    [ https://issues.apache.org/jira/browse/HARMONY-6410?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12793477#action_12793477

Nathan Beyer commented on HARMONY-6410:

Note - Time zone information and display names are not guaranteed to be consistent across
JREs. Time zone information will depend upon several factors - the version of the JRE being
used, the version of the time zone info database being used and other factors. The display
names are localization details.

Can you define what Sun JDK was used in this test? What version of the zoneinfo database is

What version of Harmony is used?

> When running the testcase:org.apache.harmony.luni.tests.java.util.TimeZoneTest#test_getDSTSavings(),
on sun's jdk
>         TimeZone st1 = TimeZone.getTimeZone("EST");
>         assertEquals("T1A. Incorrect daylight savings returned", ONE_HOUR, st1
>                 .getDSTSavings());
> this assertion failed, expect 36000, actually return 0.
> and another testcase:org.apache.harmony.luni.tests.java.util.TimeZoneTest#test_getDisplayNameZILjava_util_Locale(),
on sun's jdk
>         TimeZone timezone = TimeZone.getTimeZone("Asia/Shanghai");
>         assertEquals("\u683c\u6797\u5c3c\u6cbb\u6807\u51c6\u65f6\u95f4+0800",
>                 timezone.getDisplayName(false, TimeZone.SHORT, Locale.CHINA));
> this assertion failed, expected was "格林尼治标准时间+0800" but actually return
> while both testcases succeded in hamony's jdk.
