 This involves getting the `local_info` structure from the `time_zone` for that `local_time`.  The `local_info` will have all of the information about that `time_zone/local_time` combination, including whether there is a unique mapping to UTC, a non-existing mapping (as in the gap created by "spring forward"), or an ambiguous mapping (created by a local time occurring twice during a "fall back").
