Is this it? I can't remember much about this game but, just activated a different scenario in this room and this was the result. Still don't think it's what you're reffering to though...
Does anyone know where this scene is from or how to activate it normally?
Figured it out lol!

I wish I remembered more about this game, would be much easier knowing what I'm looking at... Got no idea about Barry stopping in front of the clock like you say; someone mentioned there was a video? Have you got a link to it? I know what the room flags do in this room now and none of them seem to indicate any interaction between Barry and the clock, tried all the things I could (so far) to force it out and I'm pretty confident there's nothing there. Seems a very unique thing indeed...
