I've written a tutorial explaining how to check, change and update the timezone information in Linux using several methods, including manual changes, symbolic links, tzselect and tzdata-update utilities, sysconfig clock information, and more. Have fun. http://www.dedoimedo.com/computers/linux-timezone.html Cheers, Mrk
Not necessary. Every Linux distro has a graphical interface for setting up time/date and time zone information. The tutorial is useful though for frequent flyers who need to constantly readjust the settings. For most folks, its set up once and forget it. Since the task was already performed at installation. Post-installation, it may be critical to set up and configure the NTP daemon so the clock stays synchronized with Internet time servers. Pretty much every one knows the time zone they live in or to where they might contemplate traveling.
