90's kids TV show with a shopping mall clock that involved time travel and a glass ball?!??

Does anyone remember a kids TV prog that sounds like the above from the 1990’s, possibly on Channel 4?? It was from Australian/New Zealand? There was a shopping mall with some weird clock thing that had a dummy person in a 30s gangster suit…. The clock thing was a time machine that sent you to the future which was some desert with tents and the future people wore orange overalls. There was also a magic glass ball too that got lost or something and the main person in it was freakin out cause she had to get it back…… Does ANYONE remember this?!??
