    Just to let you know that I modified your function to check if the file date is within a given date interval:

    
    public function doFileDatesComparison($file) {
    	   if (is_file($file)) {
    		   $filePath = $file;
    		   if (!realpath($filePath)) {
    			   $filePath = $_SERVER["DOCUMENT_ROOT"] . $filePath;
    		   }
    		   $fileDate = filemtime($filePath);
    		   if ($fileDate) {
    			   $fileDate = date('U', $fileDate);
    
    			   if ($fileDate > $this->downBound && $fileDate upBound) {
    			   		return date('Y/m/d H:i:s', $fileDate);
    			   }
    		   }
    			return false;
    	   }
    	   return false;
    	}

      Whops my fault, I’m posting the method again after turning < into <

      
      public function doFileDatesComparison($file) {
      	   if (is_file($file)) {
      		   $filePath = $file;
      		   if (!realpath($filePath)) {
      			   $filePath = $_SERVER["DOCUMENT_ROOT"] . $filePath;
      		   }
      		   $fileDate = filemtime($filePath);
      		   if ($fileDate) {
      			   $fileDate = date('U', $fileDate);
      
      			   if ($fileDate > $this->downBound && $fileDate < $this->upBound) {
      			   		return date('Y/m/d H:i:s', $fileDate);
      			   }
      		   }
      			return false;
      	   }
      	   return false;
      	}

Posting Code

Markdown is supported in the comment area, so you can write inline code in backticks like `this` or multiline blocks of code in in triple backtick fences like ```this```. You don't need to escape code in backticks, Markdown does that for you.

Sadly, it's kind of broken. WordPress only accepts a subset of HTML in comments, which makes sense, because certainly some HTML can't be allowed, like <script> tags. But this stripping happens before the comment is processed by Markdown (via Jetpack). It seems to me that would be reversed, because after Markdown processes code in backticks, it's escaped, thus safe. If you think you can fix this issue, get in touch!

If you need to make sure the code (typically HTML) you post absolutely posts correctly, escape it and put it within <pre><code> tags.
