You can either use Firebase Cloud Function or write your own node.js program in a server. Here are some links which will get you started.Cloud function(https://firebase.google.com/docs/functions/get-started) or Nodejs (https://firebase.google.com/docs/admin/setup) – Praveen Kumar A X Apr 20 '18 at 04:59

Simplest approach: Write a function in a setInterval and do a check every min, to see if your start_time and server time matches. – Praveen Kumar A X Apr 20 '18 at 05:02
