body: <p>What are the sqlite equivalents of <code>INTERVAL</code> and <code>UTC_TIMESTAMP</code>? For example, imagine you were "porting" the following SQL from MySQL to sqlite:</p>
  
  <pre><code>SELECT mumble
    FROM blah
   WHERE blah.heart_beat_time &gt; utc_timestamp() - INTERVAL 600 SECOND;
  </code></pre>
