/**
* Obtains a {@code Duration} representing the duration between two temporal objects.
* <p>
* This calculates the duration between two temporal objects. If the objects
* are of different types, then the duration is calculated based on the type
* of the first object. For example, if the first argument is a {@code LocalTime}
* then the second argument is converted to a {@code LocalTime}.
* <p>
* The specified temporal objects must support the {@link ChronoUnit#SECONDS SECONDS} unit.
* For full accuracy, either the {@link ChronoUnit#NANOS NANOS} unit or the
* {@link ChronoField#NANO_OF_SECOND NANO_OF_SECOND} field should be supported.
* <p>
* The result of this method can be a negative period if the end is before the start.
* To guarantee to obtain a positive duration call {@link #abs()} on the result.
*
* @param Temporal $startInclusive the start instant, inclusive, not null
* @param Temporal $endExclusive the end instant, exclusive, not null
* @return Duration a {@code Duration}, not null
* @throws DateTimeException if the seconds between the temporals cannot be obtained
* @throws ArithmeticException if the calculation exceeds the capacity of {@code Duration}
