The SPA9000 will not be able to differentiate between the two copies of "start" and "end" parameters. Have you tried putting an "OR" separator between the two time range sets?
i.e. "start=9:30:0;end=13:30:0|start=15:0:0;end=19:0:0"
I don't have a spare SPA9000 to try this for you, and I've not seen any documentation that indicates whether or not the day time field supports more than a single time range, so please let us know if it works!!!
