Functions
constexpr auto	astro::solar_time::detail::sun_mean_longitude (const double jde_tt) -> toolbox::AngleDeg
	Computes the Sun's mean longitude L0, referred to the mean equinox of the date.
auto	astro::solar_time::equation_of_time (const double jde_tt) -> toolbox::AngleDeg
	Computes the equation of time E = apparent solar time − mean solar time.
auto	astro::solar_time::apparent (const calendar::Datetime &utc_dt, const toolbox::AngleDeg &longitude) -> calendar::Datetime
	Converts a civil UTC moment to local apparent (true) solar time (真太阳时).

Variables
constexpr double	astro::solar_time::SECONDS_OF_TIME_PER_DEGREE
	Seconds of clock time per degree of hour angle.
