Analog clocks have always annoyed me, so I decided to make my own. This is the logical solution I think. There's only one hand, which moves round once a day and shows where the sun is on the map. In the photo it is nearly 10pm in the UK so the sun is over the Alaska timezone. The 6am-6pm line is your horizon, so the top half is your daytime.
This one is for GMT/UTC - you'd need to rotate the map for different timezones, to put your location at the top under the noon marker.
Is it really proper to call it an "analog" clock? That word makes me think electronics, just not digital electronics. Maybe "mechanical" would be more appropriate.
That said, very nice clock! It never occurred to me that you could indicate the Sun's position that way.

The map is an azimuthal equal-area projection, made with NASA's G.Projector: http://www.giss.nasa.gov/tools/gprojector/
I bought a 24-hour clock and simply inserted the printed map in place, after removing the minute and second hands.
Make your own!
