title: How to get milliseconds delta in Python?
body: <p>I want to get the time delta between two timestamps: <code>time1</code> and <code>time2</code>, and the result should be shown in millseconds. For example:</p>
  
  <pre><code>time1=17:00:00:121
  time2=17:01:00:121
  </code></pre>
  
  <p>the result will be 60*1000=60000.</p>
  
  <p>I can't find such a method in python (mostly shown in seconds), and <code>datetime.timedelta.total_seconds()</code> only returns seconds without the minus of minutes, hours and days.</p>
  
  <p>So anyone can tell me how to make it, thanks!</p>
