This is the code I’m using:
<nav class="nav">
<ul>
<li>
<?php previous_post_link_plus( array(
'order_by' => 'post_date',
'post_status' => 'future, publish',
'loop' => true,
'end_post' => false,
'thumb' => false,
'max_length' => 0,
'format' => '%link',
'link' => '<span class="uline">Previous</span> %title <span class="pndate">%date</span>',
'date_format' => 'd.m.y',
'tooltip' => '%title - %date',
'ex_cats' => '',
'ex_cats_method' => 'weak',
'num_results' => 1,
) ); ?>
</li>
<li>
<?php next_post_link_plus( array(
'order_by' => 'post_date',
'post_status' => 'future, publish',
'loop' => true,
'end_post' => false,
'thumb' => false,
'max_length' => 0,
'format' => '%link',
'link' => '<span class="uline">Next</span> %title <span class="pndate">%date</span>',
'date_format' => 'd.m.y',
'tooltip' => '%title - %date',
'num_results' => 1,
) ); ?>
</li>
</ul>
</nav><!-- .nav -->
