The TimeZone code fails to handle transitions at MIDNIGHT
correctly. This will show up both in custom zones and also
the system zones for Syria (Asia/Damascus), Israel
(Asia/Jerusalem), Pacific/Rarotonga, and America/Asuncion.

In the following output, the time should transition from
Sept 30 23:00 Daylight to
Sept 30 23:00 Standard to
Oct 1 0:00 Standard

Instead, here is the test output:
0: Wed Sep 30 22:00:00 GMT+03:00 1998
1: Wed Sep 30 23:00:00 GMT+03:00 1998
2: Thu Oct 01 00:00:00 GMT+03:00 1998 <- wrong
3: Thu Oct 01 00:00:00 GMT+02:00 1998
4: Thu Oct 01 01:00:00 GMT+02:00 1998

Once this is fixed, additional code must be added to make
SimpleTimeZone understand leap years; currently, it fails to
do so. If it does not add this capability, certain days
(such as February 29, 2000) will be handled incorrectly.

Here is the test.

import java.util.*;
public class bug2 {
    public static void main(String[] args) {
        TimeZone tz = TimeZone.getTimeZone("Asia/Damascus");
        TimeZone.setDefault(tz);
        Date d = new Date(98, Calendar.SEPTEMBER, 30, 22, 0);
        for (int i=0; i<5; ++i) {
            System.out.println("" + i + ": " + d);
            d = new Date(d.getTime() + 3600000);
        }
    }
}
