DST 2007 and SteelEye Products (by Dave Bermingham)

The Energy Policy Act of 2005 impacts Daylight Savings Time in the United States by extending it by one month. 

What this means for the United States and other countries which followed suit is that daylight savings will start earlier and end later.  Beginning in 2007, Daylight Saving Time begins for most of the United States at 2 a.m. on the Second Sunday in March and ends at 2 a.m. on the First Sunday of November.

What does this mean to you besides losing an hour of sleep in March?  Well, software that does not take the new Energy Policy Act of 2005 into account will minimally report wrong dates for a period of time; this includes everything from digital watches to complex control systems.  Software that is more time sensitive may in fact fail completely.

Here at SteelEye Technology, we realize that failure is not an option when it comes to protecting your business critical systems.  Therefore, we have done extensive testing against all of our solutions and have found no issues with our core applications in regards to the DST 2007 change.  However, there are some known issues with Java, a key piece of the complete LifeKeeper solution.  The complete details of the Java problems can be found here: http://java.sun.com/developer/technicalArticles/Intl/USDST/

We recommend that all of our customers apply any relevant OS or application patch provided by their vendor.  Beyond that, you have the following choice as far as LifeKeeper is concerned:

1. Do nothing and everything will work except the LK GUI client display messages will show the time incorrectly in a few locations. All logged information will continue to show the correct time.  The only time the GUI would be incorrect would be from March 11, 2007 through April 2, 2007 and from October 29, 2007 through November 4, 2007 and subsequent years during the overlap period prior to the changes introduced in DST 2007.

2. Upgrade LifeKeeper to the latest version which is 6.1.1 and it includes JRE 1.5.X which has the problem fixed.

Many Life keeper have older JRE
e.g 1.3.1_18 should fix it as well if you use 1.3.1
