The tz_antarctica shapefile (zip, sha1) captures the TZ timezones of Antarctica.

Unlike our other TZ maps, this map is made only of points. There is one point for each permanent base listed at, at the coordinates given on that page. Each point is also labeled with the name of the base (in the station field), as well as the TZ timezone used at the base or the value unknown if TZ has no indication.

Construction of the shapefile

The ingredients (zip, sha1) contain a script to build the map.
