There isn't an easy way to do it. Calibre does not support the notion of change triggers on custom columns, and the template language does not support assignment to fields. Something like the coloring rules as triggers is imaginable, but it would not be particularly easy to do. I would be particularly concerned about ordering and circularity.
Beyond getting into calibre's code and hacking it to implement the trigger, I think the only way to accomplish this is to write a plugin that manages the boolean column. Instead of setting the bool column directly you would talk to the plugin using keyboard shortcuts. The plugin would change the value of the bool column, and if appropriate set the value of the date column.
