I've manage to use this solution:
firstcheck=datetime.fromtimestamp(float(request.args(1)))
session.id=session.id or {}
if not post_id in session.id:
session.id[post_id]=firstcheck
lastcheck=str(session.id[post_id])
if str(firstcheck)<lastcheck:
firstcheck=lastcheck
and then query the db for posts created after > firstcheck
if returns any results:
session.id[post_id]=str(request.now)
