```
public long add(long instant,
                int value)
```
    Description copied from class: BaseDateTimeField
    
    Adds a value (which may be negative) to the instant value, overflowing into larger fields if necessary.
    The value will be added to this field. If the value is too large to be added solely to this field, larger fields will increase as required. Smaller fields should be unaffected, except where the result would be an invalid value for a smaller field. In this case the smaller field is adjusted to be in range.
    For example, in the ISO chronology:
    2000-08-20 add six months is 2001-02-20
    2000-08-20 add twenty months is 2002-04-20
    2000-08-20 add minus nine months is 1999-11-20
    2001-01-31 add one month is 2001-02-28
    2001-01-31 add two months is 2001-03-31
    
    Overrides:
    
    add in class BaseDateTimeField
    
    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:
    
    the updated milliseconds
  - add
```
public long add(long instant,
                long value)
```
    Description copied from class: BaseDateTimeField
    
    Adds a value (which may be negative) to the instant value, overflowing into larger fields if necessary.
    
    Overrides:
    
    add in class BaseDateTimeField
    
    Parameters:
    
    instant - the milliseconds from 1970-01-01T00:00:00Z to add to
    
    value - the long value to add, in the units of the field
    
    Returns:
    
    the updated milliseconds
    
    See Also:
    
    BaseDateTimeField.add(long,int)
  - add
```
public int[] add(ReadablePartial partial,
                 int fieldIndex,
                 int[] values,
                 int valueToAdd)
```
    Description copied from class: BaseDateTimeField
    
    Adds a value (which may be negative) to the partial instant, throwing an exception if the maximum size of the instant is reached.
    The value will be added to this field, overflowing into larger fields if necessary. Smaller fields should be unaffected, except where the result would be an invalid value for a smaller field. In this case the smaller field is adjusted to be in range.
    Partial instants only contain some fields. This may result in a maximum possible value, such as TimeOfDay being limited to 23:59:59:999. If this limit is breached by the add an exception is thrown.
    For example, in the ISO chronology:
    2000-08-20 add six months is 2000-02-20
    2000-08-20 add twenty months is 2000-04-20
    2000-08-20 add minus nine months is 2000-11-20
    2001-01-31 add one month is 2001-02-28
    2001-01-31 add two months is 2001-03-31

```
    Description copied from class: BaseDateTimeField
    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 BaseDateTimeField
    
    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

    the difference in the units of this field
  - getDifferenceAsLong
```
public long getDifferenceAsLong(long minuendInstant,
                                long subtrahendInstant)
```
    Description copied from class: BaseDateTimeField
    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 BaseDateTimeField
    
    Parameters:
    
    minuendInstant - the milliseconds from 1970-01-01T00:00:00Z to subtract from

                int value)
```
    Description copied from class: BaseDateTimeField
    
    Sets a value in the milliseconds supplied.
    The value of this field will be set. If the value is invalid, an exception if thrown.
    If setting this field would make other fields invalid, then those fields may be changed. For example if the current date is the 31st January, and the month is set to February, the day would be invalid. Instead, the day would be changed to the closest value - the 28th/29th February as appropriate.

    partial - the partial instant to query
    
    Returns:
    
    the maximum value for this field, in the units of the field
  - getMaximumValue
```
public int getMaximumValue(ReadablePartial partial,
                           int[] values)
```
    Description copied from class: BaseDateTimeField
    
    Get the maximum value for this field using the partial instant and the specified values.
    This implementation returns the same as BaseDateTimeField.getMaximumValue(ReadablePartial).
    
    Overrides:
    
    getMaximumValue in class BaseDateTimeField
    
    Parameters:
    
    partial - the partial instant to query
    
    values - the values to use
    
    Returns:
    
    the maximum value for this field, in the units of the field
  - roundFloor
```
public long roundFloor(long instant)
```
    Description copied from class: BaseDateTimeField
    
    Round to the lowest whole unit of this field. After rounding, the value of this field and all fields of a higher magnitude are retained. The fractional millis that cannot be expressed in whole increments of this field are set to minimum.
    For example, a datetime of 2002-11-02T23:34:56.789, rounded to the lowest whole hour is 2002-11-02T23:00:00.000.
    
    Specified by:
    
    roundFloor in class BaseDateTimeField
    
    Parameters:
    
    instant - the milliseconds from 1970-01-01T00:00:00Z to round
    
    Returns:
    
    rounded milliseconds
  - roundCeiling
```
public long roundCeiling(long instant)
```
    Description copied from class: BaseDateTimeField
    
    Round to the highest whole unit of this field. The value of this field and all fields of a higher magnitude may be incremented in order to achieve this result. The fractional millis that cannot be expressed in whole increments of this field are set to minimum.
    For example, a datetime of 2002-11-02T23:34:56.789, rounded to the highest whole hour is 2002-11-03T00:00:00.000.
    The default implementation calls roundFloor, and if the instant is modified as a result, adds one field unit. Subclasses are encouraged to provide a more efficient implementation.
    
    Overrides:
    
    roundCeiling in class BaseDateTimeField
    
    Parameters:
    
    instant - the milliseconds from 1970-01-01T00:00:00Z to round
    
    Returns:
    
    rounded milliseconds
  - getMaximumTextLength
```
public int getMaximumTextLength(java.util.Locale locale)
```
    Description copied from class: BaseDateTimeField
    
    Get the maximum text value for this field. The default implementation returns the equivalent of Integer.toString(getMaximumValue()).length().
    
    Overrides:
    
    getMaximumTextLength in class BaseDateTimeField
    
    Parameters:
    
    locale - the locale to use for selecting a text symbol
    
    Returns:
    
    the maximum text length
  - getMaximumShortTextLength
```
public int getMaximumShortTextLength(java.util.Locale locale)
```
    Description copied from class: BaseDateTimeField
    
    Get the maximum short text value for this field. The default implementation returns getMaximumTextLength().
    
    Overrides:
    
    getMaximumShortTextLength in class BaseDateTimeField
    
    Parameters:
    
    locale - the locale to use for selecting a text symbol
    
    Returns:
    
    the maximum short text length
