如何通过fql获取朋友事件（或基本上不是由我创建的任何事件）的正确UTC开始日期

I'm trying to get the correct start date for events that were not created by me. I understood how facebook saves events starting and ending date ( Can someone expalin me how facebook stores the start and end time of events?) and i understood that i need to know my timezone to get the correct starting date in UTC, but what about other events?How do i get the timezone of the user who created the event using fql or the graph api?Is there a way? I'm using the php SDK.
This is the code i use to get events

            $fql = "SELECT 
                        eid,
                        name,
                        description,
                        start_time,
                        end_time,
                        venue,
                        location,
                        update_time
                    FROM
                        event
                    WHERE 
                        eid IN (SELECT eid FROM event_member WHERE uid = $id)" ;
            $events = $facebook->api( array(
                'method' => 'fql.query',
                'query' => $fql,
            ) );

Timezone seems to be restricted to the current user only.

However, you should be able to get the owner->id of the event. If the owner is a user (person) then you can get the location->id which may yield a lat\long from the place or the location->name. In either case you still need to do a look up on the location to match it to a timezone.

Also, the location information might not be available unless your access token has friends_location permissions.
