Procedure to duplicate the bug:

FROM a computer currently in a time zone that changes between daylight and standard time, create a meeting on a date that is in daylight time. Invite someone. I don't think it matters what time zone they are in.

From the invitee's Outlook (or OWA), view the email containing the invitation. The description of the timezone listed there is incorrect.

What SHOULD be displayed, for example, if the meeting was scheduled in Texas, is for the timezone to display as Central Daylight Time (UTC - 05:00), or something along those lines. What is actually displayed is Central Standard Time (UTC - 06:00).

The actual times seem to be processed correctly. This is just a display problem. Nevertheless, the display problem makes doing the time zone math for the invitee impossible. If the time is translated assuming it was made in CST, as stated, the wrong math results.

Probably what is happening is that the standard time zone description field is used in all cases for display, instead of displaying the daylight time description for events that take place during daylight time.

I note that the google calendar does not have this issue. The very same invitation sent to an Outlook recipient and a google calendar recipient will display Central Daylight Time (UTC-05:00) for the google user and Central Standard Time (UTC-06:00) for the Outlook user.

This seems to affect OWA, Outlook for Mac, and Outlook for Windows.
