Can add this coding in single.php?

To whom may concern,
Can I add this coding in front of <?php the_time( get_option( ‘date_format’ ) ); ?> in single.php?

class=”comm_date post-date updated”

The missing required field “updated” and “author” in the Structured Data errors of Google Webmaster Tools are increasing when my post getting more. I was trying to fix them as worry it may affected my website ranking.

It would be much appreciated if you could advise how to solve the missing “author” issue.

thanks & regards,
Irene
