title: Sorting results of ps by start time
body: <p>I'm displaying information about the current processes using this variety of the <code>ps</code> command:</p>
  
  <pre><code>ps -eo pid,start,stime,command
  </code></pre>
  
  <p><strong>How can I sort these results by start?</strong></p>
  
  <p>I've read <code>man ps</code> and tried <code>-m</code>, <code>-r</code> and <code>-v</code> sorting options. Unfortunately I haven't been able to use these options to sort by start.</p>
