Hasan,
JFBConnect doesn't have any ability to push articles to Facebook. We've never implemented an auto-pushing feature for this specific reason.. it causes more problems than it's worth and doesn't help you to brand your site well or target the right audience.
So, if content is being automatically published to Facebook, it's coming from another extension. You'll need to contact those developers of that extension to determine their scheduling possibilites.
Hope that helps,
Alex
time-scheduling possible?
