Meetings created in ZWC and most external systems define the time zone, for example:

DTSTART;TZID="(GMT-06.00) Central Time (US & Canada)":20080229T100000

Zimbra Connector for Outlook v5.0.2 with Outlook 2007 uses the time zone in the DESCRIPTION, but the DTSTART/DTEND attributes are in GMT:

DESCRIPTION:When: Friday\, March 14\, 2008 1:30 PM-3:30 PM (GMT-06:00) Central Time (US & Canada).

The detail view in the ZWC Standard HTML renderer (only) displays the appointment time incorrectly. See Bug 25229 - Appointment detail view in HTML client (only) uses wrong time zone. Note in the picture at that the "Fax Server Group" time is correct in the day view and in the appointment body, but is wrong in the individual item's Date: header. The ZWC HTML rendering bug is triggered by any invite created by ZCO and affects the Standard HTML client, the XHTML iPhone client, and the /home/user/Calendar.html view.


1) ZCO should set a time zone for DTSTART/DTEND, not just DESCRIPTION.

2) Fix for the bug in the HTML renderer.
