WORLD TIME

World Time can automatically adjust system clock for Daylight Savings time

95LX 100LX

When you add a new city like Fairfield, Iowa to your cities list, you can set up your 100LX to automatically adjust the system clock when daylight savings time changes. (The built-in cities are preconfigured.) Go into World Time, highlight the city of your choice and press (ENTER). You'll get a screen that looks something like this:

City Data Screen in WorldTime: Graphic

Press (<Tab>) until the cursor is in the Daylight Savings box. Press any of the arrow keys until Automatic is highlighted and press (ENTER). Then press (<UpArrow>) or (<DownArrow>) to select the DST schedule of your choice.

Northern: First Sunday in April to last Sunday in October, Used in most of North America.
Southern: Last Sunday in October to first Sunday in March, used in most of the southern hemisphere.
European: Last Sunday in March to last Sunday in September
None: No Daylight Savings Time.

When you're finished, press (F10).

When the time comes to change DST, World Time will pop up and ask whether you want to update the system clock. Answer OK and your system clock is adjusted. (For more, see HP 100LX User's Guide, page 14-10.)

I ran into a problem because I went into SET UP and set the time back on Saturday evening, forgetting that I had configured my 100LX to do so automatically. When I next used my Palmtop on Monday I got a message on the screen that "Daylight savings time has changed. Update the system clock?" I mistakenly pressed (ENTER) and set the time back another hour. I had to go back into the SET UP function and reset the system clock.

HP 95LX

The HP 95LX does not automatically adjust for changes in DST. You must go into Appointment Book, press (F9) (Watch), go to the Local or World city and press (F6) (DST) and answer Yes to toggle back and forth one hour. (For more, see the HP 95LX User's Guide, page 17-46.)
