Changing Time zone in CentOS server/ Cpanel/WHM Servers

Option :1

Main >> Service Configuration >> PHP Configuration Editor [Date and Time] we can change

Changing the time in VPS via  WHM  Main >> Server Configuration >> Server Time,

Option 2:

Editing the configuration Files

#cat /etc/sysconfig/clock

date.timezone="US/Chicago"

date.timezone="America/Chicago"

 [~]# cat /etc/sysconfig/clock
ZONE="US/Central"
UTC=false
ARC=false

Option 3:

# ls -la  /etc/localtime

# cp /etc/localtime /etc/localtime.bkp

# cp /usr/share/zoneinfo/America/Chicago /etc/localtime

Or

#  ln -s /usr/share/zoneinfo/America/Chicago /etc/localtime

And then update the time zone value in your php.ini file 

date.timezone="America/Chicago" 

Restart the apache and check your server time.

Option 3:

Sometimes if your server is vps then the above options will not be work , for that time you can do the following steps.

1. Directly set the time using the date command, You can get the right time from your other server.

 date --set="2012-10-17 21:34 am"

and if it throws  "step-systime operation not permitted" error please fix this issue from your Hardware Node.

 # vzctl stop VEID

# vzctl set --capability sys_time:on --save

 # vzctl restart VEID

 date --set="2012-10-17 21:34 am"

Another fix:

 yum -y install ntp

Identify time zone from http://www.pool.ntp.org/

# vi /etc/ntp.conf

select a server.

eg: 0.centos.pool.ntp.org

# ntpdate servername
That is ntpdate clock.rethat.com


While doing the ntpupdate you may receive the following error:  "step-systime operation not permitted"

Suggested Fix

# vzctl stop VEID

# vzctl set --capability sys_time:on --save

needs to be replaced by your container’s ID
After executing the command above, your container’s configuration file needs to be reloaded. Thus, use ‘vzctl‘ to restart it.

# vzctl restart
