title: Heroku: Run a function in a certain time
body: <p>I'm writing a backend for a mobile application using <b>Heroku</b> as my deployment solution and <b>Node.js</b> for my platform.</p>
  
  <p>What I simply try to do is to run my function <b>clearTableX()</b> to perform at a certain time (lets say 12PM). What function does is that it removes the elements in an entire table. </p>
  
  <p>How would I be able to accomplish that? The one thing that is really important it has to run <b>one time and one time</b> only so that it wouldn't delete the same table over and over. </p>
