title: check if timestamp is in certain range using bash script
body: <p>Say I have a bunch of time stamps</p>
  
  <p>As I iterate over these timestamps,</p>
  
  <pre><code>01:23:00
  12:34:14
  17:09:12
  ...
  </code></pre>
  
  <p>I want to include only timestamps  between 08:00:00 and 17:00:00</p>
  
  <p>please suggest</p>
