The only way to really rectify this if you don’t trust the client is to query a time service on the internet and store this information instead, without the internet connection, system time and any other mechanisms you place on the client computer can easily be manipulated.

Sorry, i dind’t understood you right.
I don’t want to make my app dependent of internet.
I know that on android is a way to make a timer that is working even app is closed. So i’m searching something like this on UE.
