Type Alias TtTime 

pub type TtTime = TimePoint<Tt>;

Aliased Type

pub struct TtTime { /* private fields */ }

Implementations

impl TtTime

pub fn approximate_tdb(self) -> TdbTime

Approximates Barycentric Dynamical Time (BDT) from TT using a simplified expression following the IAU SOFA estimate TDB = TT + 0.001657 * sin(g) where g is an estimate of the Earth’s mean anomaly. The resulting estimate is accurate to 50 microseconds from 1980 to 2100.

See “SOFA Time Scale and Calendar Tools”, 2023 May 31, version for the C programming language. Section 4.3.4 “TDB minus TT”.

Trait Implementations

impl FromTimeScale<Tcg> for TtTime

fn from_time_scale(time_point: TimePoint<Tcg>) -> Self

Constructs a time point from an instant expressed in another scale.
