Check future events

Hi,

If I have an event object like this
$EM_Event = em_get_event($post->ID, ‘post_id’);

Let me know how to check whether this event is a future event or not by using pure php code.
I saw the conditional place holder {is_future}content{/is_future}, but in my case I need to put a condition in a php code, like below.

if($EM_Event is future){
…..
….here my codes …..
.. ..
}

Thanks,
Chathuranga.
