I was just curious how a person would go about stopping someone from adjusting their computer clock and speeding up a game, which could be sort of cheating. Like say you had something that you needed to check the clock and compare, similar to FarmVille, Animal Crossing, etc. Is there any way to prevent that locally, if you had it be something you run on your PC, and not a website/server? It's something I've though about in the past and couldn't think of how you might go about doing that.
It's not really a big deal I suppose, if someone wants to cheat on the game then that's their business (assuming you aren't doing some multiplayer or leaderboard thing). But I'm still curious if that's possible to do. I guess you could have it check some remote clock of some sort online, but I wouldn't even begin to have a clue how you'd do that. And if they had no internet access, or that server went offline, the game would essentially be broken.
I remember reading about this iPad game, Smurf Village, which was basically a FarmVille clone, and they had to fix it because people were doing this.
