title: Is it possible to find the time of the last message sent to an SQS queue?
body: <p>I want to know when the last message was posted to an SQS queue.</p>
  
  <p>Looking at the queue properties (via the CLI or other) I can't see anything appropriate - just the time when the queue <em>properties</em> were last modified.</p>
  
  <p>If there's a trick to finding this (without having knowledge of the clients), I'd love to know.</p>
