Does anyone remember a children's television series from the early 90s which centred around a clock, in the shape of a man (IIRC dressed in mask, top hat and tails, or similar) that was based in a shopping mall? Children would use it to, presumably, save the world by time travelling - I can't remember - and were aided by a young woman. The whole show may have been Australian, I'm not sure - it was around the same time as a lot of kids TV shows that came over from there, like The Girl From Tomorrow and Ship To Shore.
