title: Ahoy_email gem : clicked_at, opened_at not getting updated?
body: <p>I'm using <a href="https://github.com/ankane/ahoy_email" rel="nofollow">ahoy_email</a> ruby gem to track the emails I send. It should give me the time at when it is opened and clicked. But it's not working properly to give the time. What I'm missing.</p>
  
  <p>Note: I run the project in my localhost</p>
