You cannot retrieve the timezone without something running on the client (i.e. JavaScript) as ASP.NET is server-side.

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.

The basic approach is to use a date and read the TZ info from it.

Since there's no standard (cross-browser time zone naming functions - you have to resort to something like (yikes!):

<pre><code>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();
