Affected Resource(s)

Terraform Configuration Files

resource "random_shuffle" "mu_random_subnet" {
  input = ["a", "b", "c"]
  result_count = 1
  count = "10"
}

output "mu_shuffles" {
  value = ["${random_shuffle.mu_random_subnet.*.result}"]
}

Debug Output

Actual Behavior

This is not random for small or fast operations

Steps to Reproduce

Please list the steps required to reproduce the issue, for example:

1. terraform apply

Suggestion

I have tested using UnixNano() instead of Unix and that fixes it. I will submit a PR
