◆ getLocalTime()

struct tm dpyTime::getLocalTime ( )

std::string dpyTime::getLocalTimeStamp ( )

Format : ISO String

bool dpyTime::getSunriseSunsetLocal	(	const std::tm &	localDate,
		double	latitudeDeg,
		double	longitudeDeg,
		SunTimes::ZenithPreset	preset,
		std::time_t &	sunriseLocal,
		std::time_t &	sunsetLocal
	)

Uses std::tm date fields (tm_mday, tm_mon, tm_year).

Returns: true if sunrise/sunset could be represented for that date, false on computation errors.

bool dpyTime::getSunriseSunsetLocal	(	std::time_t	nowLocal,
		double	latitudeDeg,
		double	longitudeDeg,
		SunTimes::ZenithPreset	preset,
		std::time_t &	sunriseLocal,
		std::time_t &	sunsetLocal
	)

Unlike the calendar-date overload, this returns the daylight interval that contains nowLocal when one exists across a midnight boundary.

Returns: true if sunrise/sunset could be represented for that instant/location, false on computation errors.
