i got answer stack on flow post
filtering facebook users profile feeds updated_time

it's possible using fql.

for example, modifying example on facebook developers site, can retrieve current user's posts wall/feed updated before december 30, 2009 @ 12am est so:

select post_id, actor_id, target_id, message stream source_id = me()  , updated_time < 1262196000 limit 50

to knowledge can't filter updated_time using graph api.
