How does Daylight Saving Time affect the system?

Our Java-based software relies on the underlying Java runtime for the correct time, so you will have to update your Java runtime. In addition to Java, system administrators and users will have to update their underlying operating systems — Windows, Linux, AIX, and so on.

Note

Windows XP has a Daylight Saving Time change as part of its regular updates. For information on other operating systems, check with your vendor.

Here are links to information on how you can update your Java runtime. In addition to runtime updates, both Sun and IBM offer time zone updating utilities that update your in-place installations of Java. You will find more information in these links:
