I'm retrieving calendar events for specific months using the Zend PHP API. This seems to work OK in most cases, but when I attempt to retrieve events for the current month in my default calendar, the feed only appears to contain events between 11th and 31st July - any events prior to the 11th do not appear. The problem appears to be specific to the current month and the default calendar. I get all the expected results returned if I query for different months on the default calendar, and queries work OK for any month when using my other calendars. Any suggestions appreciated. Ken
