Re: Time and Date Synchronization - 1 hour difference

There's nothing that you can do if you must continue using the old registry.
You'd have to patch, somehow, the time zone settings in this old registry
and there are a ton of them.

I'd fix the main problem and get the time zone data fixed before deciding
that there's some other problem.

Hi Paul,

Thanks for reply!
I have installed QFEs:
WinCEPB50-061231-Product-Update-Rollup-Armv4I.msi
WinCEPB50-071231-Product-Update-Rollup-Armv4I.msi
WinCEPB50-081231-Product-Update-Rollup-Armv4I.msi
But the registry is old(last update in 2006 ),as you said this isuue may
releated the old registery.
How can I do with it?

And this is another phenomena need clarify.As the customer's request we
added a new function that is when press "OK"button in Date/Time Properties
window,the current setting date/time (GetSystemTime(&sDate);)will be
stored
in registry,so when reset the PDA can restore Date/Time . The problem is
the
reset time is one hour advanced from the the time before reset if I
checked
the checkbox(AUTO DST).
for example:
Before reset time is 2009-04-14 8:00 am, press OK to store Date/Time and
closed the Date/Time Properties window,reset the PDA,check the time is
2009-04-14 7:00 am
This problem may have the same root cause as the sync time one hour
difference isuue.

If the date/time for transitions for daylight saving time are wrong, then
you have not installed either a) the QFEs for Windows CE that have the
updated DST information, or b) the desktop updates that have the latest
DST
transition information. Since the updates for the PC happened
automatically, I'd guess that the OS that you have on your Windows CE
device
does not have the latest DST updates in it (or you're using an old
registry
from a time before the updates were made).

Hi Paul

Thank you for reply!
I checked the checkbox on *both* devices ,and the sync time still have
one
hour difference in some day.it is same as before!

Situation 1(PC DATE 2009-04-01):sync time one hour difference
checked the checkbox on *both* devices
Set PC time :GMT-08:00 Pacific Time ;2009-04-01 19:10
Set PDA time :GMT-08:00 Pacific Time ;2009-04-01 7:00 pm
Plug USB,after sync the time is:
PC: GMT-08:00 Pacific Time ;2009-04-01 19:10
PDA time :GMT-08:00 Pacific Time ;2009-04-01 8:10 pm
Unplug USB,and plug USB again,after sync the time still is:
PC: GMT-08:00 Pacific Time ;2009-04-01 19:10
PDA time :GMT-08:00 Pacific Time ;2009-04-01 8:10 pm

Situation 2(PC DATE 2009-04-10):sync time OK
checked the checkbox on *both* devices
Set PC time :GMT-08:00 Pacific Time ;2009-04-10 19:10
Set PDA time :GMT-08:00 Pacific Time ;2009-04-10 7:00 pm

PDA time :GMT-08:00 Pacific Time ;2009-04-10 7:10 pm

Is there the same problem in your device?And do you know where is the
code
releated sync time?Thank you!

No, it's not a bug. It's doing exactly what you told it to do, not
adjust
for daylight saving time. Check the checkbox on *both* devices and it
should match.

The system is Wince 5
CPU is PXA300
set the pc time zone same as PDA's time zone which have DST(such as
GMT-08:00 Pacific Time),and make sure the "Automatically adjust
clock
for
daylight saving"box be check ed in PC side,and this check box don't
be
checked in wince Date/Time control panel
Then connect PC and PDA use USB activesync ,after sync ,The time
displayed
on the PDA is one hour advanced from the host PC.
Is it a bug of Wince?
How to solve it?
