How to pause stopwatch when player enters game over scene?

Hi I'm making a 2D platformer and I want to stop a stopwatch and still display the stopped time when the player loads into the scene "game over". The stopwatch is a text on a canvas that has minutes:seconds:milliseconds. The canvas is originally from my first level and isn't destroyed on load when it passes on to the next scene.

This is the script for the timer that I have attached to the timerText using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI; using UnityEngine.SceneManagement;

public class Timer : MonoBehaviour {

 public Text timerText;
 public float minutes = 0;
 public float seconds = 0;
 public float miliseconds = 0;
 public bool isGameOver = false;
 // Use this for initialization
 void Start()
 {

 }

 // Update is called once per frame
 void Update()
 {
     UpdateTimerUI();
 }


 //call this on update
 public void UpdateTimerUI()
 {
     miliseconds+=Time.deltaTime * 1000;
     if (miliseconds >= 1000)
     {
         seconds++;
         miliseconds = 0;
     }
     else if (seconds >= 60)
     {
         minutes++;
         seconds = 0;
     }


     //Debug.Log(string.Format("{0}:{1}:{2}", minutes, seconds, (int)miliseconds));
     timerText.text = string.Format("{0}:{1}:{2}", minutes, seconds, (int)miliseconds);
 }

 ////pause timer when player enters game over scene
 //public void PauseTimer()
 //{
 //    miliseconds = 0;
 //}

}

And this is the script attached to a portal that connects the final level to the game over scene using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.SceneManagement; public class GameOver : MonoBehaviour {

 void OnTriggerEnter2D(Collider2D other)
 {
     if (other.name == "Player")
     {
         SceneManager.LoadScene("GameOver");
         Timer t = new Timer();
         t.miliseconds = 0;
     }
 }

}

Any help here would be greatly appreciated!
