// Java program to demonstrate the

import java.sql.*;
  
public class solution {
    public static void main(String args[])
    {
        // Create two timestamp objects
        Timestamp ts = new Timestamp(10000);
  
        // Display the timestamp object
        System.out.println("Timestamp time: "
                           + ts.toString());
  
        // Set the value of timestamp object
        // using setTime function
        ts.setTime(1000000000);
  
        // Display the new timestamp object
        System.out.println("New Timestamp time: "
                           + ts.toString());
    }
}

Output:

Timestamp time: 1970-01-01 00:00:10.0
New Timestamp time: 1970-01-12 13:46:40.0

Example 2: Create a timestamp and use the setTime() to change the time of timestamp object by passing negative long value as parameter. Giving negative long value represents the time before 1st January 1970
