title: How do I check the expiration date on a memcached entry
body: <p>I'm running apache/php/memcached on ubuntu 12.04</p>
  
  <p>The keys I am setting are persisting beyond their expiration.  We are using the same code that worked with the memcached PAAS we are migrating from.</p>
  
  <p>How do I confirm that the expiration is actually being set on a key?</p>
  
  <p>If I telnet and get [mykey] it simply shows the value, not the expiration.</p>
