BaseDateTimeField
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

The value will be added to this field. If the value is too large to be added solely to this field then it wraps. Larger fields are always unaffected. 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 addWrapField six months is 2000-02-20
2000-08-20 addWrapField twenty months is 2000-04-20
2000-08-20 addWrapField minus nine months is 2000-11-20
2001-01-31 addWrapField one month is 2001-02-28
2001-01-31 addWrapField two months is 2001-03-31
The default implementation internally calls set. Subclasses are encouraged to provide a more efficient implementation.

public long roundFloor(long instant)
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.

BaseDateTimeField
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.

BaseDateTimeField
For example, on a datetime of 2002-11-02T23:34:56.789, the remainder by hour is 34 minutes and 56.789 seconds.
The default implementation computes
instant - roundFloor(instant)
. Subclasses are encouraged to
provide a more efficient implementation.
