The Ancient Clock is a special moving clock item that can only be obtained by following specific steps. It is locked inside the Ancient Treasure Chest, and is used to work the Time-Machine (WIP). It is somewhat similar to the Ancient Key. It is the second item in the mod with a moving texture, the first being the Dominican Amber.
It was added in the 7.2 'Ancient Kings' Build.
It is a strange golden clock that has several rings around it. When held, does not tell the proper time.
Step one, find a mysterious sarcophagus and place a scarab gem in its chest. This will release Anu. After you have defeated him he will be laying on the ground with smoke coming off of his chest and an ancient key next to him. Grab the key and right click on Anu, it will take you to a strange room with an ancient chest and a portal. Right click the chest with the ancient key and you will get an ancient clock.
Place into a Time Machine. It will load up a timer, until the gui shows up.
