/**
 * Standard mutable time period implementation.
 * 

* 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. *

* 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}. *

* 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. *
