Zone

Struct Zone 

Source
pub struct Zone(/* private fields */);
Expand description

A time zone: UTC, a fixed offset or an IANA zone (with its daylight saving rules). Made by parsing ("Asia/Jakarta".parse::<Zone>(), "+07:00".parse()), or Zone::UTC and Zone::fixed.

Implementations§

Source§

impl Zone

Source

pub const UTC: Zone

Coordinated Universal Time.

Source

pub const fn fixed(seconds: i32) -> Zone

A fixed offset from UTC, in seconds east (Zone::fixed(7 * 3600) is +07:00), with no daylight saving time.

Source

pub fn offset_at(&self, unix: i64) -> i64

The offset from UTC at the moment unix (seconds), in seconds.

Source

pub fn local(&self, unix: i64) -> NaiveDateTime

The wall-clock time at the moment unix.

Source

pub fn resolve(&self, local: NaiveDateTime) -> Option<i64>

The moment a wall-clock time happens. In the hour clocks skip in spring it doesn’t (None); in the hour repeated in autumn it’s the first one.

Source

pub fn fixed_at(&self, unix: i64) -> FixedOffset

The fixed offset in effect at unix, for chrono’s formatting.
