실습 CODE

void main() {
  
  // 날짜
  DateTime now = DateTime.now();
  
  print(now);
  print(now.year);
  print(now.month);
  print(now.day);
  print(now.second);
  print(now.millisecond);
  
  // 기간
  Duration duration = Duration(seconds: 60);
  
  print(duration);
  print(duration.inDays);
  print(duration.inHours);
  print(duration.inMinutes);
  print(duration.inMilliseconds);
  
  DateTime specificDay = DateTime(
    2017,
    11,
    23,
  );
  
  print(specificDay);
  
  final diff = now.difference(specificDay);
  
  print(diff);
  print(diff.inDays);
  print(diff.inHours);
  print(diff.inMinutes);
  
  print(now.isAfter(specificDay));
  print(now.isBefore(specificDay));
  
  print('---------------------------');
  print(now);
  print(now.add(Duration(hours: 10)));
  print(now.subtract(Duration(seconds: 20)));
  
}
