Now you've got me curious about the Treo.  The Treo seems to take its time
from the phone provider's clock.  /rich

> Daylight Savings Time Changes for PDAs
>
> In 2005, the United States congress passed the Energy Policy Act of 2005,
> which among other things extended the duration of Daylight Savings Time in
> United States, starting in 2007. Canada and Bermuda have followed suit.
>
> The problem is that, during the extended periods of three weeks in the
> spring and one week in the fall, many clocks on systems which automatically
> to change to and from Daylight Savings Time will continue to operate on
> Standard Time, even though Daylight Time is actually in effect. These
> uncorrected systems will not be synchronized with other systems which have
> been fixed.
>
> This page tells you how to correct that, so that the automatic Daylight
> Time changes take place on the correct date.
>
> We have until March 11, 2007 to fix this problem in the U.S. and Canada.

> How to fix the 2007 Daylight Time dates
>
>    1. Using Filer, check to see if file *C:\_DAT\TIMEZONE.DAT* already
>    exists. If it does, then some modification has already been made. Skip to
>    Step 3.
>    2. If *C:\_DAT\TIMEZONE.DAT* does not exist, then copy file *
>    D:\_SYS\TIMEZONE.DAT* to *C:\_DAT\TIMEZONE.DAT*. (You cannot modify
>    file *D:\_SYS\TIMEZONE.DAT* directly because it is in ROM.)
>    3. Open the Memo program, and use it to edit file *
>    C:\_DAT\TIMEZONE.DAT*.
>    4. If you have sections besides these, leave them alone. The order
>    of sections is not important. The file should look something like this when
>    you are done editing:
>
>    European
>    3:25-31  6 1:00
>    10:25-31 6 0:00
>    Northern
>    3:8-14   6 1:00
>    11:1-7   6 0:00
>    Southern
>    3:1-7    6 0:00
>    10:25-31 6 1:00
>    Mexican
>    4:1-7    6 1:00
>    10:25-31 6 0:00
>
>    5. Press *F10* to Save the file and exit Memo.
>    6. If you previously had the World Time program running, close it.
>    7. Open the World Time program, find Indianapolis IN in the list of
>    cities, and press *ENTER*. Indiana started observing Daylight
>    Savings Time in 2006. For Indianapolis, change the Daylight Savings box so
>    that Automatic and Northern are selected, and press *F10* when done.
>    Repeat this for any other cities in Indiana that you have defined.
>    8. Change all locations in Mexico so that Automatic and Mexican are
>    selected.
>
> Time Zone File FormatYou can define additional sets of Daylight Time
> changing dates yourself, in file C:\_DAT\TIMEZONE.DAT. The time zone heading
> must begin with a unique letter of the alphabet. This means you can only
> have 26 total zones defined. For instance, since there is already
> "European", you could not also have "Egyptian". It is also not a good idea
> to make the name of a zone in this file exactly the same as the name of a
> country - this will cause false hits when you use Find. This is why we use
> the name "Mexican" instead of "Mexico".
>
> The next two lines define when to change time. For instance, under
> "Northern" above:
>
>    - 3 is for March (1=January - 12=December)
>    - 8-14 is the range of dates. The 2nd occurrence of a day in a month
>    will be between the 8th and the 14th.
>    - 6 is for Sunday (0=Monday, 1=Tuesday - 6=Sunday)
>    - 1:00 means to set the clock 1:00 ahead of usual (i.e. spring
>    forward)
>
> The second line under "Northern" likewise reads, "In November, on a day
> between the 1st and the 7th, which is a Sunday, change the clock to 0:00
> later than usual ( i.e. fall back to normal)."
>
> Now that you know how to edit this, you can keep the HP 100LX and 200LX
> updated for any future changes in Daylight Time change dates.
