[ietf-caldav] Problem with REPORT query

[Pascal Robert <[e-mail]>]

Hi,

I'm trying to use a calendar as a timeline to display stuff on large  
screens, so I'm adding events with reccurences every XX minutes, and  
each event have a 30s duration. Event creation works fine, but when I  
try to query available events for a specific time range, I get events  
who are outside the range.

Server is Zimbra Collaboration Suite 5.09. Am I doing something wrong?  
I looked at the RFC for CalDAV and it seems fine. This problem only  
happens for reccurrences, for one-time event it's working fine.

REPORT /dav/mtmls134/Calendar/ HTTP/1.1
...
<x1:calendar-query xmlns:x1="urn:ietf:params:xml:ns:caldav">
<x0:prop xmlns:x0="DAV:">
<x0:getetag/>
<x1:calendar-data/>
</x0:prop>
<x1:filter>
<x1:comp-filter name="VCALENDAR">
<x1:comp-filter name="VEVENT">
<x1:time-range end="20090114T211125Z" start="20090114T211025Z"/>
</x1:comp-filter>
</x1:comp-filter>
</x1:filter>
</x1:calendar-query>

And the answer contains occurences instances who are outside this  
range :
