DateTimeOffset和时区更改 [英] DateTimeOffset and time zone change

问题描述

考虑一个简单的代码：

Consider a simplee code:

static void Main(string[] args)
{
    while (true)
    {
        Console.ReadKey();
        Console.WriteLine(DateTimeOffset.Now.ToString());
    }
}

每次按任意键，我都会获得当前时区。

现在当我更改时区，并再次询问日期时 - 我得到相同的时间，即没有应用任何更改。再次运行应用程序后，更改发生了，我终于看到了时区的时间，我设置了。



有人能解释我，如何获得实际没有重新加载应用程序的时间+时区？



谢谢

Each time I press any key, I get the current time with timezone.
Now when I change the timezone, and again "ask the date" - I get the same time, i.e. no changes are applied. After running the application again, the changes take place and I see at last the time from the timezone, I set.

Could somebody explain me, how to get the actual time+timezone without reloading the application?

Thanks

推荐答案

检查 TimeZone.CurrentTimeZone [ ^ ]查看进程是否收到有关更改的通知。时区是线程上下文，它不会遵循系统时区的变化。你必须抓住这样的事件。据我所知，没有具体事件，但附近：请参阅此主题： http://stackoverflow.com/questions/9725180/c-sharp-event-to-detect-daylight-saving-or-even-manual-time-change [<一个href =http://stackoverflow.com/questions/9725180/c-sharp-event-to-detect-daylight-saving-or-even-manual-time-changetarget =_ blanktitle =New Window > ^ ]

Check with TimeZone.CurrentTimeZone[^] to see if the process got notified about the change. Timezone is thread context, it will not follow the system timezone changes. You have to catch such events. As I know there is no specific event, but near: see this topic: http://stackoverflow.com/questions/9725180/c-sharp-event-to-detect-daylight-saving-or-even-manual-time-change[^]

DateTimeOffset.Now 使用 TimeZoneInfo 并在启动时缓存时区。



清除缓存通话：

DateTimeOffset.Now uses TimeZoneInfo and it caches timezone on startup.

To clear the cache call:

TimeZoneInfo.ClearCachedData();

这可以解决你的问题： - ）

This should solve your problem :-)
