Java Calculate Number of Nanoseconds Between two OffsetDateTime

import java.time.OffsetDateTime;
import java.time.temporal.ChronoUnit;

public class NanosecondsBetweenOffsetDateTimeExample {
    public static void main(String... args) {
        OffsetDateTime startOffsetDateTime = OffsetDateTime.parse("2022-08-14T07:00:00.00+07:00");
        OffsetDateTime endOffsetDateTime = OffsetDateTime.parse("2022-08-14T07:00:01.00+07:00");

        // Calculate Number of Nanoseconds Between two OffsetDateTime
        long numberOfNanoseconds = ChronoUnit.NANOS.between(startOffsetDateTime, endOffsetDateTime);

        System.out.println(String.format("Number of nanoseconds between %s and %s is %d",
                startOffsetDateTime,
                endOffsetDateTime,
                numberOfNanoseconds));
    }
}

Number of nanoseconds between 2022-08-14T07:00+07:00 and 2022-08-14T07:00:01+07:00 is 1000000000
