If Daylight Savings Time caused you all sorts of calendar and appointment grief, it might not be you but your Treo 700w. After Daylight Saving Time begins (2:00 a.m., first Sunday in April), you may notice that some appointments in your smartphone’s Calendar appear one hour late. For example, if you had scheduled a dental appointment for 9:00 a.m. Monday, it would appear on your smartphone as 10:00 a.m. Monday; the same appointment will also appear incorrectly in Outlook on your desktop PC as 10:00 a.m. Monday. In addition, full-day appointments may appear one day late.
The ‘More information’ link will take you to Palm to explain how to resolve the issue. A long term fix remains under investigation by Palm engineers.
