Analog Clock

This is an analog clock that will fit in a building and can run in real time or at a minecraft time rate. It has an hour chime.

The schematic has an 13x11 block footprint and is 20 blocks tall. There are buttons on front to adjust the hour or minute hand position. The back has a lever to choose realtime or minecraft time, and a button to start the minecraft time timer if it gets stuck.

This will easily fit in a building or tower and is readable as a normal clock. The diamond block represents the end of the hour hand with the gold block represents the end of the minute hand. The minute hand moves every 5 minutes in real time mode, and in minecraft time mode it moves every 4.166 seconds. There is a clever circuit to get this fractional tick rate accuracy over a period of time by using a 4.1 second delay followed by two sets of 4.2 second delays.
