Hello all, Not sure if this is the best place to ask this (and if not, I would be very thankful for any suggestions), but does anyone know of a decent open source lat/lon-to-timezone package that runs _standalone_ (as opposed to querying a server somewhere)? I am aware of a few networked solutions (e.g. earthtools) and at least one commercial package (askgeo). The former won't work standalone, while the site license for the latter is too steep for my noncommercial, one-off project. Thanks very much in advance, HJ
Time Zone Master, from relativedata.com, is a windows program that does this type of calculation internally. Of course there are limitations, since (especially in north america) very small areas can have differing zones than those around it. It uses a proprietary algorithm and open source databases to make a best-bet estimate of lat-lng to tz, and is quite good at it. The programme is free from our site, and is packaged as a desktop clock application, but if you are looking for a more specific product for your needs, the internal latlong->tz engine could be rebuilt into something more suitable. Let me know what you are looking for. On 2012-03-01 20:46, H J wrote:

Hi, I have written a C# application that uses data from the tzmap database some time ago. You give it your lat/lng coordinates and it gives you the local timezone name from there. I was planning to publish my tz-related tools sometime in the future, but I could send you a copy of it now if you wish. -- Yves Goergen "LonelyPixel" <nospam.list@unclassified.de> Visit my web laboratory at http://beta.unclassified.de

Hi I would be interested in such a copy as well. I had to reply to the list, because your email address does not look like a usable one.

You have mail.

Hm, I was hoping that spam bots would think that my address is wrong, not humans. But it's plain simple, the address is correct. :) -- Yves Goergen "LonelyPixel" <nospam.list@unclassified.de> Visit my web laboratory at http://beta.unclassified.de
Bill Seymour, your e-mail address was unusable. My e-mail to you was not delivered. Just fyi. -- Yves Goergen "LonelyPixel" <nospam.list@unclassified.de> Visit my web laboratory at http://beta.unclassified.de

Hi Yves, That sounds very much along the lines of what I was looking for. I would very much appreciate a copy of your application if you are willing to send it. I should point out that my little project is going to take me some time to build (I want to do the HW first), so although I'm not much of a C# hacker, I can provide detailed feedback as and when I am able to do so. Thanks in advance, --HJ
