A Brief Intro to Zombie Farm
Zombie Farm is a portable game that is most commonly be played on the Apple iPhone, iPad, other iDevices, etc. The game is closely related to PC mainly due to it's tight integration with GameCenter and Facebook.
Games on iOS Can Sometimes be Vulnerable to a System Clock Glitch
It isn't the first game and it certainly won't be the last, using the system clock adjustment glitch [it's possible] to play the game more, at times you otherwise would not be able to play (such as while at work, while sleeping, going to school, or any other 'life' requirement that keeps us from gaming 24-7).
How to Change Your System's Time (iOS; example iPhone, iPad, other iDevice, etc.)
How to change your system's timeStep 1. Select the "System Setting" icon on your device, then, depending on the device you are using the method of changing the time may vary slightly, but you should still be able to do so using these instruction.
In 'System Settings' select 'General,' then 'Date & Time' and make your adjustment, usually forward 2, 4, 6, or 8 hours. Then restart the game. As soon as you've done whatever it is you adjusted the time for then you can change the time back to 'Set Automatically' in System Settings.
There are several reasons you may want to use this exploit in Zombie Farm, but they boil down to two key areas -- (1)Fighting, and (2)Harvesting.
Why would you want to fight earlier?
If you are adjusting your system's time so you can fight for frequently, or during times you normally would not play you'll notice the following benefits:
Make More Money Quicker!
Making money faster ultimately means making more money, and if you have money, more freely throughout the game, it can have a very positive effect on the game experience. So how do you do this? It's simple. Just before you reach a time when you cannot play the game, whip out your iPhone or iPad and adjust the time forward a bit, so you don't lose those gaming sessions because of something as silly as work, school, or studying.
Get a Free Boost!
The boosts you win during battle are kept, meaning the game mechanic for tallying and storing the boosts are intact. This is a good thing, it means if you win a brain, well, you keep it.
The boosts you can win are InstaPolw, InstaHarvest, InstaHunger, and InstaGrow. It may be possible to get ReGrowth, although I never have.
Keep in mind that these are items that normally would require purchase with the use of a Brain, you cannot use Gold to purchase these items.
Another chance for a FREE BRAIN!
Everytime you fight there is a chance of winning a Brain, this is in addition to whatever the loot is, you always have the chance to win a brain during a fight.
Why would you want to harvest earlier?
I understand that simply stating this question, almost automatically answers it, so bear with me as we trudge on through what should already be quite clear.
Make more money by harvesting more often!
Using this time exploit so that you can harvest more often, and at times when you normally could not play (bad place, time, whatever), by doing so you will harvest more often, which equates to more Gold.
Increase your number of Zombies quickly!
This is often needed during the very early levels or levels in which you are transitioning to a higher level opponent and don't have the battle tactic worked out yet.

Bonus Tip #1
This is bonus tip #1 from Zombie Expert Christina:
"Before you head to the App Store to look for newly released apps, go to the market within the game. There are some free apps and other that, if purchased via in-app, they can reward you with brain fragment (used to create brains). At least this way you know if you pay for an app you get something for it. Trust me, I've been through more lousy apps than I've seen excellent ones."
