Welcome to my most complex Redstone/Command block device: A fully functional 24 hour in game Digital and Analog Clock. I worked long and hard on this contraption, so please enjoy!  The time is announced hourly and the Analog clock changes redstone lamps every hour counter clockwise (oops XD). There is a video explaining my process of making this clock. Please read the following instructions to get the clock to function properly.

IMPORTANT: This clock needs a few commands to get up and ready to view. A scoreboard objective: /scoreboard objectives add TimeObjective dummy ; and in the schematic you need to type this command on top of a certain command block marked in the download:  /stats block ~ ~-1 ~ set QueryResult @p TimeObjective. These two commands are crucial to get the entire system working. 

Also be informed that the digital clock can compensate for time altering commands, but the analog cannot. I have provided buttons on the analog clock to manually reset if you decide to change the time of day. ALL of the schematic is needed because of a glitch in Minecraft causing the counter to keep counting when it should reset to 0. Once the device reaches 24000 it will reset the time back to 0.

A few suggestions to allow the analog clock to work right away: Set the time to 0, /gamerule doDaylightCycle false, and then import the schematic into your world (do it in order as I said). The clock is currently set to 6AM which is gametime equivalent to 0. After you import the schematic, /gamerule doDaylightCycle true to allow the clock to function properly. Yes the clock moves counter clockwise, but I built it that way to start so I didn't want to go and fix everything. I have a few other videos on Youtube with gameplay and other redstone devices. I will probably be uploading the Command Block testing world soon because there is a multiplayer compatible Connect four that I made.
