Here’s how to change time zone for system date on your CentOS web server:
Go into the directory zoneinfo:
cd /usr/share/zoneinfo
Then find the right zone file for you such as for me Los Angeles is for PST (Pacific Standard Time), which is here:
/usr/share/zoneinfo/America/Los_Angeles
Then simply copy over that file to /etc/localtime like this:
cp /usr/share/zoneinfo/America/Los_Angeles /etc/localtime
Run the date command:
date
and you should get something like:
Wed Jul 6 16:56:47 PDT 2011
Instead of the other time zone you were getting.
