title: Time.now & Created_at are different? Ruby on Rails
body: <p>My site is deployed on heroku. Time.now will return today, but the created_at field of a record (created right now) will say its tomorrow. I assume this has to do with server time?</p>
  
  <p>Is there a way to make sure they're the same?
  Best,
  Elliot</p>

  <p>Update so I did this "heroku rake time:zones:us"</p>
  
  <p>it gave me:</p>
  
  <pre><code>    * UTC -10:00 *
  Hawaii
  
  * UTC -09:00 *
  Alaska
  
  * UTC -08:00 *
  Pacific Time (US &amp; Canada)
  
  * UTC -07:00 *
  Arizona
  Mountain Time (US &amp; Canada)
  
  * UTC -06:00 *
  Central Time (US &amp; Canada)
  
  * UTC -05:00 *
  Eastern Time (US &amp; Canada)
  Indiana (East)
  </code></pre>
  
  <p>however, when I set config.time_zone = 'UTC -05:00' in my environment, the app fails to start. any ideas?</p>
