I use: r:=rand.New(rand.NewSource(time.Now().Unix())) r..Intn(96) I got: and val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 39 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 rand val: 82 ... mass common sequential number . But if I change that： r:=rand.New(rand.NewSource(time.Now().UnixNano())) It will not happen. Why does this happened? and how do I choose it between time.Now().Unix() or UnixNano()?
