Implementations

impl OffsetDateTime

pub const UNIX_EPOCH: OffsetDateTime

Midnight, 1 January, 1970 (UTC).

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

pub fn now_utc() -> OffsetDateTime

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

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

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

assert_eq!(
    datetime!(2000-01-01 0:00 UTC)

        .year(),
    1999,
);

) -> Result<OffsetDateTime, ComponentRange>

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