title: Look for gaps in time stamps
body: <p>I have the following time stamps in a file that goes on for maybe 24 hours or slightly more:</p>
  
  <pre><code>2014-11-11-04.01.05.000000
  2014-11-11-04.03.33.000000
  2014-11-11-04.06.02.000000
  2014-11-11-04.08.31.000000 
  </code></pre>
  
  <p>The gaps between each time stamp should be less than 5 minutes.  How can I put a simple bash shell script together to parse through the file and tell me if there are gaps greater than 5 minutes?  The simplest way I see would be to subtract the next line with the previous line.  But I'm not really good with bash shell script.  Can anyone help?</p>
