```
    Description copied from class: DurationField
    Computes the difference between two instants, as measured in the units of this field. Any fractional units are dropped from the result. Calling getDifference reverses the effect of calling add. In the following code:
```
 long instant = ...
 int v = ...
 int age = getDifference(add(instant, v), instant);
 
```
    The value 'age' is the same as the value 'v'.
    Overrides:
    
    getDifference in class BaseDurationField
    
    Parameters:
    
    minuendInstant - the milliseconds from 1970-01-01T00:00:00Z to subtract from
    
    subtrahendInstant - the milliseconds from 1970-01-01T00:00:00Z to subtract off the minuend

public long getDifferenceAsLong(long minuendInstant,
                                long subtrahendInstant)
```
    Description copied from class: DurationField
    Computes the difference between two instants, as measured in the units of this field. Any fractional units are dropped from the result. Calling getDifference reverses the effect of calling add. In the following code:
```
 long instant = ...
 long v = ...
 long age = getDifferenceAsLong(add(instant, v), instant);
 
```
    The value 'age' is the same as the value 'v'.
    Overrides:
    
    getDifferenceAsLong in class DecoratedDurationField
    
    Parameters:
    
    minuendInstant - the milliseconds from 1970-01-01T00:00:00Z to subtract from
    
    subtrahendInstant - the milliseconds from 1970-01-01T00:00:00Z to subtract off the minuend
    
    Returns:
    
    the difference in the units of this field
  - getUnitMillis
```
public long getUnitMillis()
```
    Description copied from class: DurationField
    
    Returns the amount of milliseconds per unit value of this field. For example, if this field represents "seconds", then this returns the milliseconds in one second.
    For imprecise fields, the unit size is variable, and so this method returns a suitable average value.
    
    Overrides:
    
    getUnitMillis in class DecoratedDurationField
    
    Returns:
    
    the unit size of this field, in milliseconds

public int getScalar()
```
    Returns the scalar applied, in the field's units.
    
    Returns:
    
    the scalar
  - equals
```
public boolean equals(java.lang.Object obj)
```
    Compares this duration field to another. Two fields are equal if of the same type and duration.
    
    Overrides:
    
    equals in class java.lang.Object
    
    Parameters:
    
    obj - the object to compare to
    
    Returns:
    
    if equal
  - hashCode
