Change formatting of Date parameter on custom post type

Use the post_date_column_time filter to change the time format. The documentation says it changes the “published time of the post”, but it will change the scheduled time as well (ticket).

Tested:

add_filter( 'post_date_column_time', static function ( $time, $post ) {
    if ( 'wp_events' !== get_post_type( $post ) || 'future' !== get_post_status( $post ) ) {
        return $time;
    }

    return sprintf(
        __( '%1$s at %2$s' ),
        get_the_time( __( 'F jS, Y' ), $post ),
        get_the_time( __( 'g:iA' ), $post )
    );
}, 10, 2 );
