pub fn date(&self) -> NaiveDate

Retrieves a date component.

§Example
use chrono::NaiveDate;

let dt = NaiveDate::from_ymd_opt(2016, 7, 8).unwrap().and_hms_opt(9, 10, 11).unwrap();
assert_eq!(dt.date(), NaiveDate::from_ymd_opt(2016, 7, 8).unwrap());
Source

pub fn time(&self) -> NaiveTime

Retrieves a time component.

§Example
use chrono::{NaiveDate, NaiveTime};

pub fn timestamp(&self) -> i64

👎Deprecated since 0.4.35: use .and_utc().timestamp() instead

Returns the number of non-leap seconds since the midnight on January 1, 1970.

Note that this does not account for the timezone! The true “UNIX timestamp” would count seconds since the midnight UTC on the epoch.

Source

pub fn timestamp_millis(&self) -> i64

👎Deprecated since 0.4.35: use .and_utc().timestamp_millis() instead

Returns the number of non-leap milliseconds since midnight on January 1, 1970.

Note that this does not account for the timezone! The true “UNIX timestamp” would count seconds since the midnight UTC on the epoch.

Source

pub fn timestamp_micros(&self) -> i64

👎Deprecated since 0.4.35: use .and_utc().timestamp_micros() instead

Returns the number of non-leap microseconds since midnight on January 1, 1970.

Note that this does not account for the timezone! The true “UNIX timestamp” would count seconds since the midnight UTC on the epoch.

Source

pub fn timestamp_nanos(&self) -> i64

👎Deprecated since 0.4.31: use .and_utc().timestamp_nanos_opt() instead

Returns the number of non-leap nanoseconds since midnight on January 1, 1970.

Note that this does not account for the timezone! The true “UNIX timestamp” would count seconds since the midnight UTC on the epoch.

§Panics

An i64 with nanosecond precision can span a range of ~584 years. This function panics on an out of range NaiveDateTime.

The dates that can be represented as nanoseconds are between 1677-09-21T00:12:43.145224192 and 2262-04-11T23:47:16.854775807.

Source

pub fn timestamp_nanos_opt(&self) -> Option<i64>

👎Deprecated since 0.4.35: use .and_utc().timestamp_nanos_opt() instead

Returns the number of non-leap nanoseconds since midnight on January 1, 1970.

Note that this does not account for the timezone! The true “UNIX timestamp” would count seconds since the midnight UTC on the epoch.

§Errors

An i64 with nanosecond precision can span a range of ~584 years. This function returns None on an out of range NaiveDateTime.

The dates that can be represented as nanoseconds are between 1677-09-21T00:12:43.145224192 and 2262-04-11T23:47:16.854775807.

Source

pub fn timestamp_subsec_millis(&self) -> u32

👎Deprecated since 0.4.35: use .and_utc().timestamp_subsec_millis() instead

Returns the number of milliseconds since the last whole non-leap second.

The return value ranges from 0 to 999, or for leap seconds, to 1,999.

Source

pub fn timestamp_subsec_micros(&self) -> u32

👎Deprecated since 0.4.35: use .and_utc().timestamp_subsec_micros() instead

Returns the number of microseconds since the last whole non-leap second.

The return value ranges from 0 to 999,999, or for leap seconds, to 1,999,999.

Source

pub fn timestamp_subsec_nanos(&self) -> u32

👎Deprecated since 0.4.36: use .and_utc().timestamp_subsec_nanos() instead

Returns the number of nanoseconds since the last whole non-leap second.

The return value ranges from 0 to 999,999,999, or for leap seconds, to 1,999,999,999.

Source

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. Otherwise it is the same as the ordinary format method.

The Iterator of items should be Cloneable, since the resulting DelayedFormat value may be formatted multiple times.

§Example
use chrono::format::strftime::StrftimeItems;
use chrono::NaiveDate;

let fmt = StrftimeItems::new("%Y-%m-%d %H:%M:%S");
let dt = NaiveDate::from_ymd_opt(2015, 9, 5).unwrap().and_hms_opt(23, 56, 4).unwrap();
assert_eq!(dt.format_with_items(fmt.clone()).to_string(), "2015-09-05 23:56:04");
assert_eq!(dt.format("%Y-%m-%d %H:%M:%S").to_string(), "2015-09-05 23:56:04");

The resulting DelayedFormat can be formatted directly via the Display trait.

assert_eq!(format!("{}", dt.format_with_items(fmt)), "2015-09-05 23:56:04");
Source

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

Formats the combined date and time with the specified format string. See the format::strftime module on the supported escape sequences.

This returns a DelayedFormat, which gets converted to a string only when actual formatting happens. You may use the to_string method to get a String, or just feed it into print! and other formatting macros. (In this way it avoids the redundant memory allocation.)

A wrong format string does not issue an error immediately. Rather, converting or formatting the DelayedFormat fails. You are recommended to immediately use DelayedFormat for this reason.

§Example
use chrono::NaiveDate;

let dt = NaiveDate::from_ymd_opt(2015, 9, 5).unwrap().and_hms_opt(23, 56, 4).unwrap();
assert_eq!(dt.format("%Y-%m-%d %H:%M:%S").to_string(), "2015-09-05 23:56:04");
assert_eq!(dt.format("around %l %p on %b %-d").to_string(), "around 11 PM on Sep 5");

The resulting DelayedFormat can be formatted directly via the Display trait.

assert_eq!(format!("{}", dt.format("%Y-%m-%d %H:%M:%S")), "2015-09-05 23:56:04");
assert_eq!(format!("{}", dt.format("around %l %p on %b %-d")), "around 11 PM on Sep 5");
Source

pub fn and_local_timezone<Tz>(&self, tz: Tz) -> LocalResult<DateTime<Tz>>
where Tz: TimeZone,

Converts the NaiveDateTime into a timezone-aware DateTime<Tz> with the provided time zone.

§Example
use chrono::{FixedOffset, NaiveDate};
let hour = 3600;
let tz = FixedOffset::east_opt(5 * hour).unwrap();
let dt = NaiveDate::from_ymd_opt(2015, 9, 5)
    .unwrap()
    .and_hms_opt(23, 56, 4)
    .unwrap()
    .and_local_timezone(tz)
    .unwrap();
assert_eq!(dt.timezone(), tz);
Source

pub fn and_utc(&self) -> DateTime<Utc>

Converts the NaiveDateTime into the timezone-aware DateTime<Utc>.

§Example
use chrono::{NaiveDate, Utc};
let dt =
    NaiveDate::from_ymd_opt(2023, 1, 30).unwrap().and_hms_opt(19, 32, 33).unwrap().and_utc();
assert_eq!(dt.timezone(), Utc);
