Yes. Although my question was not really "what zones can be merged" (I already solved that -- I can already identify zones which have identical rules for "present and future times"). The real question was: whenever I find two zones that can be merged, which one wins? For example, in the case I mentioned in my original email (Spain), Ceuta should be discarded and Madrid should be kept. Thanks, Guillermo Rodriguez Garcia [email protected]
