title: Is there a way to get the current time in nginx?
body: <p>I am trying to inject the time of an nginx server into an HTTP header.</p>
  
  <p>I am able to add to an HTTP header, like so:</p>
  
  <pre><code>proxy_set_header HELLO-WORLD 'something';
  </code></pre>
  
  <p>But now, I want to be able to inject the time into an HTTP header, something that looks like this:</p>
  
  <pre><code>proxy_set_header THE-TIME $time_var;
  </code></pre>
  
  <p>Or something like that.</p>
  
  <p>Would that be possible?</p>
