title: AWS SDK Error - Signature not yet current
body: <p>I'm using the <code>aws-sdk-php</code>, the SesClient specifically, i've deployed an app in a customer server (hosted in DreamHost) and I'm getting this error:</p>
  
  <pre><code>Signature not yet current: 20130909T170846Z is still later than 20130909T170823Z (20130909T170323Z + 5 min.)
  </code></pre>
  
  <p>I'm guessing the server time is misconfigured, I'm trying to reach DH support to check on that, i bet that will take a while.</p>
  
  <p>Any other ideas? The app has been deployed many times before and i've never seen this error.</p>
