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. Hope this helps, -- Gregory (Greg) L. Snow Ph.D. Statistical Data Center Intermountain Healthcare greg.snow at imail.org 801.408.8111

Subject: [R-sig-Geo] lat/lon to timezone
Dear geo users,
pardon this trivial question (I did not succeed in searching the
archives):
is there an R function in one of the many spatial packages which
returns the
time zone for a given lat/lon pair ?
Thanks !
Markus
