问题
From what I have researched it is not possible to change the Timezone of a thread. So my question is why can't you?
I would have thought switching your application's culture to a specific country would also switch this, seems like expected behaviour IMO.
Edit
After revising I can see the reason why it probably shouldn't be mapped 1:1 by default. However, I still feel it would be a nice feature to be able to change the Timezone per thread.
回答1:
They aren't a 1:1 so they're not really connected. If you set the current culture to en-US, which timezone is that? :)
Several countries have more than 1 timezone, so setting the culture (which is not country specific either for that matter), doesn't really have much to do with the timzone.
回答2:
Culture is one thing, time zone is another. Suppose you're a South African citizen working in New York, USA. Obviously you want your time zone to be EST (GMT -5), since that's where you are; from what you're suggesting, however, then if you also set your culture to "af-ZA," as you might want to, doing so would automatically change your time zone to GMT +2.
