/**
* Standard mutable time period implementation.
* <p>
* A time period is divided into a number of fields, such as hours and seconds.
* Which fields are supported is defined by the PeriodType class.
* The default is the standard period type, which supports years, months, weeks, days,
* hours, minutes, seconds and millis.
* <p>
* When this time period is added to an instant, the effect is of adding each field in turn.
* As a result, this takes into account daylight savings time.
* Adding a time period of 1 day to the day before daylight savings starts will only add
* 23 hours rather than 24 to ensure that the time remains the same.
* If this is not the behaviour you want, then see {@link Duration}.
* <p>
* The definition of a period also affects the equals method. A period of 1
* day is not equal to a period of 24 hours, nor 1 hour equal to 60 minutes.
* This is because periods represent an abstracted definition of a time period
* (eg. a day may not actually be 24 hours, it might be 23 or 25 at daylight
* savings boundary). To compare the actual duration of two periods, convert
* both to durations using toDuration, an operation that emphasises that the
* result may differ according to the date you choose.
* <p>
* MutablePeriod is mutable and not thread-safe, unless concurrent threads
* are not invoking mutator methods.
