How do I hide date in Google snippet using PHP?

I want to hide the date in my Google snippet and I currently use Yoast SEO plugin. I couldn't change there so I thought I could change it myself. I notice you have the 'the_date' function in 9 matches across 7 files. However, I thought I can use Javascript instead of PHP.

<?php the_time('F jS, Y') ?>

I can replace with,

<script language="javascript"
type="text/javascript">document.write("<?php the_time('F jS, Y')
?>");</script>

Google does not use javascript when pulling data for the description. So it will display for the user but not read by Google.

I could do these in the free themes but am unable to find the required function. I am not sure what to replace with what.

In my files, I can only see,

C:\wamp\www\wp-content\themes\TheDefensionem\cover.php:
   52  // Day
   53  if( is_day() ){
   54:  $title = get_the_date();
   55   $title_above = __('Daily Archives', 'brook');
   56  }
   ..
   58  // Month
   59  if( is_month() ){
   60:  $title = get_the_date( _x( 'F Y', 'monthly archives date format', 'brook' ) );
   61   $title_above = __('Monthly Archives', 'brook');
   62  }
   ..
   64  // Year
   65  if( is_year() ){
   66:  $title = get_the_date( _x( 'Y', 'yearly archives date format', 'brook' ) );
   67   $title_above = __('Yearly Archives', 'brook');
   68  }
