It CAN use the archive bit if its configured to (at least one of the clients I installed recently had that option in a 5.3.5 client), but most folks do not turn that on. I'm talking a Windows client that is.
Now, exactly how it determines a file has changed, I'm not exactly sure about but I think it uses a combination of size, date modified time stamp, and something like a CRC check. I just can't remember all of it right now.
