If you want to change your server's time zone to to make it convenient for you, you can do so easily by following these steps:
1.) delete the current time zone setup and use the command "rm /etc/localtime"
2.) Create a symlink to the desired time zone with "ln -s /usr/share/zoneinfo/Africa/Cairo/etc/localtime" (where Africa/Cairo is the desired time zone!)
If you type "date," you can see that the time zone has been changed!
