Answer 1

Use getFunctions() instead of getFilters()

public function getFunctions()
{
    return array(
        new \Twig_SimpleFunction('server_time_zone', array($this, 'getServerTimeZone')),
    );
}

Twig filters are used to filter some value.

{{ "some value" | filter_name_here }}

Btw, you can define both filters and functions in the same class.
