title: Schedule task for every 4 hours in Node.js
body: <p>How could I schedule a task to run after 4 hours using "node-schedule" in Node.js
  Currently my code is as below but it isn't responding as expected.</p>
  
  <pre><code>var schedule = require('node-schedule');
  var task = schedule.scheduleJob('* */4 * * *', function () {
      console.log('Scheduled Task');
  });
  </code></pre>
