I want to integrate a secure check for a game which should check the actual time online. For example:
A player can get a gift inside the game each day. To avoid players jumping days on their device by changing the date I want to cross check the actual date online.
Now I wonder if there is some secure best practice how this can be done?
This also is interesting for games where players can "jump" forward for some hours to collect bonuses inside the game and then the game has to catch up with the "jump" time. All this kind of features require a secure online check for the actual time and I wonder how this can be done?
