The boost time zone data base and the tzinfo generated shapefile aren't completely in sync. Unfortuneately, I don't think there is an obvious fix. Boost doesn't make a spatial file, and the available shapefile is based on tzinfo. Generating a boost compatible csv from the tzinfo data seems like a possible alternative. This stems from #25 where the zone from the map had an 'extra' 'Argentina' in the name, and the boost spec did not.
