Timestamp Synopsis Class Name java.sql.Timestamp Superclass java.util.Date Immediate Subclasses None Interfaces Implemented None Availability JDK 1.1 Description This class serves as a SQL representation of the Java Date class specifically designed to serve as a SQL TIMESTAMP. It also provides the ability to hold nanoseconds as required by SQL TIMESTAMP values. You should keep in mind that this class uses the java.util.Date version of hashcode . This means that two timestamps that differ only by nanoseconds will have identical hashcode return values. Class Summary public class .
