I have a custom post type where the posts have a start date and an end date. These are saved to the database as Unix timestamp/Epoch. I want to create a column for this custom post type called Active where I want to show a green icon when the current date and time is between the start and end date.

How do I pull the metadata and compare them to the current date/time and if true display a green icon, if not a red icon?

I have this function which does almost the same thing but for search results. But I cannot figure out how to use this in a column:

function filter_search_results( $search_query ) 
$time = current_time( 'timestamp' );
 if ( $search_query->is_search ) 
 $search_query->set( 'meta_query', array(
 'relation' => 'AND',
 array(
 'key' => 'visitor-start-date',
 'value' => $time,
 'compare' => '<='
 ),
 array(
 'key' => 'visitor-end-date',
 'value' => $time,
 'compare' => '>='
 ),
 ) );
 

add_action( 'pre_get_posts', 'filter_search_results' );

I solved it:

 if ( 'visitor_active' == $column_name ) 
 $start_date = get_post_meta( $post_id, 'visitor-start-date', true );
 $end_date = get_post_meta( $post_id, 'visitor-end-date', true );
 $current_time = current_time( 'timestamp' );
 if ($start_date < $current_time && $end_date > $current_time) 
 echo '<span class="dashicons dashicons-yes" style="color:#75c377;"></span>';
 
 else 
 echo '<span class="dashicons dashicons-no" style="color:lightgray;"></span>';
 
 

Don't know if this is the best way to do it though?
