Hi Jesper. Thanks for your help with this. Turns out the code I was using for the date meta-boxes was causing other problems with the site too, so I’ve started using Advanced Custom Fields instead for that – which is a lot simpler and works great with your plugin, the date admin column now works. Thanks for your time, appreciate it.

Here’s the screenshot. First post is working, then nothing.

Code I’m using in functions.php to gather & store the dates is below:

function ep_eventposts_metaboxes() {
    add_meta_box( 'ept_event_date_start', 'Start Date and Time', 'ept_event_date', 'auction', 'side', 'default', array( 'id' => '_start') );
    add_meta_box( 'ept_event_date_end', 'End Date and Time', 'ept_event_date', 'auction', 'side', 'default', array('id' =>'_end') );
}
add_action( 'admin_init', 'ep_eventposts_metaboxes' );
// Metabox HTML
function ept_event_date($post, $args) {
    $metabox_id = $args['args']['id'];
    global $post, $wp_locale;
    // Use nonce for verification
    wp_nonce_field( plugin_basename( __FILE__ ), 'ep_eventposts_nonce' );
    $time_adj = current_time( 'timestamp' );
    $month = get_post_meta( $post->ID, $metabox_id . '_month', true );
    if ( empty( $month ) ) {
        $month = gmdate( 'm', $time_adj );
    }
    $day = get_post_meta( $post->ID, $metabox_id . '_day', true );
    if ( empty( $day ) ) {
        $day = gmdate( 'd', $time_adj );
    }
    $year = get_post_meta( $post->ID, $metabox_id . '_year', true );
    if ( empty( $year ) ) {
        $year = gmdate( 'Y', $time_adj );
    }
    $hour = get_post_meta($post->ID, $metabox_id . '_hour', true);
    if ( empty($hour) ) {
        $hour = '10';
    }
    $min = get_post_meta($post->ID, $metabox_id . '_minute', true);
    if ( empty($min) ) {
        $min = '30';
    }
    $month_s = '<select name="' . $metabox_id . '_month">';
    for ( $i = 1; $i < 13; $i = $i +1 ) {
        $month_s .= "\t\t\t" . '<option value="' . zeroise( $i, 2 ) . '"';
        if ( $i == $month )
            $month_s .= ' selected="selected"';
        $month_s .= '>' . $wp_locale->get_month_abbrev( $wp_locale->get_month( $i ) ) . "</option>\n";
    }
    $month_s .= '</select>';
    echo '<input type="text" name="' . $metabox_id . '_day" value="' . $day  . '" size="2" maxlength="2" />';
    echo $month_s;
    echo '<input type="text" name="' . $metabox_id . '_year" value="' . $year . '" size="4" maxlength="4" /> @ ';
    echo '<input type="text" name="' . $metabox_id . '_hour" value="' . $hour . '" size="2" maxlength="2"/>:';
    echo '<input type="text" name="' . $metabox_id . '_minute" value="' . $min . '" size="2" maxlength="2" />';
}
// Save the Metabox Data
function ep_eventposts_save_meta( $post_id, $post ) {
    if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE )
        return;
    if ( !isset( $_POST['ep_eventposts_nonce'] ) )
        return;

        return;
    // Is the user allowed to edit the post or page?
    if ( !current_user_can( 'edit_post', $post->ID ) )
        return;
    // OK, we're authenticated: we need to find and save the data
    // We'll put it into an array to make it easier to loop though
    $metabox_ids = array( '_start', '_end' );
    foreach ($metabox_ids as $key ) {
        $events_meta[$key . '_month'] = $_POST[$key . '_month'];
        $events_meta[$key . '_day'] = $_POST[$key . '_day'];
            if($_POST[$key . '_hour']<10){
                 $events_meta[$key . '_hour'] = '0'.$_POST[$key . '_hour'];
             } else {

    }
    // Add values of $events_meta as custom fields
    foreach ( $events_meta as $key => $value ) { // Cycle through the $events_meta array!
        if ( $post->post_type == 'revision' ) return; // Don't store custom data twice
        $value = implode( ',', (array)$value ); // If $value is an array, make it a CSV (unlikely)
        if ( get_post_meta( $post->ID, $key, FALSE ) ) { // If the custom field already has a value
            update_post_meta( $post->ID, $key, $value );
        } else { // If the custom field doesn't have a value
            add_post_meta( $post->ID, $key, $value );
        }
        if ( !$value ) delete_post_meta( $post->ID, $key ); // Delete if blank
    }
}
add_action( 'save_post', 'ep_eventposts_save_meta', 1, 2 );

Thanks for your help.

In case anyone else stumbles across this I’ve actually just narrowed it down to some code I was using to strip out some comments functionality.
