Q196200: XWEB: CDO Does Incorrect Time Zone Correction

Article: Q196200
Product(s): Microsoft Exchange
Version(s): WINDOWS:5.5
Operating System(s): 
Keyword(s): exc55 EXC55SP3Fix
Last Modified: 30-SEP-1999

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Outlook Web Access, version 5.5 
- Microsoft Exchange Server, version 5.5 
-------------------------------------------------------------------------------


SYMPTOMS
========

For dates falling between the last Sunday in September and the last Sunday in
October, when you use a browser to access an Exchange Server 5.5 computer with
Outlook Web Access (OWA) Service Pack 1 (SP1), if the Time Zone setting on this
browser is the Paris, Madrid, or Amsterdam option, a new appointment created in
the Calendar will appear one hour later than when viewed with the Outlook 98
client.

CAUSE
=====

In 1996, the European Union (EU) standardized a EU-wide "summertime period." The
EU version of Daylight Saving Time runs from the last Sunday in March through
the last Sunday in October.

This change was not taken into account by the CDO libraries.

RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Exchange Server
version 5.5. For additional information, please see the following article in the
Microsoft Knowledge Base:
