Beginning in 2007, Daylight Saving Time begins on the second Sunday in March, and changes back to standard time on the first Sunday in November. This is a change from the start/end date that is built into older Palm devices.

Update your device to reflect the correct time when the DST rules take effect. Without the Daylight Saving Time Update, calendar events and email messages may indicate an hour off the actual time in locations that observe DST.

Time zone associated calendar events depend on the correct DST rule on the device and all users should apply this update. Third-party applications may also depend on the correct DST rule on the device.

Outside the United States?

Users in all other countries should download and install this update. Meetings that are scheduled or received with participants in the United States may require the update to ensure that calendar events display properly. Also, when traveling in the United States, this update should be installed to ensure the proper DST rules are set on the device.

What does this update do?

Replaces the old DST rule with new DST rule on your device. Then it notifies the Date & Time application that DST rule change occurred.
Replaces the old DST rule embedded in any Calendar events that occur after March 11, 2007 (when the DST change begins). This allows events within the DST rule change window to remain at their original times.

First: Update Windows and Exchange Server

Before you install the Daylight Saving Time Update, you may need to install two Microsoft updates in order for your system to reflect the DST rule changes.

Contact your organization's IT department before installing these Microsoft updates. If you have any questions about the updates, consult with Microsoft or your IT department. These updates are not affiliated with Palm.
