If you've got an HP iPAQ and need to apply the DST update, use the HP iPAQ Daylight Saving Time Fix on the HP web site, not the one for Windows Mobile on the Microsoft web site. You do want to follow the instructions on the Windows Mobile page for your OS and for Outlook, but when you get to the part where it says to download their update, download and apply the HP update instead. It works as advertised - I tested it by changing the clock to 3/11 at 1:59 a.m. and at 2 a.m. it changed to 3 a.m.
