how do i build a digital clock in multisim

[ebell211]

I need help. I am trying to build a digital clock in multisim. I know some things but not what I need to know. Originally this project was supposed to be a full 12 hour format with minutes and seconds but  the instructor decided to make it just the hours. So, count to 12 then reset to 1. I want to use jk flip flops, 7447 decoder and 2 seven segments. I am attaching the circuit that my instructor helped me with yesterday that counts from 3-9( I dont know why , but just in case it helps). Also, I am not looking for someone to just build a circuit for me, I want to understand HOW it works. From what I was able to understand yesterday, it seems that the output is derived from the combination of my clears and presets, but I couldn't figure out exactly what my instructor was trying to explain to me. PLEASE HELP!!!!, this project is due in 6 days and I need ti understand it.

Hello,

For those of you are still interested in knowing how to build a digital clock in Multisim, you can find a digital clock in the component database under The Sources group, Digital_Sources family.  After placing the digital clock on your schematic you can change its frequency, duty cycle, and delay time in its property window (you can access by double-clicking on the component).
