Tony Wu commented on HARMONY-5461:
----------------------------------

Hi, Pavel
This testcase fails on RI too for me...I'm confused since it does not looked like it is related
to default locale/timezone.
I tried on RI5 and RI6, both of them print,

> The following test passes on RI but fails on Harmony:
> ------------------------
> import java.util.TimeZone;
> import java.util.Date;
> class TimeZoneIsDaylight {
>     static Date d = new Date(101, 7, 20);
>     static boolean isDaylight(String s) {
>         return TimeZone.getTimeZone(s).inDaylightTime(d);
>     }
>     static void checkDaylight(String s, boolean yes) {
>         System.out.println(s + ": " + (isDaylight(s) == yes ? "PASSED" : "FAILED"));
>     }
>     public static void main(String[] args) {
>         System.out.println(d);
> 	    checkDaylight("MST", true);
> 	    checkDaylight("EST", true);
>     }
> }
> ------------------------
> The difference is in start month of daylight savings. RI reports it to be March, 8th
for both, we think it is April, 1st.
> I'll attach the patch right now.
