OL97: Schedule+ and Outlook Appointments Differ by One Hour

ID: Q175695

The information in this article applies to:

• Microsoft Schedule+ for Windows, version 7.0, 7.5
• Microsoft Outlook 97

SYMPTOMS

Appointments scheduled between the thirty-ninth and forty-third weeks of the year, between Microsoft Schedule+ 7.x users and Microsoft Outlook 97 users, may be off by one hour, even if both users are in the same time zone.

If a Schedule+ user initiates an appointment with an Outlook user at this time of year, the Outlook user's appointment may be scheduled one hour late. For example, if the Schedule+ user requests a meeting with the Outlook user at 2:00 PM, the meeting appears on the Outlook user's calendar as 3:00 PM.

If an Outlook user initiates an appointment at this time of year with a Schedule+ user, the Schedule+ user's appointment may be scheduled one hour early. For example, if the Outlook user requests a meeting with the Schedule+ user at 2:00 PM, the meeting appears on the Schedule+ user's calendar as 1:00 PM.

CAUSE

This problem is caused by the way the two programs handle daylight saving time. Outlook uses the operating system's time zone information while Schedule+ uses its own internal, time zone information.

NOTE: This problem is experienced when using the Microsoft Windows NT operating system, version 4.0.

WORKAROUND

To work around this problem, include the correct meeting time in the subject field of the meeting request message.

STATUS

Microsoft has confirmed this to be a problem with Schedule+ version 7.x. We are researching the problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

With Outlook (using the operating system's time zone data), daylight savings time changes the first Sunday after the forty-third week of the year. With Schedule+ (using its own internal time zone data), daylight savings time ends the first Sunday after the thirty-ninth week of the year. This accounts for the discrepancy between the thirty-ninth and forty-third weeks of the year.
