ojx111: 确实有问题. I have the same problem. It looks like you have to do it before midnight (beijing time) to count. But, if I do in the evening(CST), it said 'you already did it'. Once, I did it right after midnight (Beijing time), the system regards it as a new count (3 金币). It looks like it only have 12 hours frame (USA midnight to noon). (12-4 03:31)
