Treo Daylight Saving Time (DST) Update

As you may know, starting in 2007, most of the United States begins a new Daylight Saving Time (DST) at 2:00 a.m. on the second Sunday in March (Spring Forward on March 11, 2007) and reverts to standard time on the first Sunday in November (Fall Back on November 4, 2007).

This is a change from the current start/end date that is built into most Palm smartphones and you will need to install a DST software update on your device to 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.

Time zone associated calendar events depend on the correct DST rule on the device and all users (see list of Palm OS and Windows Mobile devices below) should apply this update.  Third-party applications may also depend on the correct DST rule on the device.  

The devices that will require this update include:

DST for Palm OS devices
Treo 700p, 680, 650, 600, 300, 270

DST for Windows Mobile Devices
Treo 750, 700w, 700wx

According to the official Palm blog, here are some more technical details of the DST software update:

• Replaces the old DST rule with new DST rule on your smartphone or handheld. 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 started). This allows events with the DST rule change window to remain at their original times.

Additionally, it’s also worthwhile mentioning that before you install the Daylight Saving Time Update, you may need to install two Microsoft DST updates in order for the system on your PC to reflect the DST rule changes.
