there was an announcement on hashtalk re: payout times being moved back to normal business hours instead of the middle of the night. they should come in between 7aCST and 9aCST starting today (8/29/2014)
i had the same question/problem and called to inquire about it....
Problem is they're not making up for the lost 9-hours of mining -- costs didn't increase, and payouts didn't increase for the missing 9-hours.
Now, my account balance hasn't increased even though the system claimed it payed out -- under the new time scheme.
