 /**
  * Creates a period from the given duration and end point.
  *
  * <p>The two partials must contain the same fields, thus you can specify two <code>LocalDate
  * </code> objects, or two <code>LocalTime</code> objects, but not one of each. As these are
  * 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
  * @since 1.1
