upgrade for DST2007

We are currently using We are using JDK 5.0 update 6.

Going through articles on upgrade required for JAVA for the

2007 DST rules I am confused.

As per the article below

http://java.sun.com/developer/technicalArticles/Intl/USDST/

J2SE 5.0 Update 6 is fine and will handle the 2007 DST changes.

However as per the article below

http://java.sun.com/developer/technicalArticles/Intl/tzupdatertool.html

According to this article latest Olson data set 2005n was included in JDK/JRE 5.0_7, or later. This article recommends that the version

of JDK/JRE should be 5.0 update 7 or later.

Does anyone know 5.0 update 6 is fine or we need to upgrade to

5.0._7 or later.

Thanks,

Kannan.

Hi Kannan,

I believe tzdata2005m contains the majority of US DST 2007 related changes. A few more timezones decided to change their rules after the US data was published. Timezones within Canada, Brazil, etc. Even as late as Jan2007 new timezone data tzdata2007 was released which incorporates more TZ changes connected to the US DST changes (Bahamas) I also believe Indianapolis is changing Timezone.

Summary : Most US DST changes are in tzdata2005m, however to be up to date with the very latest, you should consider upgrading or using the tzupdater tool : http://java.sun.com/javase/downloads/index.jsp - It may be no harm either to write a simple timezone test that verifies that the TimeZones you are interested in contain the correct data.
