Impact on the BlackBerry Device Calendar

  1. Will appointments on the BlackBerry device Calendar be affected?
    Yes, appointments with a start date falling within any affected periods may be displayed incorrectly.
     
  2. Which of my appointments may be affected?
    The affected appointments (that may be displayed incorrectly) are any single or recurring appointments that start within the affected periods.
     
  3. Could a recurring appointment beginning last year during the affected periods (using the old DST rules) be displayed incorrectly?
    Yes, recurring appointments with a start date falling within any affected periods (including previous years’ affected periods) may be displayed incorrectly. All instances of this appointment may be displayed incorrectly throughout the entire year.

    For example, an appointment starting 30 October 2006 and recurring through 2007 will appear one hour ahead for every instance of that appointment throughout the year, not just during affected periods.

    Note: This may also be a problem after the DST 2007 upgrade is installed on the BlackBerry device.
     
  4. What happens when my BlackBerry device synchronizes the Calendar with my email client? What if my BlackBerry device synchronizes with my computer calendar through BlackBerry Desktop Manager?
    In both of these scenarios, appointments and reminders for these appointments may be displayed incorrectly on the BlackBerry device if the appointments occur within the affected periods.
     
  5. What is the potential impact on calendar appointments if the DST upgrades are not applied?
    The table below shows what may occur to calendar appointments and reminders for those appointments during the affected period if you do not upgrade all components in your system.

     
    Is the BlackBerry device or computer updated with new DST rules? Is the appointment being viewed on a BlackBerry device that is updated or is not updated? How is the appointment displayed on the BlackBerry device?
    Not updated Not updated May be incorrect
    Not updated Updated 1 hour behind
    Updated Not updated 1 hour ahead
    Updated Updated Correct


    Important: For information on the impact of not upgrading, see Risks of not upgrading the BlackBerry environment.
     

  6. If my BlackBerry device has not been updated, will all of my appointments appear one hour ahead on my BlackBerry device if they start within the affected periods?
    No, appointments will only appear one hour ahead if they were created using the new time zone rules on an updated computer or BlackBerry device and are displayed on a BlackBerry device that has not been updated. Appointments that were created on a computer or a BlackBerry device that has not been updated may be displayed at the correct time on a BlackBerry device that has not been updated.
     
  7. After I update my BlackBerry device, will all of my appointments be displayed correctly if they start within the affected periods?
    No, appointments created using the old time zone rules on BlackBerry devices or computers that have not been updated will appear one hour behind in the BlackBerry Calendar. Also, appointments starting within the affected periods that were created on the BlackBerry device before the update was applied will appear one hour behind in the BlackBerry Calendar. Appointments created using the new time zone rules on updated computers and BlackBerry devices will be displayed correctly on the updated BlackBerry device.
     
  8. Is there a way to make all appointments appear correctly on my BlackBerry device?
    Yes, BlackBerry device users can manually change the times of the appointments in the BlackBerry device Calendar to reflect the correct time by recreating the appointments after the update has been installed.
     
  9. Will my appointments that do not start during the affected periods be displayed correctly?
    Yes, changes to DST dates only affect appointments starting within the affected periods.

Bottom line for IT organizations is this: This is going to be a fun upcoming March. I can't imagine what we are going to do with the already created calendars that have meetings already created prior to this patching. The potential here is a mini Y2K. When we just thought 2000 was a vague memory....! I have not seen anyone stock piling food yet but who knows!!
