title: HttpCookie.Expire timezone implications?
body: <p>I'm trying to write cookies from my website and I'm trying to figure out what implications timezones has over the HttpCookie.Expire property. Should I be passing <code>DateTime.Now.AddDays(1)</code> or <code>DateTime.UtcNow.AddDays(1)</code> or the users's timezone plus a day?</p>
