Change Timezone in CentOS | Cambiar el timezone en Centos

First, make a backup of the existing localtime file. It’s always good practice to make backups of original config files.

[gaarai@server ~]$ sudo mv /etc/localtime /etc/localtime.bak

Next, create the link:

[gaarai@server ~]$ sudo ln -s /usr/share/zoneinfo/America/Chicago /etc/localtime

Make sure to replace America/Chicago with the directory (if your zone has one) and filename of the timezone you wish to use.

Now you just need to test your change. Run date from the command line, and ensure that the appropriate time, date, and timezone are reported.
