     * @var array
    private static $db = array(
        'UserTimeZone' => 'TimeZone'

     * @return FieldList
    public function getCMSFields()

        // ...

                'My time zone'

        return $fields;

Format of time zone

You can change the default format of the time zone in the dropdown menu by creating a file mysite/_config/timezone.yml and adding e.g.

      format: '%Name (%Region)'

You can use 'Name', 'Region' and 'Identifier' in the string and it will be replaced proper.
