Hey guys, I must say I either need EXACTLY the same feature requested in this post!
Nothing special but just an option to edit the date/clock setting it backwards while the app is running.
Going backwards all apps usually crash whenever you try to execute some actions, except one: purchasing in-game goods/items from in-app stores!
And well, I'd need the same feature purposed in this post, to purchase game items very rare which were available only during past events (like Halloween etc.)
I know for sure that it would work without game crashing, so please let me know how may I eventually use GG to set time clock backwards through the >> function...
