Due to a bug, Palm's Treo 700w (the Windows Mobile edition of the popular smartphone), will have trouble fulfilling this task, as some calendar appointments may not spring ahead by an hour tomorrow.

A Palm support page says:

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 early. For example, if you had scheduled a dental appointment for 9:00 a.m. Monday, it would appear on your smartphone as 8:00 a.m. Monday; it will also appear incorrectly in Outlook on your desktop PC as 8:00 a.m. Monday.

In Addition, full-day appointments may appear one day early.

TreoCentral reports the bug appears to affect only entries made on the Treo itself and not those created on the desktop and then synced to the smartphone. But there's no way to tell the difference between the two different type of appointments.

Palm says the issue is under investigation by its engineers, who are attempting to create a fix. In the meantime, the company has a support page with a couple of workarounds, neither of which will seem particularly attractive to users.

Method One (Preferred Method): To correctly display the appointments that still appear one hour early, delete those appointments in Outlook and on your smartphone, and re-create them in Outlook.

Method Two (Alternate): If you'd rather not delete events, and if you'd like to be able to create events on your smartphone, you can turn off Network Time and manually correct the times of your appointments.

See Palm's support page for step-by-step directions and additional information on the workarounds. The daylight savings bug is only with the Windows Mobile-based Treo 700w and does not affect the Palm OS Treo 600 and Treo 650.
