Fields

inner: DateTime<Local>

Implementations

impl DateTimeNative

pub fn now() -> DateTimeNative

Returns a DateTime which corresponds to the current date and time.

pub fn from_str(arg: &str) -> Result<DateTimeNative, Error>

create from str

Methods from Deref<Target = DateTime<Local>>

pub fn date(&self) -> Date<Tz>

Retrieves a date component.

pub fn time(&self) -> NaiveTime

Retrieves a time component. Unlike date, this is not associated to the time zone.

pub fn timestamp(&self) -> i64

Returns the number of non-leap seconds since January 1, 1970 0:00:00 UTC (aka “UNIX timestamp”).

pub fn timestamp_millis(&self) -> i64

Returns the number of non-leap-milliseconds since January 1, 1970 UTC

Note that this does reduce the number of years that can be represented from ~584 Billion to ~584 Million. (If this is a problem, please file an issue to let me know what domain needs millisecond precision over billions of years, I’m curious.)

Example

use chrono::Utc;
use chrono::TimeZone;

let dt = Utc.ymd(1970, 1, 1).and_hms_milli(0, 0, 1, 444);
assert_eq!(dt.timestamp_millis(), 1_444);

let dt = Utc.ymd(2001, 9, 9).and_hms_milli(1, 46, 40, 555);
assert_eq!(dt.timestamp_millis(), 1_000_000_000_555);

pub fn timestamp_nanos(&self) -> i64

Returns the number of non-leap-nanoseconds since January 1, 1970 UTC

Note that this does reduce the number of years that can be represented from ~584 Billion to ~584. (If this is a problem, please file an issue to let me know what domain needs nanosecond precision over millennia, I’m curious.)

Example

use chrono::Utc;
use chrono::TimeZone;

let dt = Utc.ymd(1970, 1, 1).and_hms_nano(0, 0, 1, 444);
assert_eq!(dt.timestamp_nanos(), 1_000_000_444);

let dt = Utc.ymd(2001, 9, 9).and_hms_nano(1, 46, 40, 555);
assert_eq!(dt.timestamp_nanos(), 1_000_000_000_000_000_555);

pub fn timestamp_subsec_millis(&self) -> u32

Returns the number of milliseconds since the last second boundary

warning: in event of a leap second, this may exceed 999

note: this is not the number of milliseconds since January 1, 1970 0:00:00 UTC

pub fn timestamp_subsec_micros(&self) -> u32

Returns the number of microseconds since the last second boundary

warning: in event of a leap second, this may exceed 999_999

note: this is not the number of microseconds since January 1, 1970 0:00:00 UTC

pub fn timestamp_subsec_nanos(&self) -> u32

Returns the number of nanoseconds since the last second boundary

warning: in event of a leap second, this may exceed 999_999_999

note: this is not the number of nanoseconds since January 1, 1970 0:00:00 UTC

pub fn offset(&self) -> &<Tz as TimeZone>::Offset

Retrieves an associated offset from UTC.

pub fn timezone(&self) -> Tz

Retrieves an associated time zone.

pub fn with_timezone<Tz2>(&self, tz: &Tz2) -> DateTime<Tz2> where
    Tz2: TimeZone, 

Changes the associated time zone. This does not change the actual DateTime (but will change the string representation).

pub fn naive_utc(&self) -> NaiveDateTime

Returns a view to the naive UTC datetime.

pub fn naive_local(&self) -> NaiveDateTime

Returns a view to the naive local datetime.

pub fn to_rfc2822(&self) -> String

Returns an RFC 2822 date and time string such as Tue, 1 Jul 2003 10:52:37 +0200.

pub fn to_rfc3339(&self) -> String

Returns an RFC 3339 and ISO 8601 date and time string such as 1996-12-19T16:39:57-08:00.

pub fn to_rfc3339_opts(&self, secform: SecondsFormat, use_z: bool) -> String

Return an RFC 3339 and ISO 8601 date and time string with subseconds formatted as per a SecondsFormat. If passed use_z true and the timezone is UTC (offset 0), use ‘Z’, as per Fixed::TimezoneOffsetColonZ. If passed use_z false, use Fixed::TimezoneOffsetColon.

Examples

let dt = Utc.ymd(2018, 1, 26).and_hms_micro(18, 30, 9, 453_829);
assert_eq!(dt.to_rfc3339_opts(SecondsFormat::Millis, false),
           "2018-01-26T18:30:09.453+00:00");
assert_eq!(dt.to_rfc3339_opts(SecondsFormat::Millis, true),
           "2018-01-26T18:30:09.453Z");
assert_eq!(dt.to_rfc3339_opts(SecondsFormat::Secs, true),
           "2018-01-26T18:30:09Z");

let pst = FixedOffset::east(8 * 60 * 60);
let dt = pst.ymd(2018, 1, 26).and_hms_micro(10, 30, 9, 453_829);
assert_eq!(dt.to_rfc3339_opts(SecondsFormat::Secs, true),
           "2018-01-26T10:30:09+08:00");

pub fn format_with_items<'a, I, B>(&self, items: I) -> DelayedFormat<I> where
    I: Iterator<Item = B> + Clone,
    B: Borrow<Item<'a>>, 

Formats the combined date and time with the specified formatting items.

pub fn format(&self, fmt: &'a str) -> DelayedFormat<StrftimeItems<'a>>
