Struct chrono::naive::TsSeconds

pub struct TsSeconds(_);

A DateTime that can be deserialized from a seconds-based timestamp

Methods from Deref<Target = NaiveDateTime>

pub fn date(&self) -> NaiveDate

Retrieves a date component.

Example

use chrono::NaiveDate;

let dt = NaiveDate::from_ymd(2016, 7, 8).and_hms(9, 10, 11);
assert_eq!(dt.date(), NaiveDate::from_ymd(2016, 7, 8));

pub fn time(&self) -> NaiveTime

Retrieves a time component.

Example

use chrono::{NaiveDate, NaiveTime};

let dt = NaiveDate::from_ymd(2016, 7, 8).and_hms(9, 10, 11);
assert_eq!(dt.time(), NaiveTime::from_hms(9, 10, 11));

pub fn timestamp(&self) -> i64

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.

Example

use chrono::NaiveDate;

let dt = NaiveDate::from_ymd(1970, 1, 1).and_hms_milli(0, 0, 1, 980);
assert_eq!(dt.timestamp(), 1);

let dt = NaiveDate::from_ymd(2001, 9, 9).and_hms(1, 46, 40);
assert_eq!(dt.timestamp(), 1_000_000_000);

pub fn timestamp_subsec_millis(&self) -> u32

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.

Example

use chrono::NaiveDate;

let dt = NaiveDate::from_ymd(2016, 7, 8).and_hms_nano(9, 10, 11, 123_456_789);
assert_eq!(dt.timestamp_subsec_millis(), 123);

let dt = NaiveDate::from_ymd(2015, 7, 1).and_hms_nano(8, 59, 59, 1_234_567_890);
assert_eq!(dt.timestamp_subsec_millis(), 1_234);

pub fn timestamp_subsec_micros(&self) -> u32

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.

Example

use chrono::NaiveDate;

let dt = NaiveDate::from_ymd(2016, 7, 8).and_hms_nano(9, 10, 11, 123_456_789);
assert_eq!(dt.timestamp_subsec_micros(), 123_456);

let dt = NaiveDate::from_ymd(2015, 7, 1).and_hms_nano(8, 59, 59, 1_234_567_890);
assert_eq!(dt.timestamp_subsec_micros(), 1_234_567);

pub fn timestamp_subsec_nanos(&self) -> u32

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.

Example

use chrono::NaiveDate;

let dt = NaiveDate::from_ymd(2016, 7, 8).and_hms_nano(9, 10, 11, 123_456_789);
assert_eq!(dt.timestamp_subsec_nanos(), 123_456_789);

let dt = NaiveDate::from_ymd(2015, 7, 1).and_hms_nano(8, 59, 59, 1_234_567_890);
assert_eq!(dt.timestamp_subsec_nanos(), 1_234_567_890);

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

Formats the combined date and time with the specified formatting items. Otherwise it is same to the ordinary format method.

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

Example

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

let fmt = StrftimeItems::new("%Y-%m-%d %H:%M:%S");
let dt = NaiveDate::from_ymd(2015, 9, 5).and_hms(23, 56, 4);
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");

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(2015, 9, 5).and_hms(23, 56, 4);
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");
