Question

Is there a good way to get Timezone information with DST information from a lat/long coordinate or a physical address?

I’ve found some web services that seem to offer this service, but I can’t tell how reliable they might be, or if they might disappear at some point. I need something for my application that will be around long term.

• http://www.earthtools.org/webservices.htm#timezone
• http://www.geonames.org/export/web-services.html#timezone

Are these services reliable and long-term? Are there other, better options?

Answer 1

The answer in this other question is a great solution to this question – Determine timezone from latitude/longitude without using web services like Geonames.org
