After you configure the Jerusalem time zone settings to match the transition dates for daylight saving time, meetings are moved ahead by one hour when a user accepts a meeting request by using a CDO program in Exchange Server 2003 (916989)



The information in this article applies to:

  • Microsoft Exchange Server 2003 Enterprise Edition
  • Microsoft Exchange Server 2003 Standard Edition

SYMPTOMS

Consider the following scenario. You use the TZEdit tool to customize the Jerusalem (GMT + 02:00) time zone settings in an organization that is running Microsoft Exchange Server 2003. You configure the time zone settings to match the official transition dates for daylight saving time that were announced for 2006. You send a meeting request to a user in the organization. Then, the user uses a CDO program, such as the Auto Accept agent or Microsoft Outlook Web Access, to accept the meeting request. In this scenario, the time of the meeting is moved ahead by 1 hour. This problem occurs when the meeting is scheduled between the following dates:
  • Between March 26 and March 31, 2006
  • Between October 1 and October 29, 2006

CAUSE

This problem occurs because the CDO time zone tables differ from the Microsoft Windows time zone tables. Therefore, the daylight saving time transition dates are not correctly resolved.

RESOLUTION

Hotfix installation information

After you install the hotfix, the daylight saving time transition dates are correctly resolved for the Jerusalem time zone for the year 2006. Additionally, the start date of daylight saving time is also resolved for several years. However, because the end date of daylight saving time is not based on the Gregorian calendar, this problem is not resolved in the years following 2006. The following table lists the dates that CDO programs will correctly interpret as daylight saving time transition dates after you apply this hotfix.

MORE INFORMATION

In 2005, Israel amended the law that affects the dates for daylight saving time. Now daylight saving time will start on the last Friday before April 2 at 02:00 A.M. Daylight saving time will end on the Sunday before the tenth day of the Jewish month of Tishrei, at 02:00 A.M. This decision causes the transition dates for daylight saving time to occur on the following dates.
