Date formatting (BST and GMT)

[dj4uk]

I'm using the RFC1123 date format on my website so a date formats in the following format: Tue, 10 Dec 2002 22:11:29 GMT
using the following code:

String.Format("{0:r}", DateTime.Now);

The question I have is does this string take into account if the server is running on British Summer Time and therefore append BST instead of GMT. If not does anyone know of a way of doing it?
