You've probably figured out your problem by now, but for anyone else that might be trying to do this, I finally got it working. The biggest problem I had was getting the date and time formats correct, and also figuring out that choosing a type of 'single' meant that you couldn't set the time (single is apparently just for all-day events).

Here's the code I have for inserting a calendar entry:

function addEvent($date, $title, $info, $userid) {
    global $vbulletin;

    $eventdata = new vB_DataManager_Event($vbulletin, ERRTYPE_STANDARD);
    
    $timeStamp = strtotime($date);
    // I think I should use vbdate here, but until I figure that out, I'm
    // doing it myself
    $fromTime = array(
        'defined' => date('g_i_A', $timeStamp)
        );
    $toTime = $fromTime;
    $fromDate = array(
        'month' => date('m', $timeStamp),
        'day' => date('d', $timeStamp),
        'year' => date('Y', $timeStamp)
        );
    $toDate = $fromDate;
    
    // note you don't want 'single' unless it's an all-day event
    $eventdata->set_info('type', '');
    $eventdata->set_info('recur', 0);
        
    $eventdata->setr_info('fromtime', $fromTime);
    $eventdata->setr_info('totime', $toTime);
    $eventdata->setr_info('fromdate', $fromDate);
    $eventdata->setr_info('todate', $toDate);

    
    $eventdata->set('title', $title);
    $eventdata->set('event', $info);
    $eventdata->set('allowsmilies', false);
    $eventdata->set('utc', -8);
    $eventdata->set('recurring', 0);
    $eventdata->set('calendarid', BAUE_CALENDAR_ID);
    $eventdata->set('dst', 1);
    
    $eventdata->set('visible', 1);
    $eventdata->set('userid', $userid);

    $userfields = array();
    $eventdata->set_userfields($userfields);
    
    // error checks
    $eventdata->pre_save();
    if (!empty($eventdata->errors)) {
        echo $eventdata->errors;
    } else {
        echo "Success <br>\n";
    }

    $eventid = $eventdata->save();  
    

}
