Can you rotate part of a linked object?

Sorry if this is a silly question but I'm new here and a bit stumped.

I've made two objects, one is a base, another is a cube that floats above it and rotates to display the digits of the time on different faces.

I'd like to link these together to make a single object but when I try it I either get nothing rotating or the whole lot rotates. I'd assumed that the script I have to do the rotation would only be applied to the object it belonged to.

Have I missed something obvious? Can this be done?

Thanks,

Ame

The script you have does only do the rotation to the object it belongs to, but when you link the 2 prims together they become one object.

I believe this thread had the answers you need

Thanks, that does indeed cause only one object to spin. My next problem is how to control it so that I can stop the rotation when the right face comes up and set up the next rotation.

I tried using at_rot_target events but I couldn't get it to work. Maybe I'm confused about the different coordinates of parent and child or maybe just doing something wrong. I'm also worried about the possibility of cumulative errors with rotation targets that could build up over time.
