Heroku: Run a function in a certain time

I'm writing a backend for a mobile application using Heroku as my deployment solution and Node.js for my platform.

What I simply try to do is to run my function clearTableX() to perform at a certain time (lets say 12PM). What function does is that it removes the elements in an entire table.

How would I be able to accomplish that? The one thing that is really important it has to run one time and one time only so that it wouldn't delete the same table over and over.

The Heroku Scheduler addon sounds like it will do what you need.
