public class MutablePeriod extends BasePeriod implements ReadWritablePeriod, Cloneable, Serializable
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 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.
MutablePeriod is mutable and not thread-safe, unless concurrent threads are not invoking mutator methods.

Only precise fields in the period type will be used. For the standard period type this is the time fields only. Thus the year, month, week and day fields will not be populated.
If the duration is small, less than one day, then this method will perform as you might expect and split the fields evenly.
If the duration is larger than one day then all the remaining duration will be stored in the largest available precise field, hours in this case.
For example, a duration equal to (365 + 60 + 5) days will be converted to ((365 + 60 + 5) * 24) hours by this constructor.
For more control over the conversion process, you have two options:
