Source

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)
        .to_offset(offset!(-1))
        .year(),
    1999,

§Panics

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

pub const fn checked_to_offset( self, offset: UtcOffset, ) -> Option<OffsetDateTime>

Convert the OffsetDateTime from the current UtcOffset to the provided UtcOffset, returning None if the date-time in the resulting offset is invalid.

assert_eq!(

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

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

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