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.

Public Constructors

public Timestamp (int theYear, int theMonth, int theDate, int theHour, int theMinute, int theSecond, int theNano)

Since: API Level 1

This constructor is deprecated.
Use the constructor Timestamp(long).

Returns a Timestamp corresponding to the time specified by the supplied values for Year, Month, Date, Hour, Minutes, Seconds and Nanoseconds.

Parameters
theYear specified as the year minus 1900.
theMonth specified as an integer in the range [0,11].
theDate specified as an integer in the range [1,31].
theHour specified as an integer in the range [0,23].
theMinute specified as an integer in the range [0,59].
theSecond specified as an integer in the range [0,59].
theNano which defines the nanosecond value of the timestamp specified as an integer in the range [0,999'999'999]
Throws
IllegalArgumentException if any of the parameters is out of range.

public Timestamp (long theTime)

Since: API Level 1

Returns a Timestamp object corresponding to the time represented by a supplied time value.

Parameters
theTime a time value in the format of milliseconds since the Epoch (January 1 1970 00:00:00.000 GMT).

Public Methods

public boolean after (Timestamp theTimestamp)

Since: API Level 1

Returns true if this timestamp object is later than the supplied timestamp, otherwise returns false.

Parameters
theTimestamp the timestamp to compare with this timestamp object.
Returns
  • true if this Timestamp object is later than the supplied timestamp, false otherwise.

public boolean before (Timestamp theTimestamp)

Since: API Level 1

Returns true if this Timestamp object is earlier than the supplied timestamp, otherwise returns false.

Parameters
theTimestamp the timestamp to compare with this Timestamp object.
Returns
  • true if this Timestamp object is earlier than the supplied timestamp, false otherwise.

public int compareTo (Date theObject)

Since: API Level 1

Compares this Timestamp object with a supplied Timestamp object.

Parameters
theObject the timestamp to compare with this Timestamp object, passed as an Object.
Returns
  • 0 if the two Timestamp objects are equal in time
    a value < 0 if this Timestamp object is before the supplied Timestamp and a value
    > 0 if this Timestamp object is after the supplied Timestamp
Throws
ClassCastException if the supplied object is not a Timestamp object.

public int compareTo (Timestamp theTimestamp)

Since: API Level 1

Compares this Timestamp object with a supplied Timestamp object.

Parameters
theTimestamp the timestamp to compare with this Timestamp object, passed in as a Timestamp.
Returns
  • one of the following:
    • 0, if the two Timestamp objects are equal in time
    • < 0, if this Timestamp object is before the supplied Timestamp
    • > 0, if this Timestamp object is after the supplied Timestamp

public boolean equals (Timestamp theTimestamp)

Since: API Level 1

Tests to see if this timestamp is equal to a supplied timestamp.

Parameters
theTimestamp the timestamp to compare with this Timestamp object, passed as an Object.
Returns
  • true if this Timestamp object is equal to the supplied Timestamp object, false otherwise.

public boolean equals (Object theObject)

Since: API Level 1

Tests to see if this timestamp is equal to a supplied object.

Parameters
theObject the object to which this timestamp is compared.
Returns
  • true if this Timestamp object is equal to the supplied Timestamp object
    false if the object is not a Timestamp object or if the object is a Timestamp but represents a different instant in time.
