title: Is there a way to touch() a file in Amazon S3?
body: <p>I'm currently working with <a href="http://aws.amazon.com/s3/" rel="nofollow noreferrer">Amazon S3</a> and I am writing a program that uses the modified dates. I'm looking for a way to edit the modified dates.</p>
  <p>I could loop trough all the files and save them as they are, but this sounds like a bad solution.</p>
  <p>In PHP there is this function <a href="http://php.net/manual/en/function.touch.php" rel="nofollow noreferrer">touch()</a>.</p>
  <p>Does anyone know a solution, or has the same problem?</p>
