I have the following test program, which gets the current time and
date, prints it out, and then adds one day at a time to it for the
bext 30 days.

After transitioning from PDT to PST, the date and time printed out is
wrong:

Next time: Sat Oct 25 12:55:07 PST 1997
Next time: Sat Sep 06 20:52:20 PDT 1997


Here's the test program:

import java.util.*;

public class Test1 {

    public static void main(String[] argv) {

Date firstDate = new Date();
System.err.println("Current time: " + firstDate.toString());

for (int validity=0; validity<30; validity++) {
Date lastDate = new Date(firstDate.getTime() +
validity*1000*24*60*60);
System.err.println("Next time: " + lastDate.toString());
}
    }
}


Here's the test program's output:

Current time: Wed Oct 01 13:55:07 PDT 1997
