Clocks will be "springing forward" a few weeks earlier this year thanks to the Energy Policy Act of 2005. Starting in 2007, most of the United States and Canada will observe Daylight Savings Time from the second Sunday in March to the first Sunday in November. This poses a problem for computers, as they are expecting to adjust their clocks in April and October. Companies are putting out updates so that their operating systems will move their clocks forward and backward on the correct dates.
Palm has issued a Daylight Saving Time Updater for it's Palm OS and Windows Mobile handhelds and smartphones. In a classroom full of handhelds, I suggest syncing the DSTUpdater.prc file to one handheld. and beaming it around to all of the other handhelds. Once launched, it's a very quick install. Note: If an updated handheld is hard reset, then the DSTUpdater will need to be installed and run again. This will probably need to be done each fall after handhelds are reset for the new school year.
If you don't update your system for the new Daylight Savings Time rules, it's not the end of the world. You can always manually adjust your computer's clock. Unfortunately, that will involve adjusting your clock up to four times a year. You can manually change the time in March and November and your computer may make annoying changes in April and October (following the old rules).
Despite the confusion it causes, Daylight Saving Time is a great topic for students to explore various science and social studies concepts. Investigating Daylight is a great lesson plan from Microsoft and Daylight Savings Time from WebExhibits is a great resource for students.
