I modified the Arduino code from this thing:
http://www.thingiverse.com/thing:570797
It was modified to use the 28BYJ-48 stepper motor and ULN2003 drive module. The picture shows a Arduino Pro Mini and a bread board with the drive module. Any Arduino will work.(UNO, Nano, Mega, Pro Mini, etc.) There is also a switch which is used to "set" the clock. Each press is one minute.
I made the standoff's using this thing:

I had to adjust the X and Y dimensions by .2 each to fit the gears loosely.
Put the minute and hour gears on with them set at 12 o'clock position. (facing each other)
