Unity 5 - Time counter Up script (millisecond precision) UI

Hey,
Just wondering how do you create a script that constantly counts up in game, with Millisecond precision.

The timer must be able to continue after the scene is reloaded, or another scene with the timer.
Example:
“01:34:87”

Thanks.

public class timer : MonoBehaviour
{

 public Text timerLabel;
 
 public float time;


 
 void Update() {

     
     time += Time.deltaTime;
     
     var minutes = Mathf.Floor(time / 60); //Divide the guiTime by sixty to get the minutes.
     var seconds = time % 60;//Use the euclidean division for the seconds.
     var fraction = (time * 100) % 100;
     
     //update the label value
     timerLabel.text = string.Format ("{0:00} : {1:00} : {2:00}", minutes, seconds, fraction);
 }
