Hi,
Changes in Daylight Savings for 2007 scheduled to take effect on 3-11-2007 will affect Java applications in the United States.

Updated Java Runtime Environments contain updated rules to report appropriate time with respect to the time zone.
Users in the USA who are running DeviceExpert build number 4210 or lesser are requested to patch the JRE. Please follow the instructions below to patch the JRE.
