/**
* Subtracts this period from the specified temporal object.
* <p>
* This returns a temporal object of the same observable type as the input
* with this period subtracted.
* If the temporal has a chronology, it must be the ISO chronology.
* <p>
* In most cases, it is clearer to reverse the calling pattern by using
* {@link Temporal#minus(TemporalAmount)}.
* <pre>
* // these two lines are equivalent, but the second approach is recommended
* dateTime = thisPeriod.subtractFrom(dateTime);
* dateTime = dateTime.minus(thisPeriod);
* </pre>
* <p>
* The calculation operates as follows.
* First, the chronology of the temporal is checked to ensure it is ISO chronology or null.
* Second, if the months are zero, the years are subtracted if non-zero, otherwise
* the combination of years and months is subtracted if non-zero.
* Finally, any days are subtracted.
* <p>
* This approach ensures that a partial period can be subtracted from a partial date.
* For example, a period of years and/or months can be subtracted from a {@code YearMonth},
* but a period including days cannot.
* The approach also subtracts years and months together when necessary, which ensures
* correct behaviour at the end of the month.
* <p>
* This instance is immutable and unaffected by this method call.
*
* @param Temporal $temporal the temporal object to adjust, not null
* @return Temporal an object of the same type with the adjustment made, not null
* @throws DateTimeException if unable to subtract
* @throws ArithmeticException if numeric overflow occurs
