The time zone.

The methods here are the primarily constructors for Date and DateTime types.

Associated Types

`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

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

Reconstructs the time zone from the offset.

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

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

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

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

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

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

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

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

Provided methods

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

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.
