Recently I come cross this wired issue with Outlook 2003. When I sent an email to someone it actually shows a wrong sent time. It affect badly when you try to send a new appointment. It will go with wrong timing. Computer time, Computer time zone, email server time is correct. Email receive time is correct as well. Where is the problem? How to fix it? Fix is quite simple. This occurs simply because you have unchecked the "Automatically adjust clock for daylight saving changes".
Double click on the computer clock (task bar) and go to "Time Zone" tab and check the "Automatically adjust clock for daylight saving changes" check box and click "Apply" and then "OK". This will fix the issue. It is always better to give a restart to your computer and outlook2003.
