[R-sig-Geo] lat/lon to timezone

> I found a shapefile for a timezone map at http://openmap.bbn.com/data/shape/timezone/, you can load this in using maptools and related packages, then use any of the tools to find out which polygon your lat/long pair is in (doesn't work in the oceans, etc.) and look at its timezone data.

 I just tried opening that up in Qgis, and when I queried a couple of
the big regions of Canada Qgis didn't think I was clicking on
anything, despite them being shaded properly.

 A data error problem? Or maybe nobody in that area of Canada has a watch...
