Hmm, not sure how to change my code in order to use those examples.. Could you alter this code?
<?php
$args = array(
'meta_key' => 'antallningsdatum',
'orderby' => 'meta_value_num',
'order' => 'DESC'
);
$author_query = new WP_User_Query( $args );
$authors = $author_query->get_results();
$user_id = get_the_author_meta('ID');
foreach( $authors as $author ):
echo '<li class="anstallningsdatum">'. get_the_author_meta( 'antallningsdatum', $author->ID ).'</li>';
;?>
<?php endforeach;?>
