I have timer and checkpoints in my game i want to write down moments when player passes this check points i can handle with text things it is easy but i cant write down time when timer still working is it possible i want to give example now time starts and you reach first checkpoint at 00:11:12 and second 00:22:44 third 00:35:32 it will be shown like this

  1. Current Time : 00:35:32 (same with
    third checpoint
    1.Check : 00:11:12
    2.Check : 00:22:44
    3.Check : 00:35:32

There is part of my timer Script corresponding i search everywhere but couldn’t find thanks a lot

	 if(SceneTestMap.GetComponent<SceneTest_Map>().checkPoint==1)
	 {
	
		checkPoint.text = TimeToString(?????);
	 }

this is the whole script

using UnityEngine;
using System.Collections;
using UnityEngine.UI;

 public class Timer : MonoBehaviour {
 
 public Text timerText;
 private float startTime;
 public GameObject SceneTestMap;
 public Text Hedef_74text;
 
     bool keepTiming;
	 float timer;
 
     void Start () {
         StartTimer();
     }
 
     void Update () {
         if(SceneTestMap.GetComponent<SceneTest_Map>().IsRaceFinished == true){
             Debug.Log("Timer stopped at " + TimeToString(StopTimer()));
         }
 
         if(keepTiming){
             UpdateTime();
         }
		 if(SceneTestMap.GetComponent<SceneTest_Map>().checkPoint==1)
		 {
		
			checkPoint.text = TimeToString(?????);
		 }
     }
 
     void UpdateTime(){
         timer = Time.time - startTime;
         timerText.text = TimeToString(timer);
     }
 
     float StopTimer(){
         keepTiming = false;
         return timer;
     }
 
     void ResumeTimer(){
         keepTiming = true;
         startTime = Time.time-timer;
     }
 
     void StartTimer(){
         keepTiming = true;
         startTime = Time.time;
     }
 
     string TimeToString(float t){
         string minutes = ((int) t / 60).ToString();
         string seconds = (t % 60 ).ToString("f2");
         return minutes + ":" + seconds;
     }
 }

How about:

text = TimeSpan.FromSeconds(timeValue).ToString();
