C++ (Cpp) IsDaylightSavingの例

コード例 #1

ファイル: DateTimeAdapter.cpp プロジェクト: GuilhermeMatheus/AcessoUFABC

DateTime DateTimeAdapter::ToUTC( DateTime value ) {
	int hour = value.hour(),
		day = value.day(),
		month = value.month(),
		year = value.year(),
		dow = value.dayOfWeek() - 1;

	int daylightSavingOffset = IsDaylightSaving(day, month, year, dow) ? -1 : 0;
	int timeZoneOffset = System::DT_getTimeZoneOffset();

	int offset = timeZoneOffset + daylightSavingOffset;

	AddHours( &hour, &day, &month, &year, -offset );

	return DateTime(year, month, day, hour, value.minute(), value.second());
