Timestamp

extends Date

java.lang.Object
↳	java.util.Date
	↳	java.sql.Timestamp

Class Overview

A Java representation of the SQL TIMESTAMP type. It provides the capability of representing the SQL TIMESTAMP nanosecond value, in addition to the regular date/time value which has millisecond resolution.

The Timestamp class consists of a regular date/time value, where only the integral seconds value is stored, plus a nanoseconds value where the fractional seconds are stored.

The addition of the nanosecond value field to the Timestamp object makes it significantly different from the java.util.Date object which it extends. Users should be aware that Timestamp objects are not interchangable with java.util.Date objects when used outside the confines of the java.sql package.
