struct Foo {
date_time: UtcDateTime,
}
Retrieves a date component.
Retrieves a time component.
Unlike date
, this is not associated to the time zone.
Returns the number of non-leap seconds since January 1, 1970 0:00:00 UTC
(aka "UNIX timestamp").
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.)
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);
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
millenia, I'm curious.)
use chrono::Utc;
use chrono::TimeZone;
let dt = Utc.ymd(1970, 1, 1).and_hms_nano(0, 0, 1, 444);

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
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
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
Retrieves an associated offset from UTC.
Retrieves an associated time zone.
Changes the associated time zone.
This does not change the actual DateTime
(but will change the string representation).
Returns a view to the naive UTC datetime.
Returns a view to the naive local datetime.
Returns an RFC 2822 date and time string such as Tue, 1 Jul 2003 10:52:37 +0200
.
Returns an RFC 3339 and ISO 8601 date and time string such as 1996-12-19T16:39:57-08:00
.
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.
