Struct Utc 

pub struct Utc;

Universal Coordinated Time (UTC)

This is civil time as usually reported. It is discontinuous, having leap seconds inserted from time to time based on the Earth’s rotation.

This type is proleptic. For all dates prior to 1 Jan 1972, we presume 9 seconds have elapsed (like leaps) offsetting from TAI permanently by 9 seconds, even though that’s not what happened at the time (what happened at the time was that UTC wasn’t syncronized to TAI by integer leap seconds, but rather to other time sources and contained fractional leap seconds which are hard to reconstruct or even get a list of). For all dates prior to 1 January 1960, UTC didn’t exist, but we pretend it did, offset 9 seconds from TAI.

Trait Implementations

impl Clone for Utc

fn clone(&self) -> Utc

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Utc

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

Formats the value using the given formatter.

impl PartialEq for Utc

fn eq(&self, other: &Utc) -> 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 Utc

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
