Time Zone
Time Zone setting is very important as e.g all your logfile entries will be based on the configured zone. Without proper time zone configuration it will be very difficult to compare logfiles from different systems.
Specify the systems <timezone> as the Region/Location that best defines your location. For example, specifying US/Pacific sets the time zone to US Pacific time.
Command completion can be used to list available time zones. The adjustment for daylight time will take place automatically based on the time of year.
