If you're like us, you'll want your server's timezone to match your local time to make log management easier. Fortunately, this is easy to do! This guide works perfectly on servers running CentOS and may vary on other Linux distributions.
In the above example, we've taken a backup of the /etc/localtime file, and adjusted the timezone to Europe/London.
mv /etc/localtime /etc/localtime.bak
ln -s /usr/share/zoneinfo/Europe/London /etc/localtime
To make this change permanent, you need to edit the file /etc/sysconfig/clock and add the entry ZONE="Europe/London" and save the file. This will keep the time zone even after the server reboot.
