Rbatis DateTime
Fields
inner: NaiveDateTime
Implementations
Returns a DateTime
which corresponds to the current date and time.
Methods from Deref<Target = NaiveDateTime>
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));
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));
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);
let dt = NaiveDate::from_ymd(1969, 12, 31).and_hms(23, 59, 59);
assert_eq!(dt.timestamp(), -1);
let dt = NaiveDate::from_ymd(-1, 1, 1).and_hms(0, 0, 0);
assert_eq!(dt.timestamp(), -62198755200);
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.
Note also 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::NaiveDate;
let dt = NaiveDate::from_ymd(1970, 1, 1).and_hms_milli(0, 0, 1, 444);
assert_eq!(dt.timestamp_millis(), 1_444);
let dt = NaiveDate::from_ymd(2001, 9, 9).and_hms_milli(1, 46, 40, 555);
assert_eq!(dt.timestamp_millis(), 1_000_000_000_555);
let dt = NaiveDate::from_ymd(1969, 12, 31).and_hms_milli(23, 59, 59, 100);
assert_eq!(dt.timestamp_millis(), -900);
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
Note also that this does reduce the number of years that can be represented from ~584 Billion to ~584 years. The dates that can be represented as nanoseconds are between 1677-09-21T00:12:44.0 and 2262-04-11T23:47:16.854775804.
(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::{NaiveDate, NaiveDateTime};
let dt = NaiveDate::from_ymd(1970, 1, 1).and_hms_nano(0, 0, 1, 444);
assert_eq!(dt.timestamp_nanos(), 1_000_000_444);
let dt = NaiveDate::from_ymd(2001, 9, 9).and_hms_nano(1, 46, 40, 555);
const A_BILLION: i64 = 1_000_000_000;
let nanos = dt.timestamp_nanos();
assert_eq!(nanos, 1_000_000_000_000_000_555);
assert_eq!(
dt,
NaiveDateTime::from_timestamp(nanos / A_BILLION, (nanos % A_BILLION) as 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);
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);
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, B>(&self, items: I) -> DelayedFormat<I> where
I: Iterator<Item = B> + Clone,
B: Borrow<Item<'a>>,
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 Clone
able,
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");
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");
