The two pointer clocks of A and B are inaccurate. Clock A runs 30 seconds faster than the standard time every 24 hours, and clock B runs 120 seconds slower than the standard time every 24 hours. Suppose it is eight o'clock in the morning today. The second clock is aligned with the standard time, so that the two clocks go on continuously, so how many days will it be before the next time the two clocks both point to the same time at eight o'clock?
甲、乙两个指针式时钟都不准确，甲钟每走24小时恰好比标准时间快30秒，乙钟每走24小时恰好比标准时间慢120秒，假定今天上午八点整，把甲、乙钟都与标准时间对好，让两钟不停的走下去，那么下一次两钟都同样指在八点时，要隔多少天？
