title: Node.js Run service only at a suitable time
body: <p>I made a service in Node.js which runs fine. But I've decided to make a change. Untill the time isn't between lets say 7pm and 5am, don't run the service - be in standby mode - or sleep. </p>
  
  <p>Which command or method to use? Is there something specific for such cases?</p>
