Hi i am making a racing type game and i would like to know how to make a timer that starts when the car starts moving is that possible and if so how would i do it.

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

public class Car : MonoBehaviour {
private Rigidbody carRigid;
public int speed;
public int rotatespeed;

// Use this for initialization
void Start () {

	carRigid = GetComponent<Rigidbody> ();
}

// Update is called once per frame
void Update () {

	
}

void FixedUpdate (){

	if (Input.GetButton ("Drive")) {
		carRigid.AddForce (transform.forward * speed * Time.deltaTime);
	}

	if (Input.GetButton ("Reverse")) {
		carRigid.AddForce (transform.forward * -speed * Time.deltaTime);
	}

	if (Input.GetButton ("Left")) {
		transform.Rotate (0, -rotatespeed, 0);
	}

	if (Input.GetButton ("Right")) {
		transform.Rotate (0, rotatespeed, 0);
	}
}

}

First you have to check, when the car starts moving: if(carRigid.velocity > 0)
This some code of a timer, i once made, perhaps it will help you:

    public long hour;
    private long minute, second, milliseconds;

    public float speed = 1;

    void Update ()
    {
        milliseconds += (long)(Time.deltaTime * 1000 * speed);
        if (milliseconds >= 1000)
        {
            second += milliseconds / 1000;
            milliseconds %= 1000;

            if (second >= 60)
            {
                minute += second / 60;
                second %= 60;

                if (minute >= 60)
                {
                    hour += minute / 60;
                    minute %= 60;

                    if (hour >= 24)
                    {
                        hour %= 24;
                    }
                }
            }
        }
    }
