映射位置的时区 [英] mapping location to a time zone

问题描述

我需要的时区，一个给定的地址/位置。假设地址/位置可以反向地理codeD（使用谷歌）纬度/经度如果必要的。

I need to get the time zone for a given address/location. Assume that the address/location can be reverse geocoded (using google) to a lat/lng if necessary.

这意味着我可能不会有一个zip code。

This means that I may not have a zip code.

我真的很希望，谷歌为此提供了某种形式的API，但似乎他们不这样做。至少你可以谷歌搜索华盛顿时间，并获得时间/ TZ - 但后来我不得不屏幕刮那不是好玩：（

I was really hoping that google provided some kind of API for this, but it seems that they don't. At a minimum you can google search for "time in washington, dc" and get the time/TZ -- but then I'd have to screen scrape that which is not fun :(

我知道有可用的地图位置来时区数据库，但不得不进行维护。有没有人想出了一个棘手的解决这个问题？

I know there are databases available that map locations to time zones, but that'd have to be maintained. Has anyone come up with a tricky solution to this problem?

谢谢！
