XCLN: Schedule+ Appointments Scheduled Time Incorrect

Appointments between Schedule+ 1.0 users and Schedule+ 7.0 users are scheduled incorrectly if the time the appointment was scheduled occurs before daylight saving time and the time of the appointment occurs after daylight saving time.

For example, if the current date is October 15, 1996 (and daylight savings time occurs on October 27, 1996), and you send a meeting request for November 5, 1996, at 12:00 PM from Microsoft Mail using Schedule+ 1.0 to a Microsoft Exchange user using Schedule+ 7.0 and the Microsoft Exchange user accepts the request, the meeting is scheduled for 11:00 AM.

In contrast, if the current date is October 15, 1996, and you send a meeting request for October 16, 1996, at 12:00 PM from Microsoft Mail using Schedule+ 1.0 to a Microsoft Exchange user using Schedule+ 7.0, and the Exchange user accepts the request, the meeting is scheduled for 12:00 PM.

This problem occurs when the meeting request is sent by the Schedule+ 1.0 user to the Schedule+ 7.0 user, and vice versa. Schedule+ 1.0 is not aware of time zones or daylight saving time.

NOTE: When you send a meeting request between two Schedule+ 1.0 clients across time zones the meeting times show the time the message was scheduled by the requester. There is no adjustment for time zone differences.

Schedule+ 7.0 is aware of time zones and daylight saving time. When you send mail between two Schedule+ 7.0 clients (assuming each user has properly set their time zone and clock in Schedule+), across time zones or daylight saving time, the meetings times are correct for both clients.

Microsoft has confirmed this to be a problem in the products listed at the beginning of this article. This problem was corrected in Microsoft Exchange Server 4.0 U.S. Service Pack 4. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

If message conversion is being handled by the client, and the customer is using Schedule+ 7.0 and the Microsoft Mail Service Provider to get to a Microsoft Mail Post Office, the problem can still occur.

If you are using Microsoft Mail and you use Schedule+ 7.0 to send a message, the message is converted on your computer. When the recipient receives the message, it is converted on the recipient's machine unless the Schedule+ 7.0 properties are already in the message.

If you are using Microsoft Exchange and Schedule+ 7.0, if you send mail to a Microsoft Mail user, the Microsoft Mail Connector Interchange (MSMI) does the conversion.

Basically, the message content is converted at the first Microsoft Exchange gateway (MSMI, IMC, and so forth). No process exists to override any previous conversion, so the conversion only happens once.
