Expand description

The time zone.

The methods here are the primary constructors for the DateTime type.

Required Associated Types§

Source

type Offset: Offset

An associated offset type. This type is used to store the actual offset in date and time types. The original TimeZone value can be recovered via TimeZone::from_offset.

Required Methods§

Source

fn from_offset(offset: &Self::Offset) -> Self

Reconstructs the time zone from the offset.

Source

fn offset_from_local_date( &self, local: &NaiveDate, ) -> MappedLocalTime<Self::Offset>

Creates the offset(s) for given local NaiveDate if possible.

Source

fn offset_from_local_datetime( &self, local: &NaiveDateTime, ) -> MappedLocalTime<Self::Offset>

Creates the offset(s) for given local NaiveDateTime if possible.

Source

fn offset_from_utc_date(&self, utc: &NaiveDate) -> Self::Offset

Creates the offset for given UTC NaiveDate. This cannot fail.

Source

fn offset_from_utc_datetime(&self, utc: &NaiveDateTime) -> Self::Offset

Creates the offset for given UTC NaiveDateTime. This cannot fail.

Provided Methods§

Source

fn with_ymd_and_hms( &self, year: i32, month: u32, day: u32, hour: u32, min: u32, sec: u32, ) -> MappedLocalTime<DateTime<Self>>

Make a new DateTime from year, month, day, time components and current time zone.

This assumes the proleptic Gregorian calendar, with the year 0 being 1 BCE.

Returns MappedLocalTime::None on invalid input data.

Source

fn ymd(&self, year: i32, month: u32, day: u32) -> Date<Self>

👎Deprecated since 0.4.23: use with_ymd_and_hms() instead

Makes a new Date from year, month, day and the current time zone. This assumes the proleptic Gregorian calendar, with the year 0 being 1 BCE.
