Struct Tt 

pub struct Tt;

Terrestrial Time (TT)

This is a continuous time standard for the surface of the Earth (Earth’s geoid) See Wikipedia

This type is proleptic. TT was defined in 1976, and changed in 2000 very slightly. All dates before this extrapolate backwards.

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 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 Standard for Tt

fn abbrev() -> &'static str

Short capital-letter abbreviation for the time standard (usually 2 or 3 letters)

fn tt_offset() -> Duration

Offset from Tt (This + offset = TT)

fn tt_scale() -> Option<f64>

Linear scale factor from TT, usually None
