- Method Detail
  - isPrecise
```
public boolean isPrecise()
```
    Description copied from class: DurationField
    
    Is this field precise. A precise field can calculate its value from milliseconds without needing a reference date. Put another way, a precise field's unit size is not variable.
    
    Specified by:
    
    isPrecise in class DurationField
    
    Returns:
    
    true if precise

    DurationField.getUnitMillis()
  - 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.
    
    Specified by:
    
    getUnitMillis in class DurationField
    
    Returns:
    
    the unit size of this field, in milliseconds

  - getValue
```
public int getValue(long duration,
                    long instant)
```
    Description copied from class: BaseDurationField
    
    Get the value of this field from the milliseconds relative to an instant.
    If the milliseconds is positive, then the instant is treated as a "start instant". If negative, the instant is treated as an "end instant".
    The default implementation returns Utils.safeToInt(getAsLong(millisDuration, instant)).
    
    Overrides:
    
    getValue in class BaseDurationField
    
    Parameters:
    
    duration - the milliseconds to query, which may be negative
    
    instant - the start instant to calculate relative to
    
    Returns:
    
    the value of the field, in the units of the field, which may be negative
  - getValueAsLong
```
public long getValueAsLong(long duration,
                           long instant)
```
    Description copied from class: DurationField
    
    Get the value of this field from the milliseconds relative to an instant. For precise fields this method produces the same result as for the single argument get method.
    If the millisecond duration is positive, then the instant is treated as a "start instant". If negative, the instant is treated as an "end instant".
    
    Specified by:
    
    getValueAsLong in class DurationField
    
    Parameters:
    
    duration - the milliseconds to query, which may be negative
    
    instant - the start instant to calculate relative to
    
    Returns:
    
    the value of the field, in the units of the field, which may be negative
  - getMillis
```
public long getMillis(int value,
                      long instant)
```
    Description copied from class: DurationField
    
    Get the millisecond duration of this field from its value relative to an instant. For precise fields this method produces the same result as for the single argument getMillis method.
    If the value is positive, then the instant is treated as a "start instant". If negative, the instant is treated as an "end instant".
    
    Specified by:
    
    getMillis in class DurationField
    
    Parameters:
    
    value - the value of the field, which may be negative
    
    instant - the instant to calculate relative to
    
    Returns:
    
    the millisecond duration that the field represents, which may be negative
  - getMillis
```
public long getMillis(long value,
                      long instant)
```
    Description copied from class: DurationField
    
    Get the millisecond duration of this field from its value relative to an instant. For precise fields this method produces the same result as for the single argument getMillis method.
    If the value is positive, then the instant is treated as a "start instant". If negative, the instant is treated as an "end instant".
    
    Specified by:
    
    getMillis in class DurationField
    
    Parameters:
    
    value - the value of the field, which may be negative
    
    instant - the instant to calculate relative to
    
    Returns:
    
    the millisecond duration that the field represents, which may be negative
  - add
```
public long add(long instant,
                int value)
```
    Description copied from class: DurationField
    
    Adds a duration value (which may be negative) to the instant.
    
    Specified by:
    
    add in class DurationField
    
    Parameters:
    
    instant - the milliseconds from 1970-01-01T00:00:00Z to add to
    
    value - the value to add, in the units of the field
    
    Returns:

                long value)
```
    Description copied from class: DurationField
    
    Adds a duration value (which may be negative) to the instant.
    
    Specified by:
    
    add in class DurationField
    
    Parameters:
    
    instant - the milliseconds from 1970-01-01T00:00:00Z to add to

  - getDifference
```
public int getDifference(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 = ...
 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
    
    Returns:
    
    the difference in the units of this field

```
    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:
