I'm facebook graph API user.
Recently found that since parameter works weird.
I'm using that to find all upcoming events and filter out past events for a particular venue.
For instance: When I use query like this
/v2.5/481931581856759/events?access_token=&limit=5
I getting all events.
But if I add since variable, some events are missing
/v2.5/481931581856759/events?access_token=&limit=5&since=1471468270
In this case can not find an event with start_time "2016-10-28T19:00:00-0700".
Why that happens or I misunderstand something?
