* Partial objects, time zones have no effect on the result.
*
* <p>The two partials must also both be contiguous - see {@link
* DateTimeUtils#isContiguous(ReadablePartial)} for a definition. Both <code>LocalDate</code> and
* <code>LocalTime</code> are contiguous.
*
* @param start the start of the period, must not be null
* @param end the end of the period, must not be null
* @param type which set of fields this period supports, null means standard
* @throws IllegalArgumentException if the partials are null or invalid
