title: How to interpret memcached cachedump?
body: <p>I added an entry to memcached and looking at the cachedump.</p>
  
  <pre><code>set a 0 0 5
  hello
  STORED
  
  stats cachedump 1 5
  ITEM a [5 b; 1312548967 s]
  END
  </code></pre>
  
  <p>The first value <code>5 b</code> is size of the item which is 5 bytes. The second one is what I'm confused about. It looks like time since epoch. </p>
  
  <p>I tried adding another entry and even that entry got exactly same value.</p>
  
  <pre><code>set b 0 0 5
  hello
  STORED
  
  stats cachedump 1 5
  ITEM b [5 b; 1312548967 s]
  ITEM a [5 b; 1312548967 s]
  END
  </code></pre>
  
  <p>It looks like some kind of time, but I'm not sure what it really is. Can some one explain it?</p>
