The Time Zone Database (called tz, tzdb or zoneinfo) contains code and data that represent the history of local time for many representative locations around the globe. 0
Begin by first verifying that you have tzdata installed:
$ kiss b tzdata
$ kiss i tzdata
Look for the available timezones in /usr/share/zoneinfo/:
$ ls /usr/share/zoneinfo
Write your preferred timezone to the /etc/timezone file:
$ echo "TZ" > /etc/timezone
Remember to replace TZ with with your preferred timezone. For example, if I lived in the US Eastern timezone, I would replace TZ with “US/Eastern”.
Lastly, copy the preferred timezone file to /etc/localtime:
$ cp TZ_PATH /etc/localtime
Remember to replace TZ_PATH with with the complete timezone path. For the example given above, the complete TZ_PATH for “US/Eastern” would be “/usr/share/zoneinfo/US/Eastern”.
As an optional final step, remove the tzdata package.
$ kiss r tzdata
