Wonko: What is the main script, and where does it draw the custom clock? I would prefer not to use a refresh rate variable, as that would result in a clock being drawn, say, 30 times a second. The animation, however, would only go for maybe half that time - so I would only need the first 15 redraws, the rest would just be wasting processor. Also, for a clock that doesn't show seconds, the benefit of redrawing a fixed number of times in a loop is huge: 15 redraws per minute (all in the first half-second) vs. 1800 redraws per minute. This is why I would like to find out where I can explicitly ask for a redraw, instead of just letting the main clock script give me one.
