It's marking the time 'bin' it entered the queue as queued and marking the 'bin' it started running as running, Also markes the 'bin' it stopped running as running if its not the same 'bin' as the one it started running in.

I read the problem differently. Do you want the number of jobs that are still waiting in the queue (at the end of the time slot) and the number of jobs that haven't finished yet (also at the end of the time slot)?
