- Method Detail
  - parse
```
public static Duration parse(String input)
```
    Parses a duration.
    
    Parameters:
    
    input - a duration in ISO 8601 format
    
    Returns:
    
    a new instance representing the same duration as the input
  - create
```
public static Duration create(int amount,
                              Unit unit)
```
  - add
```
public Duration add(Duration d)
```
  - amount
```
public int amount(Unit unit)
```
  - forward
```
public void forward(Calendar cal)
```
  - back
```
public void back(Calendar cal)
```
  - next
```
public void next(Calendar cal)
```
    Moves the calendar to the next position, as if divided into pieces of time with the length defines by this Duration.
    For instance, a duration of P1M will move the calendar to the start of next month. If the calendar is set to January 12, this method will move the calendar February 1. If set to February, this method will move the calendar to March 1.
    
    Parameters:
    
    cal - The calendar to move to the next position.
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - equals
```
public boolean equals(Object o)
```
    True if the argument is a duration with the same or equivalent specification. Note that P1W equals P7D by definition, whereas e.g. P1M does not equal P30D since months are not 30 days in general. Less obvious, P1D is not equal to P24H in general.
    Years are normalized to months, weeks to days and hours and minutes to seconds. After normalization, both durations are compared component by component. Iff all components match, this method returns true.
    
    Overrides:
    
    equals in class Object
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - fromMillis
```
public static Duration fromMillis(long millis)
```
  - precision
```
public Unit precision()
```
  - toMillis
```
public long toMillis()
```
    Calculated as if it was an interval from 1 Jan 1970 00:00 UTC and forward.
    
    Returns:
    
    duration to milliseconds.
  - toDays
```
public long toDays()
```
    Calculated as if it was an interval from 1 Jan 1970 00:00 UTC and forward.
    
    Returns:
    
    duration as days
