Struct chrono::offset::Local

pub struct Local;

The local timescale. This is implemented via the standard time crate.

Using the TimeZone methods on the Local struct is the preferred way to construct DateTime<Local> instances.

Example

use chrono::{Local, DateTime, TimeZone};

let dt: DateTime<Local> = Local::now();
let dt: DateTime<Local> = Local.timestamp(0, 0);

Methods

impl Local

pub fn today() -> Date<Local>

Returns a Date which corresponds to the current date.

pub fn now() -> DateTime<Local>

Returns a DateTime which corresponds to the current date.

Trait Implementations

impl TimeZone for Local

type Offset = FixedOffset

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.

fn from_offset(_offset: &FixedOffset) -> Local

Reconstructs the time zone from the offset.

fn offset_from_local_date(&self, local: &NaiveDate) -> LocalResult<FixedOffset>

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

fn offset_from_local_datetime(
    &self,
    local: &NaiveDateTime
) -> LocalResult<FixedOffset>

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

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

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

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

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

fn from_local_date(&self, local: &NaiveDate) -> LocalResult<Date<Local>>

Converts the local NaiveDate to the timezone-aware Date if possible.

fn from_local_datetime(
    &self,
    local: &NaiveDateTime
) -> LocalResult<DateTime<Local>>

Converts the local NaiveDateTime to the timezone-aware DateTime if possible.

fn from_utc_date(&self, utc: &NaiveDate) -> Date<Local>

Converts the UTC NaiveDate to the local time. The UTC is continuous and thus this cannot fail (but can give the duplicate local time).

fn from_utc_datetime(&self, utc: &NaiveDateTime) -> DateTime<Local>

Converts the UTC NaiveDateTime to the local time. The UTC is continuous and thus this cannot fail (but can give the duplicate local time).

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.

fn ymd_opt(&self, year: i32, month: u32, day: u32) -> LocalResult<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.

fn yo(&self, year: i32, ordinal: u32) -> Date<Self>

Makes a new Date from year, day of year (DOY or "ordinal") and the current time zone. This assumes the proleptic Gregorian calendar, with the year 0 being 1 BCE.

fn yo_opt(&self, year: i32, ordinal: u32) -> LocalResult<Date<Self>>

Makes a new Date from year, day of year (DOY or "ordinal") and the current time zone. This assumes the proleptic Gregorian calendar, with the year 0 being 1 BCE.

fn isoywd(&self, year: i32, week: u32, weekday: Weekday) -> Date<Self>

Makes a new Date from ISO week date (year and week number), day of the week (DOW) and the current time zone. This assumes the proleptic Gregorian calendar, with the year 0 being 1 BCE. The resulting Date may have a different year from the input year.

fn isoywd_opt(
    &self,
    year: i32,
    week: u32,
    weekday: Weekday
) -> LocalResult<Date<Self>>

Makes a new Date from ISO week date (year and week number), day of the week (DOW) and the current time zone. This assumes the proleptic Gregorian calendar, with the year 0 being 1 BCE. The resulting Date may have a different year from the input year.

fn timestamp(&self, secs: i64, nsecs: u32) -> DateTime<Self>

Makes a new DateTime from the number of non-leap seconds since January 1, 1970 0:00:00 UTC (aka "UNIX timestamp") and the number of nanoseconds since the last whole non-leap second.

fn timestamp_opt(&self, secs: i64, nsecs: u32) -> LocalResult<DateTime<Self>>

Makes a new DateTime from the number of non-leap seconds since January 1, 1970 0:00:00 UTC (aka "UNIX timestamp") and the number of nanoseconds since the last whole non-leap second.

fn timestamp_millis(&self, millis: i64) -> DateTime<Self>

Makes a new DateTime from the number of non-leap milliseconds since January 1, 1970 0:00:00 UTC (aka "UNIX timestamp").

fn timestamp_millis_opt(&self, millis: i64) -> LocalResult<DateTime<Self>>

Makes a new DateTime from the number of non-leap milliseconds since January 1, 1970 0:00:00 UTC (aka "UNIX timestamp").

fn datetime_from_str(&self, s: &str, fmt: &str) -> ParseResult<DateTime<Self>>

Parses a string with the specified format string and returns a DateTime with the current offset. See the format::strftime module on the supported escape sequences.

impl Copy for Local

impl Clone for Local

fn clone(&self) -> Local

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Local

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

Formats the value using the given formatter.
