The standard dates for North American Daylight Saving Time (DST) change in March 2007. Previously, DST began on the first Sunday in April and ended on the last Sunday in October. As of March 2007, DST begins on the second Sunday in March and ends on the first Sunday in November. Visit

When the DST dates change in March 2007, the BlackBerry device will not update the clock for the affected time zones. As a result, the BlackBerry device might not display correct time zone information.
Single instance and recurring appointments, and the reminders for those appointments, might appear 1 hour late on the BlackBerry device if the appointments start in one of the following windows in any year:
between the second Sunday in March and the first Sunday in April; for example, 11 March 2007 to 1 April 2007
between the last Sunday in October and the first Sunday in November; for example, 28 October 2007 to 4 November 2007
You might experience the following calendar events when the DST dates change in March 2007:
If the calendar on the BlackBerry device synchronizes with the email application on your computer, your appointment start times might appear incorrectly on the BlackBerry device.
If you create a recurring appointment that starts in the specified windows, all instances of the appointment might appear incorrectly in the calendar on the BlackBerry device.
If you accept a request to a meeting that is scheduled to start in the specified windows, the appointment might appear incorrectly in the calendar on the BlackBerry device.
If you schedule a meeting to start in the specified windows, the appointment might appear incorrectly in attendees' calendars.
As a result of the new DST dates in North America, several new time zones are being introduced globally in 2007. The introduction of these new time zones might cause further inconsistencies in the calendar on the BlackBerry device, because these new time zones do not yet exist in the BlackBerry Device Software or in the BlackBerry Enterprise Server.
Resolution
Users can change the time on the BlackBerry device manually at the start and end of the new and old DST dates. Changing the time alone is sufficient for users who do not use their calendars actively and synchronize it with a PC. To update the DST information for the BlackBerry Device Software and BlackBerry Enterprise Server, you must apply patches to all versions of the software. These patches will be available in late January 2007. Please use the links below for more information.
