I want to use Firebase to get the current time on server without writing to the database and then reading it.

Any one knows a solution to directly get a current time stamp from Firebase?

Yes there is! It doesn't matter if it is for IOS or for Android, you can write a frunction in Cloud Functions for Firebase which will be as easy as:

exports.currentTime = functions.https.onRequest((req, res) => 
 res.send("timestamp":new Date().getTime())
)

You can host this in Cloud Function and get the server timestamp without user interaction.

For more informations on how to set/read a timestamp in a Firebase Real-time database, please see my answer from this post.
