Eternity warriors 2 time count runs off of the IOS date and time,
With this knowledge, just by manipulating the date can lead to some positive effects. Here are some I've found;

(1st) Double Coins

How to;
•All you have to do is go into settings and set the date of your IOS device for
"11/1/12 - 11/3/12."
Those 3 days where when the "Double Coins Event" was set to occur•
(P.s: if it doesn't work, days 1 and 3 are when it started/ended so your time may be off of the time the event was occurring. I recommend setting the date for 11/2/12 for it to work correctly)

(2nd) Daily reward
How to:
•sorta like the one above but instead of setting the date to a specific date, just increase the date by 1 day
(ex: if it is 6/3/12, you would switch it to 6/4/12)
what this does is trick the game into thinking a day has past, thus giving you the DW
