source · [−]Expand description
Timestamp with millisecond precision.
Tuple Fields
0: DateTime<Utc>
Methods from Deref<Target = DateTime<Utc>>
sourcepub fn time(&self) -> NaiveTime
pub fn time(&self) -> NaiveTime
Retrieves a time component.
Unlike date
, this is not associated to the time zone.
sourcepub fn timestamp(&self) -> i64
pub fn timestamp(&self) -> i64
Returns the number of non-leap seconds since January 1, 1970 0:00:00 UTC (aka “UNIX timestamp”).
sourcepub fn timestamp_millis(&self) -> i64
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);
sourcepub fn timestamp_nanos(&self) -> i64
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);
sourcepub fn timestamp_subsec_millis(&self) -> u32
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
sourcepub fn timestamp_subsec_micros(&self) -> u32
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
sourcepub fn timestamp_subsec_nanos(&self) -> u32
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
sourcepub fn with_timezone<Tz2>(&self, tz: &Tz2) -> DateTime<Tz2> where
Tz2: TimeZone,
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).
sourcepub fn naive_utc(&self) -> NaiveDateTime
pub fn naive_utc(&self) -> NaiveDateTime
Returns a view to the naive UTC datetime.
sourcepub fn naive_local(&self) -> NaiveDateTime
pub fn naive_local(&self) -> NaiveDateTime
Returns a view to the naive local datetime.
sourcepub fn to_rfc2822(&self) -> String
pub fn to_rfc2822(&self) -> String
Returns an RFC 2822 date and time string such as Tue, 1 Jul 2003 10:52:37 +0200
.
sourcepub fn to_rfc3339(&self) -> String
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
.
sourcepub fn to_rfc3339_opts(&self, secform: SecondsFormat, use_z: bool) -> String
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");
sourcepub 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.
sourcepub fn format(&self, fmt: &'a str) -> DelayedFormat<StrftimeItems<'a>>
pub fn format(&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.
