title: String representation of time_t?
body: <pre><code>time_t seconds;
  time(&amp;seconds);
  
  cout &lt;&lt; seconds &lt;&lt; endl;
  </code></pre>
  
  <p>This gives me a timestamp.  How can I get that epoch date into a string?</p>
  
  <pre><code>std::string s = seconds;
  </code></pre>
  
  <p>does not work</p>
