Golang Random number generator

Random number generator is my favorite part of all kinds of languages. Here is a piece of code which can support generating random number uniformly from 0 to 1. It is using time as seed, with the changing of time, the output will be different.

package main
import (
 "fmt"
 "math/rand"
 "time"
)
func main() {
 randNumGen := rand.New(rand.NewSource(time.Now().UnixNano()))
 i := 0
 for {
  i += 1
  time.Sleep(2 * time.Second)
  //fmt.Println(time.Now().UnixNano())
  randNumGen = rand.New(rand.NewSource(time.Now().UnixNano()))
  fmt.Println(randNumGen.Float64())
  if i > 10 {
   break
  }
 }
}
