Cloud Functions for Firebase trigger on time?

Question

I am looking for a way to schedule Cloud Functions for Firebase or in other words trigger them on a specific time.

What you can do, is spin up an AppEngine instance that is triggered by cron job and emits to PubSub. I wrote a blog post specifically on that, you might want to take a look:
