问题描述
在Windows上的C ++中，给定城市，可以说伦敦，纽约，悉尼或新加坡等.如何找到每个城市的UTC偏移量，即函数应该能够接受城市名称并返回城市名称当前情况下的UTC偏移量，即考虑到夏令时.关于如何使用Win32 API做到这一点的任何想法
In C++ on Windows, given a city, lets say london or newyork or sydney or singapore etc.. how do I find the UTC offset for each of them, ie the function should be able to accept a city name and return the UTC offset in the current scenario ie taking into account daylight savings. Any ideas how this can be done using win32 APIs
推荐答案
听起来像您想要的API，用于搜索 zoneinfo/tz 数据库..?
Sounds like you want an API for searching the zoneinfo / tz database..?
不知道是否存在一个具有所需接口的库.但是自己阅读和搜索并不困难.它只是一个平面文件数据库，每行只有一条记录.
Don't know if there is a library with precisely the interface you want. But reading it and searching it yourself would not be difficult. It's just a flat file database, text with one record per line.
