Now that you have unlocked the in-game secrets of plants versus zombies, you may want to do a little more tinkering. There is one exploit for the zen garden in plants versus zombies. It involves a setting in your can computer that can be easily changed. It is the system time.

Here is how you can cheat the zen garden so that chocolates would have an infinite duration. This will use batch commands or batch scripting.

Type the following code in notepad:

@echo on
:mark
time hh:mm:ss
goto mark

Then save it as anyfilenameyouwant.bat

Yes. It's just a four liner. Replace hh:mm:ss with the time at least one second after you have applied all chocolates, phonograph and bug sprays. The code 'hh' is for hours, 'mm' is for minutes and 'ss' is for seconds.

Double-click your computer clock to find out what is the exact time. The format is military time. There will be no AM or PM. If it is 1 in the afternoon, it is written as 13:00:00.

You have a margin of up to five minutes between the time of application of the chocolates, bug sprays, etc, and the time you will input in the script before the effects will begin to dissipate. In other words, if you applied such power ups in, let's say, 12:00:00, you need to activate the script before 12:05:00 or less before the effects of the power ups begin to wear off. It will be more efficient if the script was activated at the height of their effect.

Once you are happy with what is happening in your zen garden, run the script. It will make the time in your garden freeze. But not the coin dropping and gathering part.

DO NOT FORGET to synchronize your computer clock with another clock as this script will modify the system time. Or else, you won't be able to put back the real time.

The script will iterate creating an infinite loop of 'time' commands. It will definitely freeze your system clock to the specified time.

Once you want to end the script, press CTRL+C. It will ask if you want to terminate the batch job. Type in y for yes then hit ENTER. Re-synchronize your computer clock with the correct time afterwards.

The script will use some processor cycles. But it won't use up everything. Plants versus Zombies will still function properly. You might experience some choppiness if your computer is too old. But it won't be too much.

You can opt to hide the process 'echoing' by adding "@echo off" instead of "@echo on". But do not close the command prompt.

NOTE: Shifting or Freezing the time will have effects on the following game elements:
Duration of chocolates
Duration of "Happiness" of plants in all gardens
Crazy Dave's marigolds

Last words of advice: Try not to blow up your computer.
