Description

build: /net/jano/export/disk29/jcg/NightlyBuilds/i18n/mustang/archived/2006-05-19-int.mustang
OS: Windows Vista 32 bit, build 5365
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.

Comments

EVALUATION Vista doesn't have the DisableAutoDaylightTimeSet entry in the TimeZoneInformation registry. Need to compare the detected TimeZones entry and TimeZoneInformation to see if the daylight saving time adjustment is currently disabled.
