示例1: standardPeriodIn
import org.joda.time.field.FieldUtils; //导入方法依赖的package包/类
/**
* Creates a new instance representing the number of complete standard length units
* in the specified period.
* <p>
* This factory method converts all fields from the period to hours using standardised
* durations for each field. Only those fields which have a precise duration in
* the ISO UTC chronology can be converted.
* <ul>
* <li>One week consists of 7 days.
* <li>One day consists of 24 hours.
* <li>One hour consists of 60 minutes.
* <li>One minute consists of 60 seconds.
* <li>One second consists of 1000 milliseconds.
* </ul>
* Months and Years are imprecise and periods containing these values cannot be converted.
*
* @param period the period to get the number of hours from, must not be null
* @param millisPerUnit the number of milliseconds in one standard unit of this period
* @throws IllegalArgumentException if the period contains imprecise duration values
