title: Python - Timestamp Conversion
body: <p>I have converted some sensor data into <code>CSV</code> format. The data contains a <code>timestamp</code> attribute that is divided into two parts as follows:</p>
  
  <pre><code>measurement_timestamp_begin: 
    seconds: 3733032665
    fractions: 3056174174
  </code></pre>
  
  <p>I need to convert this into standard UNIX timestamp format. I saw several posts for doing the conversion but each method receives a single argument. I don't understand the <strong>fraction</strong> part.  Does it mean <strong>seconds.fraction</strong>? e.g. <strong>3733032665.3056174174</strong>.</p>
