(Android) Using time of the phone

Is it possible to get time of the phone to give hourly rewards? It is probably possible via c++ but is it possible to do with blueprints at the moment?

I guess some games use it and it doesn’t affect if you change the time on your phone. Is there some sort of core time or something?

Does anyone know?

I do not know but I think a good way to do it would be to fetch the time from an i ternet server that the player doesnt own or control, and maybe even store their rewards progress in a secure database on that server. Then nothing they do to their phone will allow cheating because the server knows the truth.
