2 x date format on Blog post

@dewice, @steveax, and @w.reidlinger, I found a temporary solution add these two functions to your Child Theme and either comment out or remove all reference to get_the_modified in whatever version. The code below is a functioning example.

/***********************************TEMP BUG FIX UNTIL UPDATE************************************************

	function shapely_posted_on() {
		$time_string = '<time class="entry-date published updated" datetime="%1$s">%2$s</time>';
		//if ( get_the_time( 'U' ) !== get_the_modified_time( 'U' ) ) {
		//	$time_string = '<time class="entry-date published" datetime="%1$s">%2$s</time><time class="updated" datetime="%3$s">%4$s</time>';
		//}

		$time_string = sprintf(
			$time_string,
			esc_attr( get_the_date( 'c' ) ),
			esc_html( get_the_date() )
		//	esc_attr( get_the_modified_date( 'c' ) ),
		//	esc_html( get_the_modified_date() )
		); ?>

		<ul class="post-meta">

		<li><i class="fa fa-calendar"></i><span class="posted-on"><?php echo wp_kses_post( $time_string ); ?></span></li>
		<?php shapely_post_category(); ?>

		<?php
		echo ( is_archive() ) ? '<hr>' : '';
	}
