– RIM will distribute the script in early February.
– Run the script
1. At the command prompt, switch to the folder in which the script resides.
2. Type osql -E -d databasename -i LoadDSTData.sql
• Note: Upcoming device software releases (i.e. v4.2.1 and beyond) will also have the updated DST information
End User – can check the Options2007 DST Patch
Administrator – DST2007Query.exe determines which devices/users have the patch applied correctly
If the correct patch has been applied to the Microsoft Windows Operating System then calendar synchronization should continue to function normally, regardless of whether any patches have been applied to the BlackBerry® device (for example, if the user chooses to manually change the time).
If the correct patch has been applied to the Microsoft Windows Operating System then BlackBerry Desktop Software v4.2 Service Pack 1 is required to properly synchronize the time. If earlier versions of BlackBerry Desktop Software are used then the wrong time zone information will be sent. For example, 1:00pm Central Standard Time (Mexico) will end up being 1:00pm GMT on the device. It is recommended that this Time/Date Synchronization be disabled until the new BlackBerry Desktop Software v4.2 Service Pack 1 is installed in this case. Learn how to update the registry to change this setting.
It depends on the OS to calculate date and time information. The U.S. Daylight Savings Time changes for 2007 will cause incorrect Universal Time Coordinated (UTC) conversions with ColdFusion 5. Even when the OS patch for DST is applied, ColdFusion 5.0 continues to use the original DST information on patched systems, and will miscompute local time to UTC (Local2UTC) and UTC to local time (UTC2Local) conversion made with the dateConvert function during daylight savings time. All other ColdFusion 5.0 date and time functions will use the updated DST information and perform the appropriate date and time evaluations correctly.
Apply the appropriate OS patch to install the updated DST information
Manually edit ColdFusion 5’s dateConvert function. See example in the KB400365
The current time is calculated correctly in ColdFusion MX and higher, regardless of whether the Automatically Adjust Clock for Daylight Saving Changes option is enabled or disabled in the computer's Control panel Date/Time Properties. This is because the application is build on top of Java.
ColdFusion MX and JRun are Java applications that depend on the Sun Java Virtual Machine (JVM) for their time information. The new US Daylight Savings Time changes for 2007 will affect ColdFusion MX and JRun because of this.
