title: Is strftime with nanoseconds possible in bash?
body: <p>Is there any way to obtain Unix Time with nanoseconds with strftime in bash?</p>
  
  <p>My line for unix time :</p>
  
  <pre><code>&lt;command&gt; |  awk '{ print strftime("%s"),  $0; }'
  </code></pre>
  
  <p>I cannot use date +%N because date is only evaluated once.</p>
  
  <p>Is there any work around?</p>
