone as the HN. For example, if EST is your preferred timezone:

rm -rf /etc/localtime 2>/dev/null; unlink /etc/localtime 2>/dev/null
ln -s /usr/share/zoneinfo/EST /etc/localtime
vzctl exec 1041 rm -rf /etc/localtime 2>/dev/null
vzctl exec 1041 unlink /etc/localtime 2>/dev/null
vzctl exec 1041 ln -s /usr/share/zoneinfo/EST /etc/localtime

You can find many more exciting timezones with:

find /usr/share/zoneinfo/ | more

Hope this helps!
Rick

Good info, thanks! Here is a script that will do this for all your VE's on a given hardware node:

#! /bin/bash
#for f in 103 305 801 802 811 820 1037 2207 2209 2210
for f in `ls /vz/private`
do
vzctl exec $f rm -rf /etc/localtime 2>/dev/null
vzctl exec $f unlink /etc/localtime 2>/dev/null
vzctl exec $f ln -s /usr/share/zoneinfo/CST6CDT /etc/localtime
done
