Struct UtcInstant 

pub struct UtcInstant { /* private fields */ }

A UTC instant, as microseconds since 1970-01-01T00:00:00Z.

Implementations

impl UtcInstant

pub const J2000: UtcInstant

2000-01-01T12:00:00Z.

pub fn from_micros(micros: i64) -> Self

From microseconds since the Unix epoch.

pub fn micros(&self) -> i64

Microseconds since the Unix epoch.

pub fn from_civil( year: i32, month: u32, day: u32, hour: u32, minute: u32, second: u32, microsecond: u32, ) -> Self

From proleptic-Gregorian calendar fields (UTC).

pub fn civil(&self) -> (i32, u32, u32, u32, u32, u32, u32)

(year, month, day, hour, minute, second, microsecond)

pub fn weekday(&self) -> u32

Python datetime.weekday(): Monday is 0.

pub fn julian_day(&self) -> f64

Julian day as the reference computes it from calendar fields.

pub fn seconds_since(&self, other: &UtcInstant) -> f64

Seconds from other to self, like Python (self - other).total_seconds().

pub fn add_micros(&self, micros: i64) -> Self

micros microseconds later (earlier if negative).

pub fn plus_days(&self, days: f64) -> Self

self + timedelta(days=days), with CPython’s rounding of float days to microseconds (whole days exact, fraction rounded half to even).

pub fn with_time( &self, hour: u32, minute: u32, second: u32, microsecond: u32, ) -> Self

Same day at another time of day (Python dt.replace(hour=…, minute=…)).

pub fn isoformat(&self) -> String

Python datetime.isoformat() of an aware UTC datetime.

pub fn parse(text: &str) -> Result<Self, ParseError>

Parse YYYY-MM-DDTHH:MM[:SS[.ffffff]] with an optional Z or +00:00 suffix.
