You mean you want to set it up so it downloads between [xx:xx] and [xx:xx]? Hmmm... I personally used quite a few BitTorrent clients and never saw one that could do this...

What you CAN do however is have your computer open the client at [xx:xx] and close it at [xx:xx] but then you won't be able to download the small files either... unless you use two clients (one for big files and one for small ones)

Other then that i doubt you'd find one that does it itself... I had the same problem with my ISP at first but i just did it manually :/
