Yes it is Possible.
When a User Clicks on a Button Store the Date and Time of Click in Firebase in MM/dd/yyyy HH:mm:ss format.
Then Call Firebase to Get Tag with Date and Time Value.
And when Firebase Got Value do -
It will work but you can wait for others to answer, they can provide you a shorter or a much efficient method.

Can you use tinyDB. When button.click compare get tinyDB data(saved time) greater than current time, call show ads and save current time to tinyDB.
Well, you can work efficiently by using Tiny DB and comparing the present system time. 
Earlier i also used TinyDB but in several Community Posts i read that its Better and Safe to Store Values in Firebase.
But why to call Data from Firebase if you can do it offline.

So it can’t be Altered Easily by Clearing App Data.
That’s another case. If you want users to login in your app, then its fine. Otherwise, Tiny DB is recommended.

i have error , to make instant
It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.
To get an image of your blocks, right click in the Blocks Editor and select “Download Blocks as Image”. You might want to use an image editor to crop etc. if required. Then post it here in the community.

So, @ninowebs Follow @golumaths100 Suggestion, If you have No Issue with User Altering the Time.

And Make Instant Only Accepts Arguments Of These 3 Format -
Again Only These Formats Are Accepted For Instant -
And What You Are Using Is
