This is good for a quick prop/brick but I think it could be a bit more complex
You should get rid of the hands on the clock and make them as static shapes, then make it show the real time based on the host's computer, or make it show the time based on the day cycle.
Or there could even be clock events or something of the sorts. Hell the clock brick could probably even use print events if we want to do it that way I suppose.
I agree however, it would be really cool if the brick changed times based on the server time/daycycle time which could even be real time if need be. This is a cool prop brick its just missing some more functionality to make it really something special!!
