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

    static public Timestamp valueOf(String s);

Description

This constructor creates a new Timestamp object. The first prototype constructs a Timestamp for the year, month, date, hour, minute, second, and nanosecond specified. The second prototype constructs one based on the number of seconds since January 1, 1970, 12:00:00 ...
