您仍然可以解决您的问题，可能准确性有限，但这将是一项不切实际的艰巨任务.首先，您将需要一个巨大的数据库.如果我认为这样的任务是现实的，我会想到这样一个数据库的结构.我不这么认为.我不知道互联网上是否存在这样的服务；在这种情况下，您可以使用它.

In principle a surjective function exists which maps each geographical location to a zip code, but there is not a simple formula which could be used to find this mapping.

This is because the boundaries between time zones are not just defined by physical location; they are defined taking into account subdivision of the land into administrative units such as regions, counties, states, etc, historical tradition, "convenience" (in many cases very much of inconvenience if fact) and many similar cultural factors.

You still can solve your problem, probably with limited accuracy, but this would be an unrealistically huge task. First of all, you will need a huge database. I would think of a structure of such database if I thought such task is realistic. I don''t think so. I don''t know if such service exists in Internet; in that case you could use it.
