Changing Timezone, Centos Apache server

I'm trying to change my server's timezone.

I was following this tutorial but I can't get it to change to Pacific Standard Time.

ln -sf /usr/share/zoneinfo/EST localtime

Will work, but

ln -sf /usr/share/zoneinfo/PST localtime

will not. What's going on here?

You have to do two things: edit /etc/sysconfig/clock, you will need to change the ZONE variable. And once you've changed it, next time you reboot your CentOS it will apply the change.

To apply it inmediately you need to change the /etc/localtime, i.e.

ln -sf /usr/share/zoneinfo/PST8PDT /etc/localtime

That will make the change immediate, but remember to also edit /etc/sysconfig/clock so your change won't be undone in next reboot.

# yum -y install system-config-date
# system-config-date

Try ln -sf /usr/share/zoneinfo/US/Pacific localtime

From CentOS7 onwards:

timedatectl set-timezone US/Pacific

The question doesn't specify CentOS version, and there is no /etc/sysconfig/clock anymore on a default CentOS 7 (RHEL 7).
