Struct TT 

pub struct TT { /* private fields */ }

Terrestrial Time (TT).

TT is the modern astronomical time standard for geocentric ephemerides. It provides a uniform time scale for planetary and lunar ephemeris calculations.

TT = TAI + 32.184 seconds

Implementations

impl TT

pub fn new(tt_seconds: f64) -> Self

Create a new TT time from TT seconds.

pub fn seconds(&self) -> f64

Get the TT seconds value.

pub fn add_seconds(&self, seconds: f64) -> Self

Add seconds to the TT time.

pub fn diff(&self, other: &TT) -> f64

Difference between two TT times in seconds.

pub fn to_jd(&self) -> f64

Convert to Julian Date (in TT scale).

pub fn from_jd(jd: f64) -> Self

Create from Julian Date (in TT scale).

pub fn julian_centuries_j2000(&self) -> f64

Calculate Julian centuries since J2000.0. This is commonly used for precession/nutation calculations.

Trait Implementations

impl Clone for TT

fn clone(&self) -> TT

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TT

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TT

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for TT

fn eq(&self, other: &TT) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for TT
