I'm using XP-SP2, Outlook 2002 client based, linux mail server.

I have applied my OS DST change, WindowsXP-KB931836-x86-ENU.exe, Outlook
calendar tzmove.exe patch and my linux OS patch.

When I receive emails from Outlook, the time stamp is 1 hour ahead of the OS
time. This does not affect when I use the webmail, linux based. But when I
send myself test mails from any webmails, Outlook adds another hour to it.

I’ve already check the Calendar Options Time zones, Tools --Options --
Calendar Options -- Time zone, and it is pointing to my correct zone; EST
with Adjust DST.

HOWEVER, the current time shown below it is 1 hour ahead. If I uncheck the
DST there , it affects the OS time by moving it 1 hour behind of actual time.

For example, OS time 10:00AM EST w/DST, in Outlook Time Zone it is 11:00AM
although it's EST w/DST too. What gives?

I even did the manual update, TZedit.exe, and it is setup to correct
setting; 2nd March @2AM, 1st Nov @2AM, DST +1 hr.

Rebooted the Outlook, OS, and issue still exist.

I checked Microsoft, and all I found is relating to the tzmove.exe update;
which only talks about the Calendar moving tasks, etc.

Your help is greatly appreciated.
