I think it is 9PM Eastern, but maybe 8PM. This is in the Washington DC/Baltimore area. May not be the same night or time elsewhere. Also, it may be on a cable channel and not on Big Fox. I just remember seeing it in the TV news a few weeks ago and thinking that is a good fact to tuck away in the far reaches of my cluttered brain in case I'm out some Monday night.
if you happen to remember of find out later please let me know.
