Even though there are several ways of doing this, this is by far the quickest and easiest way of changing the time zone on your Linux installation. Linux looks into /etc/localtime to determine time zone and local time. Here you can place either a time zone file, or just create a symbolic link. Remember that time zone files are located under /usr/share/zoneinfo/
To change the time zone, simply do the following:\n
# rm -fr /etc/localtime # ln -s /usr/share/zoneinfo/Europe/Sarajevo /etc/localtime # reboot
In this example, I’ve used Sarajevo as a reference for the time zone. Replace it with either your city or the nearest larger city in your country.
