  @thanhquan1512, generally for that a server component is used to keep track of the time.
  
  Depending on the data and the number of accesses and where the data resides, locally or on the server. However JSON can be converted to a Lua table easily and accessed, but you need to still save the data somewhere.
  
  If you make it an offline game, then you can manage it only as long as you run the app, because one can quit the app, change the time and then restart to fool the system that the time is up. You can also use a small component of your server to provide the time than the system clock which can be used to control the cheating up to a great extent.
  
  If you would save the data in a database or as data files, it can be hacked to have things that have not even been purchased. However IAP if done well (i.e. checked everytime can help prevent hacking of the same up to a large extent)
  
  The point to note is that if you want to make an offline game, then things like IAP, etc would require internet access and the moment you have that, it would make better sense to have online functionality right from the start and incorporate the points to note well in advance.
  
  These are just some of my thoughts, there could be other thoughts and ideas.

  In my opinion, user can make an IAP when using wifi. With many people a required internet connection to play game is not comfortable. And also, if I make an online game, I better implement a multiplayer game however with my ability I do not aim to make a game like that.
  
  I still consider encrypting my data when user exit game. Can anyone share experience for secure IAP data?

  If you will not use outside server for time (your server or some webservice) then your only solution seems like to track the ingame variables for abnormalities.
  Like:
  1-
  -Usually people will reverse back their time settings sooner or later. So always write the system time on some DB (Txt, sql vs..) while exiting game.
  -While opening the game check this variable with the system time again. In normal cases
  system time should be bigger than this time. (like If user is not travelling far far away to another country which has time difference )
  -Warn the user with a warning like do'not cheat bla bla ....
  
  2-You said you want to sell gold through your game. So whenever user presses that button you will already need internet connection while connecting ios or google api connect to some outsource time service and check system time from there.
  
  
  Of course these are not perfect solutions and the only real preventation method seems like checking an outside timer.
