Interface AbsoluteInstant

All Superinterfaces:
Cloneable, org.gvsig.tools.lang.Cloneable, Instant, Time
public interface AbsoluteInstant extends Instant, org.gvsig.tools.lang.Cloneable

It defines a partial time that does not support every datetime field, and is thus a local time. It cannot be compared to a RelativeInstant, as it does not fully specify an instant in time.

The time it does specify is a local time, and does not include a time zone. An AbsoluteInstant supports a subset of the fields on the chronology.

A huge part of the documentation of this class has been retrieved from the joda-time library.
