When you play a social game or management game, you start to build something and turn off the game. After many hours you turn on the game and find the building is completed. How can I make this in C2, checking passed real world time including when the game is off? Maybe it will need server connection, but app like Tiny Tower doesn't need it. I'm gonna make native mobile game with CocoonJS. Is there any plugin or expressions that checking device's clock?
