Shame the clock isn't right.
It's overly optimistic.
Though while I've got your attention on the Carto Broonie... I've noticed that sometimes the X-Ray feature I've heard people talk about before will kick in without activating anything. Chunks of the game world are replaced with images of the underground, and in some instances that could be abused. :/
Not sure if thats just me or whether others have experienced similar. But its best to go by Sod's law on this one.
