Just had this forwarded on to me. Hopefully it has no effects on the AR System.
DST Sun Alert attached It's important to note that this problem comes into play only if BOTH of the following conditions are met: 1) The JRE is using the one of the following 3 letter time zone designations: EST, MST or HST. Note that these have been deprecated. The preferred/recommended time zone designation is the long format: "US/Eastern" or "America/New_York." 2) The system is using JRE version 1.4.2_12 or later, or any JRE version 1.4.x/1.5.x that has had the tzupdater tool run against it. The effect of encountering the issue is that times would be one hour off, showing as 11 pm EDT when it's really 10 pm EDT, for example. If you have at-risk systems, there are two simple fixes: 1) Remove the three files <jrehome>/jre/lib/zi/{EST,MST,HST} So if your jrehome is /usr/java, then # rm /usr/java/jre/lib/zi/EST will fix the problem for EST, repeat above command for MST and HST. and, for a complete 2005 DST fix 2) run The Sun Java SE TZupdater tool with -f -bc as follows: # <jrehome>/jre/java -jar /tmp/<tzupdater dir>/tzupdater.jar -f -bc assuming that the tzupdater package was downloaded and unzipped in /tmp amd jrehome is where the JRE is installed. ________________________________ Document Audience: PUBLIC Document ID: 102836 Title: Olson TZ Data (tzdata2005r or greater) Incompatibility Issues Copyright Notice: Copyright © 2007 Sun Microsystems, Inc.

Impact The introduction of Olson Timezone (TZ) data, version 2005r or greater, may break backward compatibility for the Eastern, Hawaiian, and Mountain time zones, under certain circumstances. This issue is also outlined in Sun BugIDs 6466476 and 6530336, listed at: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6466476 http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6530336 Note: The Hawaiian TZ is only affected for historical data. Other American TZs such as PST and CST are not affected. 2. Contributing Factors This issue can occur in the following releases for all platforms: * JDK and JRE v1.4.2_12 and above * JDK and JRE 5.0u8 and above * JDK and JRE 6 and above Notes: 1. Releases below Java SE v1.4.x are not affected by this issue. 2. The condition will also exist if you have run the "Time Zone Updater Tool" for v1.4.x+, but without the -bc flag. This condition will be apparent under one of the following two circumstances: A) The use of old 3-letter TZ IDs, limited to: "EST", "HST", "MST". Or: B) The parsing of date strings containing one of the following three TZ strings: "EDT", "HDT", or "MDT". 3. Symptoms The symptoms/result of this condition will be that Daylight Dave -------------------------- [EMAIL PROTECTED] (Wireless)
