Struct aws_lambda_events::encodings::MillisecondTimestamp [−][src]
Expand description
Timestamp with millisecond precision.
Tuple Fields
0: DateTime<Utc>
Methods from Deref<Target = DateTime<Utc>>
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.)
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);
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);
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
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.
Examples

"2018-01-26T18:30:09Z");
let pst = FixedOffset::east(8 * 60 * 60);
