@Injectable()
export class AuthService {

   private cookieExpireTime: Date;

   constructor(private cookieService: CookieService) {
   }

   // Set time expired
   setCookieExpireTime() {
       let expireTime = 'your_time';
       this.cookieExpireTime = new Date(expireTime * 1000);
   }

   // Get time expired 
   getCookieExpireTime(): Date {
       return this.cookieExpireTime;
   }

   // Delete
   deleteTimeExpired(){
      this.cookieService.delete('expiredtime');
   }

   // Set time expired for token
   setTokenCookie(data: any) {
       this.cookieService.set('token_store', JSON.stringify(data), this.getCookieExpireTime());
   }

}
