You will want to first get all the other achievements first because changing the date and time may prevent you from some achievements syncing properly. By the way, you will still need to move fast to beat Advanced and Intermediate on lightning mode.
Choose EMP as one of the power-ups. Begin the game on the mode you want. Start by selecting any space (center works good). Use EMP as many times as the amount of tokens you have will allow. Just work your way from top left and work methodically.
Press Windows button to go back to home screen. Change the date and/or time as needed. Remember 3 minutes give you 1 token so if you need 40 tokens you will need to move ahead at least 2 hours. Go back to the game and resume. Use EMP again. Repeat until the puzzle is solved.
At the end of it all the achievement will probably not unlock for you. Do not panic. Just change the date and time back to current date and time. Beat easy/classic the regular way and now the achievement will unlock.
Enjoy the easy completion. Just make sure to change your time zone and date back to normal before unlocking any achievements.
For anyone familiar with changing the timezones for the Brothers in Arms achievement for playing on so many different days, this works the same.
