In the meanwhile, have a look at this (pretty) map showing all the timezones: http://maps.derickrethans.nl/?l=timezones&lat=50&lon=20&zoom=3 (Built with Eric Muller's shapefiles fromhttp://www.efele.net/maps/tz/world/)
Nice use of OSM ... Next step would be a nice link to data on a timezone;) I've been looking into that for another couple of jobs, but it's well down the todo list. I do have that too, I'm just still fixing up the demo online a little to add more information: http://maps.derickrethans.nl/?l=timezones,timezone&lat=38.60&lon=-86.90&zoom...
Would you like to see anything added there?
The 'wish list' from my end is to have a selectable overlay on OSM which gives historic information. So click on a timezone and go to a page which details the calendar back through time so we can cross check genealogical data. I've got a crude database driven site but it needs a lot more work on the calendar variations. At some point, clicking on the TZID on your pop-up would link to that type of data. More of a problem is mapping changes in boundaries ... not a lot have changed since daylight saving was introduced, but it's something that the historic OSM should be able to handle. -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk
