Arduino code to run a motor every 6 hours

Getting Started
1 
const int pwm = 2 ;	//initializing pin 2 as pwm
const int in_1 = 8 ;
const int in_2 = 9 ;

//For providing logic to L298 IC to choose the direction of the DC motor 

void setup()
{
pinMode(pwm,OUTPUT) ;  	//we have to set PWM pin as output
pinMode(in_1,OUTPUT) ; 	//Logic pins are also set as output
pinMode(in_2,OUTPUT) ;
}

void loop()
{
//For Clock wise motion , in_1 = High , in_2 = Low

digitalWrite(in_1,HIGH) ;
digitalWrite(in_2,LOW) ;
analogWrite(pwm,255) ;

/*setting pwm of the motor to 255
we can change the speed of rotaion
by chaning pwm input but we are only
using arduino so we are using higest
value to driver the motor  */

//Clockwise for 3 secs
delay(3000) ; 		

//For brake
digitalWrite(in_1,HIGH) ;
digitalWrite(in_2,HIGH) ;
delay(1000) ;

//For Anti Clock-wise motion - IN_1 = LOW , IN_2 = HIGH
digitalWrite(in_1,LOW) ;
digitalWrite(in_2,HIGH) ;
delay(3000) ;

//For brake
digitalWrite(in_1,HIGH) ;
digitalWrite(in_2,HIGH) ;
delay(2160000000000000) ;
 }

Will this program work correctly?? I need suggestions to make it work properly

You are aware that this is not an Arduino forum, right?

But for the question: That delay looks a bit too long for 6 hours (66060*1000 hasn’t got that many zeros).

And there are better ways that keep the rest of your code running while you are waiting for the time to pass.
