Sounds like you'll have to do this twice a year! The procedure is pretty simple actually (after you turn on the device!).. (1) Tap the bottom tab (2) Tap the tool image (setup menu) (3) Select the clock image (Time zone and date) (4) From here you can edit the highlighted items (Day, Month, Year, Hours, Minutes) by tapping the up or down arrows! (5) To apply the new setting, tap the "OK" button You can even specify your home and travel time zones by following the instructions on page 149 of the user manual! Hope that helps!
