XWEB: CDO Does Incorrect Time Zone Correction for Paris, Madrid, Amsterdam

ID: Q196200

The information in this article applies to:

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 TimeZone 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.
