I have read a lot algorithms about random-generation,most of them use the system time as the seed,and then calculate it with
formula Rand_Number = (Rand_Seed * X + Y) mod Z, why use the system time as the seed,is it random enough? then if the seed is random,why calculate it again through this formula?
