        Description

        build: JDK6 b95
        OS: Windows Vista 32 bit, build 5487 and 5520
        host: i18n-gw65002-2
        Test: test/java/util/TimeZone/DisableDSTTest.java

        To reproduce:
        1. Run jtreg with DisableDSTTest.java
        2. when "Automatically adjust clock for daylight saving changes" is unchecked on the the local time still shows as daylight saving time; while on a Windows XP the local time shows as standard time as expected.

        The test worked fine on a Windows vista 64bit, ja version, build 5456.

        The behaviors between b91 and b92(and up) are a little different:
        starting from b92 and up to b95, it doesn't show any difference on the test whether "Automatically adjust clock for daylight saving changes" is checked or not, it always shows the daylight saving time.
        While for b91, when it is unchecked, the time on test shows as "Greenwich" time, it shows correct time when "Automatically adjust clock for daylight saving changes" is checked.
