title: How do I start chronometer with a specific starting time?
body: <p>Let's say I have this variable:</p>
  
  <pre><code>long myMillis = 20000;
  </code></pre>
  
  <p>This means that I want my Chronometer to start at exactly 20 seconds (00:20).</p>
  
  <p>I tried doing this:</p>
  
  <pre><code>chronometer.setBase(myMillis);
  </code></pre>
  
  <p>But it doesn't work. It dosn't start with 20 seconds. It starts with some weird time that doesn't make sense.</p>
