Palm has posted updates for both Palm OS and Windows Mobile devices to add compatibility with the new Daylight Saving Time changes. Beginning in 2007, Daylight Saving Time starts on the second Sunday in March (March 11, 2007), and changes back to standard time on the first Sunday in November (November 4, 2007).

Palm devices, both smartphones and handhelds, need to be updated so that they reflect the correct time when the new DST changes take effect. Without the Daylight Saving Time Updates, calendar events and email messages will indicate an hour off the actual time in locations that observe DST.
