impl OffsetDateTime

source

pub const UNIX_EPOCH: Self = _

Midnight, 1 January, 1970 (UTC).

assert_eq!(OffsetDateTime::UNIX_EPOCH, datetime!(1970-01-01 0:00 UTC),);
Run
source

pub fn now_utc() -> Self

Create a new OffsetDateTime with the current date and time in UTC.

assert!(OffsetDateTime::now_utc().year() >= 2019);
assert_eq!(OffsetDateTime::now_utc().offset(), offset!(UTC));
Run
source

pub const fn to_offset(self, offset: UtcOffset) -> Self

Convert the OffsetDateTime from the current UtcOffset to the provided UtcOffset.

assert_eq!(
    datetime!(2000-01-01 0:00 UTC)
        .to_offset(offset!(-1))
        .year(),
    1999,
);

// Let's see what time Sydney's new year's celebration is in New York and Los Angeles.

// Construct midnight on new year's in Sydney.
let sydney = datetime!(2000-01-01 0:00 +11);
let new_york = sydney.to_offset(offset!(-5));

Panics

This method panics if the local date-time in the new offset is outside the supported range.

pub const fn from_unix_timestamp(timestamp: i64) -> Result<Self, ComponentRange>

Create an OffsetDateTime from the provided Unix timestamp. Calling .offset() on the resulting value is guaranteed to return UTC.

assert_eq!(
    OffsetDateTime::from_unix_timestamp(0),

Run

If you have a timestamp-nanosecond pair, you can use something along the lines of the following:

let (timestamp, nanos) = (1, 500_000_000);
assert_eq!(
    OffsetDateTime::from_unix_timestamp(timestamp)? + Duration::nanoseconds(nanos),
    OffsetDateTime::UNIX_EPOCH + 1.5.seconds()
);
Run
