  SimpleTimeZone ctors, setStartRule and setEndRule works wrong when setting a day-of-month rule with negative
day of month. The rules are illegal since the day should be greater than 0. But the methods don't throw any
IllegalArgumentException for such rules.

Here is a test demonstrating the bug.
---------------SimpleTimeZoneTest.java---------
import java.util.SimpleTimeZone;

public class SimpleTimeZoneTest {
  public static void main(String args[]) {
    try {
      SimpleTimeZone zone = new SimpleTimeZone(
        0, "ID",
        0, -1, 0, 0,
        0, 0, 0, 0
      );

      System.out.println("Failed. No exception has been thrown");
    } catch(IllegalArgumentException e) {
      System.out.println("Passed.");
    }
  }
}
-------------The test output-----------
> java -version
java version "1.2fcs"
Classic VM (build JDK-1.2fcs-O, green threads, sunwjit)
> java SimpleTimeZoneTest
Failed. No exception has been thrown
