- def durationToMicros(duration: Duration): Long
Converts this duration to the total length in microseconds.
Converts this duration to the total length in microseconds.
If this duration is too large to fit in a Long microseconds, then an exception is thrown.
If this duration has greater than microsecond precision, then the conversion will drop any excess precision information as though the amount in nanoseconds was subject to integer division by one thousand.
- returns
The total length of the duration in microseconds

- def monthsToPeriod(months: Int): Period
Obtains a Period representing a number of months.
Obtains a Period representing a number of months. The days unit will be zero, and the years and months units will be normalized.
The months unit is adjusted to have an absolute value < 12, with the years unit being adjusted to compensate. For example, the method returns "2 years and 3 months" for the 27 input months.
The sign of the years and months units will be the same after normalization. For example, -13 months will be converted to "-1 year and -1 month".
- months
The number of months, positive or negative
- returns
The period of months, not null

- def periodToMonths(period: Period): Int
Gets the total number of months in this period.
Gets the total number of months in this period.
This returns the total number of months in the period by multiplying the number of years by 12 and adding the number of months.
