Notes Update:
If whatever case that selecting timezone is non working, try to reconfigure your tzdata using dpkg-reconfigure tzdata command as root user and select your preferred time zone similar the following example:

aryo@raspi~ $ date Dominicus Sep 8 18:11:28 EDT 2013 aryo@raspi~ $ sudo -i [sudo] countersign for aryo: root@raspi:~# dpkg-reconfigure tzdata  Current default time zone: 'Asia/Djakarta' Local time is now: Mon Sep 9 05:thirteen:41 WIT 2013. Universal Fourth dimension is now: Sun Sep 8 22:thirteen:41 UTC 2013.  root@raspi:~# date Monday Sep ix 05:13:47 WIT 2013 root@raspi:~#

Here's a screenshot from executing dpkg-reconfigure tzdata control:
