This is my N-th try at automating the geotagging my photos using GPS. I've tried a variety of utilities and web-based tools and found them having too many steps/clicks and don't deal with timestamps very well.
In order to batch geotag photos using GPS data, the timestamps on the camera must be matched to the GPS. Timezone is an issue here because cameras don't generally record timezones. A more minor issue is clock drift, which can often be ignored unless you're traveling at very high speed.
On the Mac OS X, GPS Photo Linker is a well written tool that supports timezone adjustment, batch stamping, and manual stamping. It looks up city/state/country information and adds those to EXIF along with lat/lon data. It also links to Google Maps so you can view the location for each of photos.
