    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
    
    NSDate * senddate = [NSDate date];
    NSCalendar * cal = [NSCalendar currentCalendar];
    
    NSUInteger unitFlags = NSDayCalendarUnit | NSMonthCalendarUnit | NSYearCalendarUnit;
    NSDateComponents * component = [cal components:unitFlags fromDate:senddate];
    
    NSInteger year = [component year];
    NSInteger month = [component month];
    NSInteger day = [component day];
    
    NSLog(@"%4d/%2d/%2d",year,month,day);
