Scroll down until you see "Local timezone" and then select your timezone in the drop-down list.
NOTE: Timezones are sorted alphabetically by the name of continent/location and not by UTC +/-.
Click the “Save” button next to your chosen timezone to apply changes.
You should see the message “Your preferred display timezone has been changed to…” if it was changed successfully.
