Update "functions.php" to support Google Structured Data

To resolve an error in Google Structured Data this code must be corrected (row 1548 and 1550):


<?php if( ! is_singular() ) : ?>
<span class="entry-date">" rel="bookmark" title="<?php the_title_attribute(); ?>"><?php the_time( get_option( 'date_format' ) ); ?></span>
<?php else : ?>
<span class="entry-date"><?php the_time( get_option( 'date_format' ) ); ?></span>
<?php endif; ?>


With these

<?php if( ! is_singular() ) : ?>
<span class="entry-date updated">" rel="bookmark" title="<?php the_title_attribute(); ?>"><?php the_time( get_option( 'date_format' ) ); ?></span>
<?php else : ?>
<span class="entry-date updated"><?php the_time( get_option( 'date_format' ) ); ?></span>
<?php endif; ?>


“updated” in date class.
