1. Login to the main host node.(SSH).

2. Stop the node(container) which you want to set time.

3. Set the container to have capability to change the time zone.

vzctl set VZID -–capability sys_time:on –-save

For example

~]# vzctl set 11 –capability sys_time:on –save
CT configuration saved to /etc/vz/conf/11.conf
[@~]#

4. Start the container.

vzctl start VZID

5. Login in to the container and Change your local timezone.
   To find correct time zone location, do this command to search exiting timezones
