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

BaseDateTimeField
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

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.

BaseDateTimeField
For example, a datetime of 2002-11-02T23:34:56.789, rounded to the lowest whole hour is 2002-11-02T23:00:00.000.

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.
