Formatting Exception when using DateTime for PlayerPrefs

Question

Hi i need help, i am getting a FormatException when i try the below codes, it will save datetime and save to playerprefs then on resume will get the difference from the old time and current time, but i am having an Format exception, anyone who knows how to convert these t$$anonymous$$ngs without errors? thank you

import UnityEngine; import System.Collections; import System;

var currentDate : DateTime; var oldDate : DateTime; var timex : double;

function Start() {

  //Store the current time when it starts
  currentDate = System.DateTime.Now;


 //Grab the old time from the playerprefs as a long
 var temp : long = Convert.ToInt64(PlayerPrefs.GetString("Time_Data"));


 //Convert the old time from binary to a DataTime variable
 var oldDate : DateTime = DateTime.FromBinary(temp);
 print("oldDate: " + oldDate);


 //Use the Subtract method and store the result as a timespan variable
 var difference : TimeSpan = currentDate.Subtract(oldDate);
 print("Difference: " + difference.TotalSeconds);


 timex = timex + difference.TotalSeconds;

}

function OnApplicationQuit()

{

 //Save the current system time as a string in the playerprefs class
 PlayerPrefs.SetString("Time_Data", System.DateTime.Now.ToBinary().ToString());

 print("Saving t$$anonymous$$s date to prefs: " + System.DateTime.Now);

}

@andyblueAMS001 A w$$anonymous$$le ago i was testing with somet$$anonymous$$ng like t$$anonymous$$s so I am copy pasting t$$anonymous$$s code as it is. SO you may understand it more precisely.

using System.Collections; using System.Collections.Generic; using UnityEngine; using System;

public class TimeTest : MonoBehaviour { string a; DateTime da,da1; int hours, min, sec; int hoursNow, minNow, secNow; long secondsBefore, secondsNow,timePassed; int temp;

 void Start()
 {
     temp = PlayerPrefs.GetInt("rated");
     Debug.Log("rated" + temp);
     //Debug.Log(" Time: "+System.DateTime.Now.ToString("HH:mm:ss"));
     da = System.DateTime.Now;
     PlayerPrefs.SetInt("Hours", int.Parse(da.ToString("HH")));
     PlayerPrefs.SetInt("Minutes", int.Parse(da.ToString("mm")));
     PlayerPrefs.SetInt("Seconds", int.Parse(da.ToString("ss")));

     hours=PlayerPrefs.GetInt("Hours");
     min=PlayerPrefs.GetInt("Minutes");
     sec=PlayerPrefs.GetInt("Seconds");

     //Debug.Log(" time " + hours+" "+ min+" " + sec);

     StartCoroutine(ChangeTime());
 }

 IEnumerator ChangeTime()
 {
     yield return new WaitForSeconds(10.0f);
     hours = PlayerPrefs.GetInt("Hours");
     min = PlayerPrefs.GetInt("Minutes");
     sec = PlayerPrefs.GetInt("Seconds");
     da1 = System.DateTime.Now;
     secondsBefore = (hours * 60 * 60) + (min * 60) + sec;
     hoursNow = int.Parse(da1.ToString("HH"));
     minNow= int.Parse(da1.ToString("mm"));
     secNow= int.Parse(da1.ToString("ss"));

     secondsNow= (hoursNow * 60 * 60) + (minNow * 60) + secNow;

     timePassed = secondsNow - secondsBefore;
     Debug.Log("Ti9mePassed " + timePassed);


 }
