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.

assert!(OffsetDateTime::now_utc().year() >= 2019);

);
assert_eq!(dt, datetime!(2024-01-01 12:59:59.5 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)
        .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));

        .assume_utc()
        .checked_to_offset(offset!(+1)),
    None,
);

pub const fn to_utc(self) -> UtcDateTime

assert_eq!(
    datetime!(2000-01-01 0:00 +1)
        .to_utc()
