Modify the date and time format and add “updated”

Hi Edilson

Thanks for reaching out.

This is, unfortunately, a reasonably technical task to complete. If you have some development experience it’s something you could try, otherwise, you could hire a developer to assist. We recommend Codeable.

To achieve this yourself you’d need a child theme:

https://siteorigin.com/wp-content/uploads/2015/03/vantage-child-starter.zip

Once activated you’d then copy the following function into your child theme functions.php file:

if ( ! function_exists( 'vantage_posted_on' ) ) :
/**
 * Prints HTML with meta information for the current post-date/time and author.
 *
 * @since vantage 1.0
 */
function vantage_posted_on() {
	$date_time = '<a href="%1$s" title="%2$s" rel="bookmark"><time class="entry-date" datetime="%3$s">%4$s</time></a><time class="updated" datetime="%5$s">%6$s</time>';
	$date_time = sprintf( $date_time,
		esc_url( get_permalink() ),
		esc_attr( get_the_time() ),
		esc_attr( get_the_date( 'c' ) ),
		apply_filters('vantage_post_on_date', esc_html( get_the_date() )),
		esc_attr( get_the_modified_date( 'c' ) ),
		esc_html( get_the_modified_date() )
	);

	$author = sprintf('<span class="author vcard"><a class="url fn n" href="%1$s" title="%2$s" rel="author">%3$s</a></span>',
		esc_url( get_author_posts_url( get_the_author_meta( 'ID' ) ) ),
		esc_attr( sprintf( __( 'View all posts by %s', 'vantage' ), get_the_author() ) ),
		get_the_author()
	);


	$comments_link = '<span class="comments-link"><a href="' . get_comments_link() . '">' . get_comments_number_text( 'Leave a comment' ) . '</a></span>';

	$posted_on_parts = array(
		'on' => sprintf( __( 'Posted on %s', 'vantage'), $date_time ),
		'by' => sprintf( __( '<span class="byline"> by %s</span>', 'vantage' ), $author),
		'with' => ' | ' . $comments_link
	);
	$posted_on_parts = apply_filters( 'vantage_post_on_parts', $posted_on_parts );

	$posted_on = implode(' ', $posted_on_parts);
	echo apply_filters('vantage_posted_on', $posted_on);
}
endif;

From there you’d edit the function as required. An intermediate level task.

For sure :) Hope you’re able to make progress.
