Java Calculate Number of Seconds Between two OffsetDateTime

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

public class SecondsBetweenOffsetDateTimeExample {
    public static void main(String... args) {
        OffsetDateTime startOffsetDateTime = OffsetDateTime.parse("2022-08-14T07:00:00.00+07:00");
        OffsetDateTime endOffsetDateTime = OffsetDateTime.parse("2022-08-14T07:30:00.00+07:00");

        // Calculate Number of Seconds Between two OffsetDateTime
        long numberOfSeconds = ChronoUnit.SECONDS.between(startOffsetDateTime, endOffsetDateTime);

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

Number of seconds between 2022-08-14T07:00+07:00 and 2022-08-14T07:30+07:00 is 1800
