Blog post date not in format required by schema.org

Not sure what responsive_child_post_meta_data() is but I use this and it validates just fine:

<time itemprop="datePublished" class="published" datetime="<?php echo get_the_time('c'); ?>" content="<?php echo get_the_time('c'); ?>">
    <?php echo get_the_date(); ?>
</time>
