问题描述
能否在 ASP.NET 中获取浏览器时区,还是必须依靠 JS 操作来检索信息
Can I get the browser time zone in ASP.NET or do I have to rely on JS operations to retrieve the information
推荐答案
没有Accept-Timezone"标头(或类似的) - HTTP 标准不包含任何工具来允许浏览器自动告诉服务器什么用户关心的时区.
There is no "Accept-Timezone" header (or the like) - the HTTP standard does not contain any facility to allow the browser to automatically tell the server what time zone the user cares about.
基本方法是使用日期并从中读取 TZ 信息.
The basic approach is to use a date and read the TZ info from it.
由于没有标准(跨浏览器时区命名功能 - 您必须求助于(哎呀!):
Since there's no standard (cross-browser time zone naming functions - you have to resort to something like (yikes!):
function getTimezoneName() {
tmSummer = new Date(Date.UTC(2005, 6, 30, 0, 0, 0, 0));
so = -1 * tmSummer.getTimezoneOffset();
tmWinter = new Date(Date.UTC(2005, 12, 30, 0, 0, 0, 0));
wo = -1 * tmWinter.getTimezoneOffset();
