Comment (by billerickson):

 What would the array_reverse() be applied to? We're querying for a single
 post ( 'posts_per_page' => 1 ).

 If you have two posts with the same datetime, then the adjacent post will
 always be the other one. Key query_vars:


 {{{
 'posts_per_page' => 1,
 'post__not_in' => array( $this->current_post->ID ),
 'date_query' => array(
   array(
       $date_query_key => $this->current_post->post_date,
       'inclusive' => true,
   )
 ),

 }}}

 Whether you're looking for previous or next, both posts will be included
 due to the inclusive line. And since we're excluding the current post, the
 other post will always be returned.
