Hello everybody Entombed here saw a similar build and decided i could compact it down and extend the 30-Min Time Limit that it had.

Clock is based off of a Dispenser clock that dispenses items onto a pressure plate that then despawn in 5-Min has a total of 8 Dispensers totaling up to a 45-min clock it is capable of being connected to whatever you desire.

Have fun and I hope you enjoy my Animated Timer.
