I'm looking for an API providing accurate timezone data.

Thus far managed to find earthtools api but daylight saving time info isn't very accurate.

I need to lookup by latitude/longitude or as an alternative (either one or the other is fine) based on <city,country>

Any ideas?

  • I think this is a question more suited to researching/asking at the Open Data Stack Exchange.

Check out The Google Time Zone API. It provides timezone info based on lat/lon.
