Manual Steps:In Zombie farm, you can speed up the clock by using the speed settings in CIH2. I haven't tried changing the time on my phone yet. The only drawback that I see, is that even though the time adjusts to when you can invade, the next time you log back into the game, it resets the time for invade back to what it should be. To include all the times you invaded during the hack. This helps out with growing of crops big time though.
